Broaches

0 products

Broaches are precision tools designed for creating keyways, splines, and various shapes within holes during metalworking processes. They efficiently transform round holes into square, rectangular, or polygonal configurations. Keyway broaches, featuring cutting teeth along their bar-shaped body, are essential for crafting exact keyways in components like pulleys, gears, and washers, ensuring a secure fit with keyed shafts. Rotary broaches offer a solution for producing precise polygonal holes in a single operation, ideal for fastener sockets and similar applications. The process is supported by bushings for guidance and shims for depth control, enhancing accuracy and efficiency.
