Workpiece Hardness and Cutting Speed
Getting the best results from a broach requires matching process parameters to the workpiece material.
The ideal workpiece hardness range for broaching is generally HB 200 to 230 (approximately HRC 14 to 21), though materials up to about HB 300 (HRC 32) are commonly broached without issue. Material that is too soft can cause adhesion on the tooth flanks and lands, resulting in poor surface finish with tearing or flaking. Material that is too hard will accelerate broach wear and shorten tool life.
Cutting speed is another critical variable, influencing both dimensional accuracy and tool longevity. Recommended speeds vary by workpiece material—ferrous alloys, cast irons, and non-ferrous metals each have their own optimal ranges. Staying within the recommended speed window for a given material is one of the simplest ways to maximize broach life and part quality.
