“What is HiKOKI? Same as the old Hitachi Koki?” “What makes the MultiVolt 36V different?” — This article answers those questions by walking through 10 key HiKOKI power tools from a jobsite perspective.
HiKOKI is the global brand name for the former Hitachi Koki. The company rebranded to “HiKOKI” in 2018 and is now manufactured and sold by Koki Holdings. The technology and reliability built during the Hitachi Koki era continue unchanged, and HiKOKI holds a strong market share across professional construction, M&E, and landscaping jobsites.
メナHiKOKI = former Hitachi Koki. Only the brand name changed — technology, quality, and parts supply continue unbroken from the Hitachi Koki era. Tools released after 2018 carry the “HiKOKI” logo.
The Advantage of HiKOKI’s MultiVolt 36V Technology
What Is MultiVolt (36V/18V Auto-Switching)?
HiKOKI’s greatest strength is the MultiVolt battery (BSL36A18 series). This battery automatically switches between 36V in 36V tools and 18V in 18V tools. In other words, one type of MultiVolt battery covers both 18V and 36V tools.
While Makita’s 40Vmax uses a “40V-dedicated battery,” HiKOKI’s MultiVolt advantage is the ability to share batteries with existing 18V tool investments — making the transition far more cost-effective.
HiKOKI Product Lineup Overview
18V Series (slide-type Li-ion compatible):
Impact driver (WH18DC), vibration driver drill (DV18DD), disc grinder (G18DSL2), driver drill (DS18DBSL), work light (UB18DC), charger (UC18YML2), and more
36V MultiVolt Series:
Circular saw (C3606DA), impact wrench (WR36DC), blower (RB36DA), chainsaw (CS3635DB), and more
→ MultiVolt battery works in both 18V and 36V tools
Makita vs. HiKOKI — Key Spec Comparison
A summary of the differences between the two brands most often compared on professional jobsites:
| Comparison | HiKOKI (MultiVolt) | Makita (40Vmax) |
|---|---|---|
| Battery compatibility | 36V/18V auto-switching (one type for both) | 40V dedicated (not compatible with 18V) |
| Impact driver max tightening torque | 180 N·m (WH18DC) | 220 N·m (TD002GRDX) |
| Main charger | UC18YML2 (DC12V compatible) | DC18RC (AC100V only) |
| Color | Aggressive green | Makita blue |
| Battery management | One MultiVolt type for all tools | 18V and 40V managed separately |
The decision axis is clear: if you already own HiKOKI/Hitachi Koki 18V tools, choose HiKOKI (minimal battery transition cost). If starting fresh and targeting 40V-class output, choose Makita.
Top 10 HiKOKI Recommended Tools
HiKOKI WH18DC Cordless Impact Driver — 18V, MultiVolt Compatible
メナFor impact drivers, HiKOKI is the answer. The triple-hammer strike feel is unlike any other brand. Even driving long screws, the rotation speed never drops — that stability is the difference.
The WH18DC is the flagship impact driver in HiKOKI’s 18V series. The triple-hammer mechanism delivers the fastest fastening speed among domestic 18V cordless impact drivers as of July 2022. Maximum tightening torque of 180 N·m means no speed drop during M16 bolt tightening or driving 150mm+ coarse thread screws — consistent, reliable fastening throughout.
Compact 114mm head length, 1.6kg with battery. Manageable in tight and elevated spaces. Triple LED lighting illuminates a wide area with minimal bit shadow. Install a MultiVolt battery BSL36A18 (18V / 4.0Ah) and it runs as an 18V tool — and when you add 36V MultiVolt tools later, the same battery covers those too.
Compared to the Makita TD002GRDX, the WH18DC’s differentiator is the “balance between strike feel and lightweight design.” While Makita focuses on “precise torque management via custom modes,” HiKOKI’s design philosophy centers on “consistent high-speed striking via triple hammer.” Which is right depends on the task — but on jobsites that prioritize speed (carpentry, structural steel), the WH18DC gets high marks.
HiKOKI DV18DD Cordless Vibration Driver Drill — 18V
メナFor light concrete boring, this is plenty. You get both impact and driver drill functionality in one tool.
