Master Cutting Speed Chart
The starting point for every job. Recommended Surface Speeds (SFM / Vc) for Milling and Turning across 25+ materials.
Note: These are starting parameters for uncoated carbide tools. Coated carbide (TiAlN, AlTiN) can typically run 20-50% faster. High Speed Steel (HSS) should run at 40-50% of these speeds.
