Built from solid carbide and coated with AlTiCrN, this tool offers strong heat and wear resistance in demanding cutting applications. It runs a 5\/32 inch (0.1562 inch decimal) cutting diameter with a 0.1450 inch length of cut and a 3\/16 inch shank diameter. The four-flute geometry with variable index provides improved surface finish and reduced chatter compared to evenly spaced flute layouts. Machinists and tool-and-die professionals reach for this size in close-tolerance finishing work.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on hardened steels, stainless steels, and high-temp alloys where AlTiCrN coating performance is an advantage. The compact 0.1450 inch length of cut and 0.2500 inch neck length make it appropriate for controlled-depth profiling and semi-finish passes in CNC machining centers. The 2 inch overall length fits standard ER and collet-style toolholders commonly used in vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard-material applications\u003c\/li\u003e\n\u003cli\u003eAlTiCrN coating provides excellent oxidation resistance and thermal stability at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and improves surface finish\u003c\/li\u003e\n\u003cli\u003eFour-flute design increases material removal rate relative to two- or three-flute alternatives\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 3\/16 inch shank for use in standard collet toolholders\u003c\/li\u003e\n\u003cli\u003e0.2500 inch neck length supports reach into shallow pockets without excessive overhang\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard cutting tool for CNC machining centers accepting a 3\/16 inch shank diameter in ER, collet chuck, or equivalent toolholding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed by a qualified machinist with the spindle fully stopped and locked out per shop lockout\/tagout procedures. Seat the shank fully into the toolholder and torque the collet nut to the toolholder manufacturer's specification using the appropriate spanner wrenches. Inspect the cutting edges and coating for chips or damage before mounting. Verify runout with a dial indicator before initiating a cutting pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 5\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.1562 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1450 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.034 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 32497851\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748828184882,"sku":"32497851","price":82.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/987cec9338efc7b3264e819bbdc9642c.jpg?v=1788899141","url":"https:\/\/voomisupply.com\/products\/accupro-32497851-ball-end-mill-5-32-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