The DV18DD is HiKOKI’s 18V cordless vibration driver drill. 3-mode selector — vibration drill / drill / driver — means one tool handles concrete boring at roughly Φ10–13mm, screw driving, and pilot hole drilling. With maximum drill torque exceeding 60 N·m (model dependent), it also handles wood and metal boring.
22-position clutch provides precise torque control, preventing overdriving when setting screws. The compact body is highly maneuverable in tight spaces and overhead positions. Shares HiKOKI’s slide-type 18V batteries (BSL1830, etc.) with WH18DC, G18DSL2, and other 18V tools for unified battery management.
The difference from a hammer drill (DH18DBL, etc.) is “concrete drilling capacity.” A vibration driver drill is limited to light percussion drilling up to roughly Φ13mm — for Φ20mm+ or deep drilling, you need an SDS-equipped hammer drill. As the “first tool” for a jobsite that needs to handle wood, metal, and light concrete in one machine, it’s a practical choice.
HiKOKI G18DSL2 Cordless Disc Grinder — 18V
メナI was impressed at how much power a cordless grinder can put out. Cutting rebar is no problem at all.
The G18DSL2 is a HiKOKI 18V cordless disc grinder with a 100mm (4-inch) wheel. Slide switch design for safe operation. An improved model with enhanced durability, reinforced for sustained use on jobsites. Brushless motor maintains stable output under high load while using battery power efficiently.
The slide switch reduces the risk of accidental activation while still enabling quick switching. Compatible with Φ100mm cut-off and grinding wheels — handles rebar cutting, weld bead grinding, and steel plate deburring across a full range of metal fabrication tasks on site. With an 18V/4.0Ah battery (BSL1840), continuous cutting runtime is approximately 20–30 minutes.
Compared to corded grinders, the biggest difference is “freedom of movement.” For metal cutting in locations where a cord won’t reach, post-weld grinding, and work on scaffolding, the cordless advantage dramatically improves efficiency. The G18DSL2’s limitation is that battery swaps are needed during extended heavy-duty sessions — but a two-battery rotation setup provides practical continuous runtime.
HiKOKI RB36DA Cordless Blower — 36V MultiVolt
メナThe 36V blower is in a different power class. Blows away a pile of wood shavings in an instant. Site cleanup has gotten dramatically easier.
The RB36DA is a HiKOKI 36V MultiVolt-compatible cordless blower. Maximum air volume of 800 m³/h provides powerful airflow for cleanup across construction sites, landscaping, and agriculture. A 5-step airflow switch lets you adjust the volume for the task — from delicate dust removal to clearing large volumes of leaves and wood chips. With a MultiVolt battery (BSL36A18), it runs at full 36V power.
Quieter than a traditional air compressor + air blower setup — usable in residential areas and early morning without disturbing neighbors. Continuous runtime with BSL36A18 (2.5Ah): approximately 10–28 minutes depending on airflow setting. BSL36B18X (4.0Ah) extends this to approximately 20–56 minutes. Lock-off button prevents accidental switch activation.
Compared to the Makita UB002GZ (40Vmax blower), the RB36DA’s key advantage is integration into the HiKOKI MultiVolt ecosystem. It shares batteries with WR36DC, C3606DA, and other 36V MultiVolt tools — one charger and 2–3 batteries manages all 36V tools together. The natural choice for tradespeople already standardized on HiKOKI.
HiKOKI CS3635DB Cordless Chainsaw — 36V, 350mm Bar
メナThe 36V chainsaw’s power is genuine. Cutting through a log around 30cm in diameter is smooth and effortless. An indispensable tool in landscaping and forestry.
The CS3635DB is a HiKOKI 36V MultiVolt-compatible cordless chainsaw with a 350mm (13.8-inch) guide bar. Direct-drive design requires no oil pump warm-up before starting. Going cordless dramatically improves mobility for felling and limbing work in forests and farmland where extension cords can’t reach. Automatic chain oiling reduces maintenance burden.
