Arccaptain 20V Cordless Brushless Impact Wrench AR-IW100
20V Brushless Cordless
Impact Wrench
1,500 N·m of nut-busting power. Stuck lug nuts, seized axle bolts, rusted trailer hardware — gone in seconds. No air compressor, no cords, no compromise.
Rusted, overtightened, seized — handles what a breaker bar can't touch. The highest nut-busting power in its class.
Brushless motor + 4.0Ah battery. Two packs included — one works while one charges. Never stop mid-job.
Compact enough for wheel wells, engine bays, and tight spaces under any vehicle — light enough to use all day.
3-Mode Torque Control
Full Power When You Need It — Controlled When You Don't
Three selectable forward torque levels plus maximum-power reverse. Match the output to the fastener — never strip a small bolt, never under-power a big one.
Speed & Impact Performance
2,500 RPM — Fast Enough for Any Job
Speed and impact rate work together to drive fasteners efficiently and break seated hardware loose faster. Both numbers are at the top of the 20V cordless class.
Brushless Motor
Built to Last — Runs Cooler, Works Harder
Brushless motors outperform brushed ones in every way that matters for sustained, heavy impact work.
No brush-to-commutator friction. Consistent 1,500 N·m on your 20th lug nut, not just your first.
Brushes degrade and fail. Brushless motors have no consumable contacts — performance stays consistent over years of use.
Less energy wasted as heat, more converted to torque. That is why this tool delivers 60–70 min from a 4.0Ah pack.
Smaller motor, same output. 4 lbs total — fits in engine bays and wheel wells where bulkier tools simply won't reach.
Battery System
4.0Ah Makita-Compatible — Use What You Already Own
Per Charge
Two 4.0Ah packs are included. One runs the tool while the other charges — no downtime, no waiting.
Existing Makita Batteries
Any Makita 18V / 20V battery slides right in. No adapter, no proprietary lock-in. The widest battery platform in the trades.
20V vs 18V: Same cells, different label. 20V is peak voltage off the charger; 18V is operating voltage under load. Fully cross-compatible with all Makita-platform batteries.
Built For
Every Job — Road, Shop, or Field
Four wheels done in under 5 minutes. Overtightened lug nuts on trucks and SUVs come off without a second thought.
Axle nuts and strut bolts come off clean at 1,500 N·m. No breaker bar assist, no penetrating oil wait.
Hardware left to corrosion for years — full 1,500 N·m reverse breaks it free when nothing else will.
No air compressor, no cord. 60–70 min of runtime covers most field service calls on a single charge.
Mode 1 (500 N·m) keeps you from stripping oil drain plugs, valve covers, and intake manifold bolts.
Fast forward torque for frame bolting and fixture work. Reverse for teardown and adjustments.
What's In the Box
Complete Kit — Ready to Work Immediately
20V brushless, 1/2 in drive, 4 lbs — with built-in LED work light.
Makita-compatible 20V — 60–70 min each. One works while one charges.
Works with your full Makita-platform battery range.
Impact-rated 1/2 in drive. Covers the most common automotive fastener sizes.
Illuminates the fastener automatically — under vehicles, inside engine bays, wherever light doesn't reach.
Mode guide, torque reference, battery care, and safety information.
Included Sockets — 1/2 in Drive
Safety: Always use impact-rated sockets. Standard chrome sockets can shatter under high torque. All 6 included sockets are impact-rated.
