It features a 1\/16 inch cutting diameter, a 0.01 inch corner radius, and four flutes arranged in a right-hand spiral configuration. The AlTiN (Aluminum Titanium Nitride) coating provides high-temperature hardness and oxidation resistance, making this tool suitable for dry or semi-dry cutting at elevated speeds. The micrograin carbide substrate supports sharp edge retention and extended tool life in demanding cutting conditions. A licensed machinist or tooling technician installs and operates this end mill in a CNC machining center or manual milling machine.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish and semi-finish milling passes where a controlled corner radius is required to reduce stress concentrations in machined profiles. The centercutting design allows plunge entry, enabling slotting, profiling, and pocketing operations. The 3\/16 inch length of cut and 1-1\/2 inch overall length make it appropriate for shallow-depth work in tight cavities or on small workpiece features requiring tight dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating for high-heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and sharp edge retention\u003c\/li\u003e\n\u003cli\u003e0.01 inch corner radius reduces stress risers and improves surface finish at part corners\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports plunge entry for slotting and pocketing\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eSingle-end design with a 1\/8 inch shank for use in standard collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual milling machines equipped with collet toolholders accepting a 1\/8 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet holder. Verify collet size matches the 1\/8 inch shank before tightening to avoid runout. Do not exceed the recommended depth of cut for the 3\/16 inch length of cut to prevent tool deflection or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/16 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002 \/ -0.0008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +\/- 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.13 x 0.25 x 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 12176899\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750455181618,"sku":"12176899","price":31.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4abdf9b02c2332d72522b071a35665fe.jpg?v=1788915591","url":"https:\/\/voomisupply.com\/products\/accupro-12176899-corner-radius-end-mill-1-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