The 350mm guide bar handles single-pass cuts through logs of approximately 20–30cm in diameter — a practical size for general landscaping, agricultural, and forestry felling work. Weight with battery is approximately 5kg, significantly lighter than an equivalent gas-powered chainsaw, reducing fatigue during extended use. Chain brake (kickback prevention) provides high-safety operation.
Compared to gas-powered chainsaws, cordless wins on “easy starting, zero exhaust, low vibration, and low noise.” It can’t match gas’s “refuel anywhere, anytime” convenience, but for felling work a few times a week year-round, the 36V battery runtime is more than sufficient. For HiKOKI users unifying their tools to battery power, extending MultiVolt to even the chainsaw is a significant benefit.
HiKOKI C3606DA Cordless Circular Saw — 36V MultiVolt, 165mm
メナThe MultiVolt circular saw is the flagship of jobsite cordless conversion. Cutting lumber for timber framing without a cord — that’s revolutionary.
The C3606DA is a HiKOKI 36V MultiVolt-compatible 165mm cordless circular saw. The full 36V power cuts plywood, structural lumber, and 2×4 material at a speed comparable to corded saws. Maximum cutting depth: 57mm at 90°, 40mm at 45° — handling standard lumber dimensions used in conventional and platform frame construction. Comes equipped with a Super Chip Saw “Kurosachi” blade for a high-precision finish.
With a 36V / 2.5Ah battery (BSL36A18), the continuous cut count is approximately 190 sheets of 12mm plywood (manufacturer’s rated figure) — runtime to cover a full day of woodworking. Electronic brake stops the blade within approximately 2 seconds of trigger release, ensuring operational safety. Dust and splash resistance (IP5X equivalent) for stable operation in environments heavy with wood chips and sawdust.
Compared to the Makita HS001GRDX, the C3606DA’s strength is “MultiVolt 36V/18V dual compatibility.” The same BSL36A18 battery is shared with RB36DA, WR36DC, CS3635DB, and other tools — it’s the centerpiece of HiKOKI’s 36V ecosystem. Making the circular saw the first tool to upgrade to 36V lets you experience the battery advantage on your most-used tool.
HiKOKI WR36DC Cordless Impact Wrench — 36V MultiVolt
メナStructural steel tightening has gotten dramatically easier. The 36V torque is completely on par with a corded tool — no compromise.
The WR36DC is a HiKOKI 36V MultiVolt-compatible cordless impact wrench. Maximum tightening torque of 350 N·m and maximum loosening torque exceeding 500 N·m (depending on settings) enables electric bolt tightening for M12–M16 class fasteners. Friction ring socket retention for smooth socket changes, with tightening torque switchable by work mode — wood mode, bolt tightening mode, and more.
1/2-inch (12.7mm) square drive socket compatible — handles tire changes, high-strength bolt tightening in structural steel, and equipment mounting bolt tightening. Going cordless improves safety and efficiency for tightening work on elevated scaffolding, in tight spaces, and outdoors. With a BSL36A18 MultiVolt battery, full 36V power maximizes tightening torque.
As an electric tire changer, the WR36DC has earned a strong reputation among auto mechanics and construction tradespeople as “HiKOKI’s high-torque machine in aggressive green.” High maximum loosening torque means it handles seized wheel nuts too. For HiKOKI 36V series users, extending MultiVolt to the wrench simplifies battery management across all tools.
HiKOKI UB18DC Cordless LED Work Light — 18V, Up to 4,000lm
メナSite lighting shared with battery tools — no generator needed. Setting up for night work has gotten dramatically simpler.
The UB18DC is a HiKOKI 18V cordless LED work light with a maximum brightness of 4,000 lumens. Dial-type stepless dimming adjusts brightness continuously — one light covers everything from fine hand work to full-site illumination. Running 4,000lm from an 18V battery means site lighting can be unified with the power tool battery system.
With an AC adapter (sold separately), it can also draw power from an outlet — no battery level worries for extended lighting use. IP54-rated dust and splash resistance for rain and dusty environments. Carry handle for portability, 360-degree rotating stand for flexible positioning.
