Powermatic 1791096 Premium Mortise Chisel & Bits, Set of 4

The Powermatic 1791096 Premium Mortise Chisel & Bits, Set of 4 is a four-piece hollow mortise chisel and bit set built for woodworking joinery on mortising machines. This is a mortise chisel and bit set designed for cutting clean, square mortises in wood. Model Number: 1791096. If you need dependable mortises for doors, frames, furniture, or cabinet work, this set covers the common sizes most shops reach for first.

What matters here is not just that these are replacement accessories, but how they are built. Each chisel and bit is machined from solid bars of carbon steel, then ground and hardened for efficient cutting and long service life. In plain terms, that means the cutting edges are built to stay sharper longer and hold up better when you are making repeated cuts instead of just one or two test joints.

The cutting geometry is set up for real joinery work. Powermatic calls out one cutting edge, one spur, and a brad point on the bits. That combination helps start the cut accurately, pull material out of the center, and leave the walls of the mortise cleaner and more square. For the user, the benefit is simple: less tear-out, smoother side walls, and less time spent cleaning up a mortise before assembly.

Another practical advantage is the extra-long bit design. That added length improves compatibility across different mortisers, which is important if you are outfitting an existing machine or keeping multiple shop machines running. It gives this set more flexibility than short-pattern accessories that only work well in a narrow range of setups.

This set includes four useful sizes: 1/4 inch, 5/16 inch, 3/8 inch, and 1/2 inch. That size spread makes sense for furniture builders, cabinet shops, door work, and general woodworking because it lets you match the mortise to the scale of the stock and the tenon without piecing together a kit from separate purchases. The included case also makes it easier to keep the sizes organized and protected between jobs.

Who should buy it? Woodworkers, cabinetmakers, furniture builders, school shops, and serious DIY users running a mortiser and wanting a ready-to-work set from a known machine brand. If you already own Powermatic equipment, the brand match is a plus. If you are mainly after clean mortising performance and broad size coverage, the Powermatic 1791096 Premium Mortise Chisel & Bits, Set of 4 is a straightforward upgrade over bargain accessories that leave rougher walls and need more tuning.
