Built from high speed steel (HSS), this single-end tool features a 0.1719-inch (11\/64 inch) cutting diameter and a 7\/16-inch length of cut. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces during operation. With a right-hand cutting and right-hand flute direction, it is compatible with standard CNC machining centers and manual milling machines. The bright, uncoated finish makes it well suited for use in softer metals and general shop materials where coating is not required.\u003c\/p\u003e\u003cp\u003eThis end mill is appropriate for light to medium-duty milling work in job shops, tool rooms, and production environments. It fits standard tool holders with a 3\/8-inch shank and delivers a 2-3\/8-inch overall length that accommodates typical spindle clearances. The centercutting geometry allows plunge cutting as well as peripheral milling, giving machinists flexibility in programming toolpaths. This tool is typically installed and used by machinists and CNC operators working across general metalworking, fabrication, and maintenance machining tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11\/64 inch (0.1719 inch) cutting diameter for small-feature milling\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for general-purpose machining\u003c\/li\u003e\n\u003cli\u003e2-flute design promotes efficient chip clearance in slotting and profiling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for smooth cutting action and reduced vibration\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows both plunge and peripheral milling\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for softer metals and general shop materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard single-end square end mill with a 3\/8-inch shank diameter, compatible with conventional milling machine collets and CNC tool holders sized for 3\/8-inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed by machinists using an appropriate collet or end mill holder matched to the 3\/8-inch shank diameter. Ensure the machine spindle is fully stopped and locked out before securing or removing the tool. Verify runout with a dial indicator after installation to confirm proper seating.
