Milwaukee 5-Piece Hammer Chisel Bit Set, Model 49-16-3776, is a five-piece accessory kit built for .401 in round shank hammer chisels. This is a hammer chisel bit set designed for metal removal, panel separation, fastener work, and spot weld breaking. It is a strong fit for body shops, fabrication work, fleet maintenance, and anyone using a pneumatic or cordless hammer chisel who wants the common working ends in one box.

The big selling point here is coverage. Instead of buying one bit at a time, Milwaukee puts together the profiles that actually get used: a flat chisel for removing fasteners, separating parts, and controlled shearing; a round hammer for hammering fasteners and breaking rust; a tapered punch with a 5/16 in taper for driving axles; a slotted sheet metal ripper for ripping sheet metal; and a spot weld breaker for breaking spot welds. If your work bounces between teardown, panel work, and stubborn hardware, this set makes more sense than piecing it together later.

Fit matters on air hammer accessories, and Milwaukee keeps this simple with a universal .401 in round shank. That means the set is compatible with all .401 round shank pneumatic and cordless hammer chisels, and Milwaukee specifically recommends it for the M18 FUEL STRIKER Hammer Chisel. For a shop already running that platform, this gives you a ready-to-go set of attachments without guessing on interface.

Material and finish are just as important as shape on accessories like this. Milwaukee builds these bits from durable steel and adds a black oxide coating to help resist rust and corrosion in harsh job conditions. That is useful in real work, because these bits spend their time around bare metal, road grime, seized hardware, and moisture. A coated steel bit is less likely to turn into a rusted mess after a few rough jobs.

At 6.5 in bit length, these chisels give you enough reach for common automotive and sheet metal tasks without getting awkward in hand. The length works well when you need control around suspension parts, body panels, brackets, and weld points. On hammer chisel accessories, too much length can feel sloppy, and too little can make access a problem. This set lands in a practical middle ground for general shop use.

Who should buy it? If you already own a compatible .401 round shank air hammer or cordless hammer chisel and regularly deal with rusted parts, body panel separation, axle work, or sheet metal cutting, this set earns its keep fast. If you only need one profile for one job, buying a single bit may be enough. But if you want a smart starter set for a hammer chisel system, the Milwaukee 5-Piece Hammer Chisel Bit Set covers the jobs most users run into first.
