Understanding the keyway dimension that is often overlooked When discussing a keyway, most machinists immediately focus on two dimensions: width and length. However, there is a third dimension that plays a major role in tooling selection and broaching feasibility. CNC Broach Tools refers to this radial depth as the Height

Cutting Keyways in Heat-Treated and Defense-Grade Alloys
What changes when material hardness increases Cutting a keyway in mild steel is one thing. Cutting the same feature in heat-treated alloy or a defense-grade material is another. As hardness increases, so do cutting forces, tool wear, and the risk of poor surface finish. Shops working in aerospace, maritime, and
