Speeds and Feeds Calculator

FeedMAXSpeeds & feeds calculator for NEXGEN solid carbide end mills

These are starting parameters for solid carbide end mills in a rigid setup with good tool holding and coolant or air blast. Adjust for your machine, workholding, tool stick-out and tool path. For application help, contact NEXGEN Tooling at (855) 263-2328.

Slotting: Full-width cut (100% of diameter). Chip load in inches per tooth (IPT).
