It features a 0.125 inch mill diameter, a 1 inch length of cut, and a 3 inch overall length, mounted on a 0.5 inch straight cylindrical shank. The 0.030 inch corner radius reduces stress concentration at the cutting edge, extending tool life in high-load applications. A variable helix and variable index geometry break up harmonic vibration, minimizing chatter during aggressive cuts. The proprietary PROMAX PowerLayer coating provides thermal and abrasion resistance across a wide range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for use in CNC machining centers and toolholder setups where consistent performance across ferrous and non-ferrous materials is required. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and non-ferrous metals. The coarse pitch, right-hand flute spiral, and centercutting capability make it suitable for slotting, profiling, and plunge operations in production and job-shop environments. It is a single-end, extra-long series tool from the PROMAX US007 family.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.030 inch corner radius reduces edge chipping and extends tool life in interrupted cuts\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index design suppresses chatter for improved surface finish\u003c\/li\u003e\n\u003cli\u003eSolid carbide micrograin substrate provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003ePROMAX PowerLayer coating improves heat resistance and lubricity for dry or minimal-coolant cutting\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral, 4-flute configuration balances chip evacuation with cutting efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting a 0.5 inch cylindrical shank.
