It carries a 7\/64 inch (0.1094 inch) cutting diameter with a 3\/8 inch length of cut, a 1\/8 inch shank diameter, and a 1-1\/2 inch overall length. The three-flute, spiral configuration runs a 40-degree helix angle with a right-hand cut and right-hand flute direction. An AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life in demanding cutting conditions. The micrograin carbide substrate supports fine edge retention at higher surface speeds. This tool is installed and operated by machinists and CNC tooling technicians in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill fits regular-length milling applications where a small-diameter, three-flute geometry is needed for slotting, profiling, and peripheral cuts. The centercutting design allows plunge entry directly into the workpiece. The 40-degree helix promotes efficient chip evacuation and reduces cutting forces on thin walls or small features. Extended reach is not available on this configuration, so it is suited to shallow-to-moderate depth cuts within its 3\/8 inch length of cut. It is appropriate for use in CNC machining centers and manual knee mills where 1\/8 inch collet or end mill holders are available.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate for fine edge retention and dimensional stability\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral design with 40-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of plus 0.000 \/ minus 0.002 inches for consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a regular-length square end mill for use with 1\/8 inch end mill holders or collet chucks in CNC machining centers and manual milling machines requiring a 7\/64 inch cutting diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is 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 holder. Seat the shank fully to the recommended gauge line in the collet or holder and torque the retention hardware according to the holder manufacturer specifications. Verify runout with a dial test indicator before commencing cuts to protect both the tool and the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/64 inch (0.1094 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.000 \/ minus 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 \/ minus 0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 12181937\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737519063346,"sku":"12181937","price":28.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/599e9b0ab91ca97f4a455b2e05b0f2d6.jpg?v=1788789662","url":"https:\/\/voomisupply.com\/products\/accupro-12181937-square-end-mill-7-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
