Product Specifications:
This 3-flute solid carbide end mill is specifically designed for high‑speed, high‑gloss finishing of aluminum and its alloys. The extra‑long overall length (75mm) allows deep cavity milling and extended reach in tall workpieces without sacrificing rigidity. The 3‑flute geometry provides superior chip evacuation, reducing recutting and heat buildup, which is critical for soft, sticky materials like aluminum. The 45° high helix angle further enhances chip flow and minimizes built‑up edge (BUE).
The 4mm cutting diameter features a straight shank of the same size for accurate clamping in collet chucks. Polished flutes offer an ultra‑smooth, low‑friction surface that prevents aluminum adhesion and produces mirror‑like finishes. This end mill excels in slotting, contouring, ramp‑in, and trochoidal toolpaths on CNC machining centers.
Typical applications include aluminum electronic housings, automotive trim, aerospace components, and general high‑quality aluminum fabrication. Custom lengths, corner radii, and optional coatings (DLC, ZrN) are available for OEM orders. For demanding aluminum high‑gloss machining, this extra‑long 3‑flute end mill delivers excellent chip clearance and superior surface quality.
