Built from M42 cobalt high-speed steel, this single-end tool features a 0.5 inch cutting diameter, a 1 inch length of cut, and a 3\/8 inch shank diameter with an overall length of 2-11\/16 inches. The three-flute geometry and 30-degree right-hand spiral helix provide a balance of chip evacuation and cutting stability. The centercutting design allows plunge entry directly into the workpiece. Machinists and tool-and-die professionals install this end mill on manual and CNC milling machines for slotting, profiling, and pocket operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general-purpose milling in job shop, production, and maintenance environments. The M42 cobalt grade handles elevated cutting temperatures better than standard M2 HSS, making it appropriate for stainless steels, alloy steels, and other harder ferrous workpiece materials. The Series 531 regular-length configuration fits standard tool holders and collet chucks used in knee mills and vertical machining centers. It runs uncoated, which simplifies resharpening when needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eThree-flute design balances chip clearance and tool rigidity for ferrous materials\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand helix with right-hand cut for smooth, efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eUncoated finish simplifies resharpening on standard tool grinders\u003c\/li\u003e\n  \u003cli\u003eSeries 531 regular length fits standard collet chucks and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for use in milling machines accepting a 3\/8 inch shank diameter end mill holder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or CNC operators. Power down and lock out the machine spindle before seating or removing the tool from the holder. Ensure the shank is fully seated and the set screw or collet nut is properly secured before operation.
