About Keyway Broaches

Keyway Broaches

Cut precision keyways. Each tooth’s cutting edge is a few thousandths of an inch larger than the one before. The cutting edges increase until they reach the required size. Broaches are for use in hand and hydraulic arbor presses and are great for maintenance and short-run production operations. They include the required shims to ensure full keyway depth when broaching in multiple passes. A bushing is required (sold separately).
Titanium nitride (TiN) coated broaches offer increased hardness, heat resistance, and lubricity for extended life.
Note: Broaches have a style designation of A, B, B1, C, D, E, or F. For proper fit, broaches, bushings, and shims used together must have the same letter designation.

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. Each tooth’s cutting edge is a few thousandths of an inch larger than the one before. As the broach moves through the material, the increasing size of the teeth gradually shapes the keyway until the final tooth reaches the exact dimensions needed. Since you use these broaches in hand and hydraulic arbor presses, they’re best for maintenance and small-batch manufacturing. A bushing is required (not included).
Note: Broaches have a style designation of A, B, B1, C, or D. For proper fit, broaches and bushings used together must have the same letter designation.
