18-Piece HSS Keyway Broach Set Cut clean, accurate keyways with the Busy Bee Tools 18-Piece HSS Keyway Broach Set. Designed for precision machining and metalworking applications, this set includes four broaches, nine guide bushings, and five shims for creating keyways in a range of bore sizes. Each broach features graduated taper teeth that remove material progressively for smooth, controlled cutting. For keyways requiring additional depth, the included shims allow the broach to be passed through the workpiece multiple times until the required depth is achieved. The broaches are made from high-speed steel for hardness, wear resistance, and lasting cutting performance. Using an appropriate cutting fluid is recommended to help improve cutting action and extend tool life. All components are organized in a fitted wooden case for convenient storage and protection.

A keyway broach set is used to cut internal keyways in compatible gears, pulleys, shafts, and other bored components. How many pieces are included in the set? The set includes 18 tooling components: four broaches, nine bushings, and five shims. A fitted wooden storage case is also included. Why are bushings required? The bushings guide and support the broach through a compatible bore, helping keep the keyway properly positioned during cutting. What are the shims used for? The shims are placed behind the broach during additional passes to progressively increase the depth of the keyway. What material are the broaches made from? The broaches are made from high-speed steel for hardness, wear resistance, and lasting cutting performance. Should cutting fluid be used? Yes. Using an appropriate cutting fluid is recommended to support smoother cutting and help extend broach life. Does the set include both B- and C-style tooling? Yes. The set includes B- and C-style broaches with matching B- and C-style bushings.
