SpeTool Spiral UpCut CNC Bits 2 Flutes 1/4 inch Shank Extra Long(3 inches) Carbide End Mill TiAlN Coated HRC55

Technical Specifications: HRC55 solid carbide material with TiAlN coating, 1/4 inch shank diameter, 1/4 inch cutting diameter, 1-1/8 inch cutting length, and 3 inch total length. Upcut Spiral Design: The two-flute spiral geometry facilitates upward chip removal during high-speed milling, suitable for deep slotting and preventing heat buildup in stainless steel. Material Hardness Performance: Constructed from HRC55 grade tungsten steel to maintain cutting edge sharpness when processing carbon steel, mould steel, and titanium alloys. Surface Friction Reduction: TiAlN coating provides thermal stability for dry machining and finish processing, extending tool life during side milling on inconel and hardened metals. Machine Tool Compatibility: Engineered for use with CNC engraving machines and automated router tables. Compatible with Makita and Bosch plunge routers with a 1/4 inch collet.
