3-Flute Aluminum End Mill D8 – High Polished, Uncoated 4-Flute Square End Mill D10 – TiCN Coated, HRC60, for Hardened Steel

Product Details

This 4-flute solid carbide square end mill is designed for precision micro machining of hardened steels up to HRC 55. The TiN (titanium nitride) coating provides low friction and increased wear resistance, enabling clean cuts in mold details, electrode machining, and small precision components. The 1.3mm cutting diameter allows intricate contouring and slotting in tight spaces.

The straight shank (1.3mm) ensures accurate clamping in collet chucks. With an ultra‑short flute length (approx. 3mm) and overall length adequate for micro applications, this end mill minimizes deflection while maintaining accessibility. The 4‑flute geometry delivers good surface finish in finishing passes, while the TiN coating extends tool life in abrasive materials.

Typical applications include micro mold cavities, engraving, medical device components, and watchmaking parts. Custom diameters (0.5‑3mm), lengths, and alternative coatings (AlTiN, DLC) are available for OEM orders. For demanding micro milling in HRC55 materials, this TiN‑coated end mill offers reliable performance.
