Broaches | McMaster-Carr

Use individual keyway broaches in a variety of arbor hole sizes. Bushings rest inside the arbor hole of your workpiece and act as guides to ensure rigid and accurate keyway cutting.

Keyway Broach Sets

Sets contain combinations of broaches and bushings and include the necessary shims.

Shims for Keyway Broaches

When broaching in multiple passes, shims are necessary to ensure full keyway depth.

Single-Pass Keyway Broaches

Save time by cutting keyways in one pass. These broaches are longer and have thicker teeth than standard broaches, so you won’t need multiple passes or shims.

Square Broaches

Transform round holes into finely finished square holes.

Rotary Hex Broaches

Used in CNC and milling machines, these broaches turn round holes into hexagonal ones with more accuracy than traditional push broaches.

Rotary Square Broaches

Changing round holes into a square shape more accurately than traditional push broaches, these broaches go in CNC and milling machines.

Holders for Rotary Broaches

Use these holders to secure your rotary broach in a lathe, milling machine, or CNC machine.

Hex Broaches
