Milwaukee Electric Tool 49-22-4800 Hole Saw Set, 3 Pieces, 1/4" Hex Shank,

This 3-piece hole saw set provides clean cutting solutions for users working with plastics and thin-gauge metals. Designed specifically for use with impact drivers, it eliminates the need for separate dedicated drill chuck adapters when making quick, precise circular cuts on the job.

The set includes three thin-wall hole saws in essential diameters: 7/8-inch (model 49-56-9810), 1-1/8-inch (model 49-56-9820), and 1-3/8-inch (model 49-56-9830). Each piece is built with a standard 1/4-inch hex shank, allowing quick insertion into standard impact driver chucks. Its durable construction is intended to maintain cutting performance over repeated use.

Material thickness is the primary limitation for this set, as it is engineered specifically for thin-gauge metals and plastics up to 1/8-inch thick. If you need to bore through thicker stock or work with materials outside thin metal and plastic, a different cutting tool will be required.

Verdict: This set is a solid, straightforward choice for anyone who needs to cut 7/8-inch to 1-3/8-inch holes in thin materials using an impact driver. It delivers reliable cutting sizes in a convenient 1/4-inch hex format.
