For mechanics, service technicians, and transportation maintenance crews, the air hammer has always been one of those shop tools you reach for when the job gets stubborn. Whether you are separating rusted suspension components, pushing out stuck bolts, removing ball joints, or breaking loose parts that do not want to move, a long-barrel air hammer has been a go-to solution for decades.

The problem has always been the hose.

Until now, there has not been a true cordless alternative that could step into the long-barrel pneumatic air hammer category. Milwaukee is changing that with the M18 FUEL STRIKER Hammer Chisel (3771–20), the world’s first cordless hammer chisel built to deliver long-barrel pneumatic striking force without a compressor or air hose in the shop.

Designed as a dedicated cordless solution, the M18 FUEL STRIKER (3771–20) is made to go head-to-head with long-barrel air hammer options commonly used across the industry, including tools from Snap-on, Ingersoll Rand, and Chicago Pneumatic. For technicians who have been asking for a cordless air hammer replacement, this is one of Milwaukee’s most important automotive tool releases yet.

A Cordless Replacement for Long-Barrel Pneumatic Air Hammers

Air hammers typically fall into several categories, including compact, medium barrel, long barrel, and heavy-duty .498 models. For many mechanics, the long-barrel category offers the ideal balance of performance, speed, stroke length, and control for separating parts.

Traditionally, long-barrel pneumatic air hammers are judged by their blows per minute, stroke length, and shop air pressure. This category often runs around 2,300 to 2,700 BPM with a 3-inch to 3.75-inch stroke, giving users the heavy vibration and impact needed to separate stuck parts.

Milwaukee built the M18 FUEL STRIKER Hammer Chisel (3771–20) to target that long-barrel pneumatic space directly. Instead of dragging an air hose across the shop floor or relying on compressor setup, technicians can now get serious striking performance from the M18 cordless platform.

7 Joules of Striking Force Without the Compressor

Powered by Milwaukee’s POWERSTATE Brushless Motor, the M18 FUEL STRIKER (3771–20) delivers 7 joules of striking force. Milwaukee designed this output to match leading long-barrel pneumatic competitors operating at 145 PSI shop pressure.

That means technicians can take on demanding work like suspension teardowns, ball joint removal, tie rods, control arms, and wheel pins with the speed they expect from pneumatic tools, but with the cordless freedom of M18 REDLITHIUM batteries.

This is especially useful in busy shops, fleet maintenance, mobile service work, and transportation repair environments where moving around the vehicle without a hose can make a real difference.

Built for the Maintenance of Things That Move

The Milwaukee M18 FUEL STRIKER (3771–20) is designed for service technicians working on vehicles, fleet equipment, and heavy-use mechanical systems. It is built for the maintenance of things that move, from light-duty automotive work to commercial medium-duty and heavy-duty fleet applications.

Core applications include separating ball joints, suspension parts, tie rods, and rusted components. It can also be used for pushing out rusted bolts, hammering with sockets, ripping vehicle panels, cutting mufflers, cutting bushings, shearing off rivets or bolts, piercing holes for dent removal, weld removal, and exhaust pipe work.

For shops that regularly fight rusted, seized, or stuck components, the STRIKER gives technicians a cordless way to bring impact exactly where it is needed.

Three-Mode Selection for Better Control

One of the biggest advantages of the M18 FUEL STRIKER Hammer Chisel (3771–20) is the amount of control it gives the user. The tool features three mode selections to help technicians match the impact to the job.

Mode 1 delivers 0 to 2,500 BPM. Mode 2 delivers 0 to 3,000 BPM. Mode 3 provides a ramp-up setting from 0 to 3,000 BPM.

That ramp-up mode is especially useful when starting on a sensitive or tight work area. Instead of hitting full power immediately, the tool starts smoother, helping reduce slips and improve accuracy. This can help lower the risk of damaging surrounding parts while still giving the user the power needed to finish the job.

Variable Speed Trigger for Precise Impact

The STRIKER also features a variable speed trigger, allowing users to feather the trigger in all three modes. This gives technicians control from the first contact through the end of the application.

Instead of being locked into one aggressive setting, users can dial in the exact amount of impact needed. This is a major benefit when working around suspension components, exhaust systems, body panels, or other areas where control matters just as much as force.

Universal .401 Round Shank Accessory Compatibility

One of the biggest advantages of the Milwaukee M18 FUEL STRIKER (3771–20) is that it does not lock users into a proprietary bit system.

The tool features a .401-inch round shank twist chuck, making it compatible with standard .401 round shank air hammer accessories. That means many technicians can continue using accessories they already own from brands like Snap-on, MATCO, Cornwell, Mac Tools, and Mayhew.

This opens the tool up to more than 100 different accessory types for targeted applications, including non-rotating chisels, punches, rivet bucking accessories, and tension pin punches.

The twist-style chuck is designed for fast and easy bit removal and insertion, with automatic locking to keep accessories secure during use.

REDLINK PLUS Intelligence for Protection

Milwaukee built the STRIKER with REDLINK PLUS Intelligence, which allows full-circle communication between the tool, battery, and charger. This system helps protect the tool from overload, overheating, and over-discharge during demanding applications.

For technicians using the tool repeatedly throughout the day, that added protection helps support consistent performance and tool durability.

Targeted LED Work Light

The M18 FUEL STRIKER (3771–20) also includes a targeted LED work light that delivers high-definition visibility with minimal shadows. This is helpful when working around suspension components, underbody areas, wheel wells, exhaust systems, and other spaces where lighting can be limited.

Better visibility helps technicians position the chisel more accurately and work with more confidence.

The Milwaukee M18 FUEL STRIKER Hammer Chisel (3771–20) gives mechanics and service technicians a real cordless alternative to the long-barrel pneumatic air hammer. With 7 joules of striking force, up to 3,000 BPM, three-mode selection, a variable speed trigger, .401 round shank compatibility, and the freedom of the M18 REDLITHIUM battery platform, this tool is built to cut the air hose without giving up serious shop performance.

For technicians working on suspension teardowns, rusted components, ball joints, tie rods, exhaust systems, bushings, bolts, and other demanding service applications, the M18 FUEL STRIKER is a major step forward in cordless automotive tools.
