Broaching Tools: Essential Tooling for Machining Precise Slots, Gears and Complex Shapes
Broaching Tools Broaching is a machining process used to produce linear slots, splines, keyways and general straight features on a workpiece by dragging a toothed cutting tool called a broach through the metal. A broach is a multi-tooth cutting tool with the teeth arranged in a line, much like a hacksaw blade. The teeth successively remove layers of metal as it progresses through the workpiece, producing a smooth accurate surface. This gives broaching the ability to create intricate slots and forms with very high precision and little finishing required. The many teeth also make broaching a fast machining technique. Types of Broaching Tools There are two main categories of broaching tools based on the tool material and construction: solid-tooth broaches and inserts broaches. Within each category there are also sub-types based on the specific application. Solid-tooth Broaching Tools have teeth made from a solid piece of tool steel. They are used for heavier cutting applications and can ...
