Carbide end mills for stainless steel
The solid carbide end mill series in our catalogue recommended for stainless steel (ISO M) – diameter, flutes, coating, hardness limit and 2026 catalogue cutting data in one table.
The right end mill for stainless steel depends on the operation (slotting, side milling, roughing), the reach required and the hardness of the part. The series below are the Geppetto end mills whose application range includes stainless steel. Each row links to the product page with full dimension tables and cutting data.
Quick selection guide
- General slotting and side milling: MS series (Z2, Z3, Z4) and the MR corner-radius series.
- High metal removal: MC, MC (Z4) and serrated MRS roughing end mills.
- Deep pockets and tall walls: MLR, MSXM, MCL, MCX and MRC long-neck series.
- Polished version: MPR series.
