SK40-ER32-70 CNC milling tool holder for high-precision lathe, industrial supplies

High-quality CNC milling tool holder, model SK40-ER32-70. Manufactured with meticulous craftsmanship, it features a ground internal bore, hardening, and tempering for exceptional strength and durability. Its long service life is ensured by heat treatment in a vacuum quenching furnace, significantly improving the tool holder's hardness.

The tool shank has a protective coating that makes it resistant to corrosion and wear, while also protecting your machine's spindle from wear.

A long-lasting heat treatment effectively eliminates residual internal stresses generated during grinding. Designed specifically for machining operations on CNC machine tools, this tool holder supports spindle speeds of 12,000 rpm or higher, making it ideal for demanding applications. **Product Details:** **Material:** 20CrMnTi **Hardness:** 58±2 HRC **Concentricity Accuracy:** ≤ 0.05 mm **Clamping Range (ER32 Collets):** Approx. 3 ~ 20 mm / 0.1 ~ 0.8 inch **Dimensions:** * Length (L): Approx. 132 mm / 5.2 inches