Compared to generators and floodlights, the UB18DC’s clear differentiator is “battery lighting shared with HiKOKI 18V tools.” For brief lighting needs in dark spaces or overnight work, existing 18V batteries cover it at no additional cost. On sites where eliminating generator noise and fuel management costs matters, the UB18DC is a practical site lighting option.
HiKOKI UC18YML2 Rapid Charger — 14.4V / 18V
メナUsing this since I went all-in on HiKOKI 18V. Being able to charge from the car’s cigarette lighter socket is genuinely invaluable on a jobsite.
The UC18YML2 is HiKOKI’s rapid charger for slide-type 14.4V/18V batteries. In addition to AC100V (household power), it also charges from DC12V (car cigarette lighter socket) — a dual-input feature that supports charging in forests, farmland, and outdoor sites where power isn’t readily available. With BSL1830 (18V/3.0Ah), it achieves approximately 22-minute rapid charging via AC100V.
Built-in 4-level battery level indicator (LED) — insert the battery to check remaining charge at a glance. Automatically switches to trickle charging when full, preventing over-charge battery degradation. Cooling fan reduces heat buildup during charging, maintaining stable charging speed even in hot summer environments.
The standard charger for HiKOKI 18V tool batteries (BSL1830/1840/1860) compatible with WH18DC, DV18DD, G18DSL2, UB18DC, and more — the ideal first charger when entering the HiKOKI system. The DC12V charging capability means you can charge in your work vehicle while driving between sites — a feature highly valued by tradespeople running multiple HiKOKI tools.
HiKOKI DS18DBSL Cordless Driver Drill — 18V
メナFor driving screws and drilling pilot holes into wood, this is all you need. More precise torque control than an impact driver — plywood splitting has dropped significantly.
The DS18DBSL is HiKOKI’s 18V cordless driver drill. As a clutched driver drill with maximum torque of 70 N·m, it provides the precise torque control needed to prevent overdriving and material splitting. Safely handles precision screw driving and pilot hole drilling where an impact driver (WH18DC) would be “too powerful.” Compatible with HiKOKI 18V/14.4V slide-type batteries — shared with the 18V series.
Drill mode and driver mode for boring in wood, metal, and resin, plus screw driving. Compact and lightweight — excellent maneuverability for extended sessions and tight-space work. LED light ensures clear visibility in dim conditions.
The role division with the WH18DC (impact driver) is clearly defined by “hammering vs. no hammering.” Coarse thread screws and long screws go to the impact driver; precision screw driving, fine woodwork, and clutch-controlled operations go to the driver drill. Having both dramatically expands what you can handle on site. Same HiKOKI 18V batteries — expand your lineup without additional battery cost.
Summary: Strategy for Building Your HiKOKI Tool System
The recommended starting combination for entering the HiKOKI ecosystem: WH18DC (18V impact driver) + UC18YML2 (rapid charger) + BSL1840 (18V/4.0Ah batteries) ×2. This setup establishes operations with your most-used tool — the impact driver — and puts you inside the HiKOKI 18V battery ecosystem.
Recommended HiKOKI System Expansion Sequence
1. 18V Entry: WH18DC + UC18YML2 + BSL1840 ×2
2. 18V Expansion: DV18DD (vibration drill) + DS18DBSL (driver drill) + G18DSL2 (grinder)
3. 36V Transition: BSL36A18 (MultiVolt battery) + C3606DA (circular saw)
*MultiVolt battery also works in existing 18V tools — low transition cost
4. Full 36V: WR36DC + RB36DA + CS3635DB — all heavy tools go cordless
5. Lighting Integration: UB18DC — site lighting unified on 18V battery
メナOnce you start using MultiVolt batteries, the experience of having both 18V and 36V tools run on the same battery is something else. One charger and a handful of batteries to manage your entire tool fleet — that convenience is uniquely HiKOKI.
The final choice between Makita and HiKOKI comes down to how many 18V tools you already own. If you have existing HiKOKI or Hitachi Koki 18V tools, the transition cost to MultiVolt is minimal. For a detailed comparison, see also the Makita 40Vmax Guide.
