The M18 FUEL STRIKER (3771-20) is a cordless hammer chisel going directly after the air hammer market. It uses a proprietary linear impact mechanism to deliver 7 joules of impact energy at up to 3,000 beats per minute, roughly equivalent to a 145 PSI air hammer at the upper end of its range. A .401 round shank mount means it takes the same bits as a standard air hammer. Launch date is September 2026, price is $599 tool only.

What the STRIKER Is and What It Replaces
Air hammers are standard in automotive shops for removing frozen exhaust bolts, breaking loose seized brake hardware, driving chisels for body work, and cutting through rusted fasteners. They need a compressor, an air hose, and a shop with compressed air infrastructure. That’s fine in a fixed shop. It’s a problem on mobile service trucks, in a parking lot, or anywhere you’re working away from stationary air.
The STRIKER runs on any M18 FUEL battery and delivers a ramp-adjustable 0-3,000 BPM. The .401 round shank is the industry standard, so existing air hammer bits (chisels, punches, pickle fork attachments) drop right in without adapters. Automotive technicians already running the M18 FUEL platform are the primary target.
This makes the STRIKER an interesting tool for our auto and garage tools section, since it bridges the power tool and automotive service worlds in a way most cordless tools don’t.

Who Should Care
At $599, the STRIKER is priced at the professional end of the market. At that price point, it makes sense if you’re a mobile mechanic or shop tech who already runs M18 FUEL and wants to eliminate one more compressed-air dependency. It’s probably not the right call for the occasional home mechanic who rarely touches an air hammer, where a corded electric hammer or a cheap 3/8-in. impact wrench handles most of the same jobs.
The .401 shank compatibility is the key selling point here. If you have a collection of quality air hammer bits from established use, none of them become obsolete. The tool adds cordless freedom to an existing tooling investment.
A tech who owns the full M18 FUEL set will find this a logical extension. Home garage mechanics with a working compressor setup will find the $599 price harder to justify unless compressed air is genuinely a limitation in their workflow.
