Built from micrograin carbide and finished with an AlTiN coating, this tool handles elevated cutting temperatures while maintaining edge integrity. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. With a 1\/16-inch cutting diameter and 3\/16-inch length of cut, it is sized for fine detail work, slotting, and profiling in small or precision-machined features. It is installed and operated by machinists and CNC programmers in job shop, tool room, and production machining environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits applications requiring a small-diameter, high-rigidity cutting tool. The 1\/8-inch shank diameter accommodates standard collet chucks and end mill holders. The centercutting geometry allows plunge entry as well as conventional peripheral milling. Right-hand cut and right-hand flute orientation follow the most common spindle configuration. The AlTiN finish makes it well suited for dry or semi-dry cutting of hardened steels, stainless alloys, titanium, and heat-resistant superalloys where coolant may be limited or undesirable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides thermal protection and extended tool life in hard or abrasive materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute for standard CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eTight mill diameter tolerance of plus 0.0005 \/ minus 0.0000 inches supports precision part features\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank square end mill with a 1\/8-inch shank diameter, compatible with ER collet chucks, end mill holders, and precision chucks configured for 1\/8-inch tooling in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or changing tooling. Seat the shank to the full recommended gauge-line depth in the holder and verify runout with a dial indicator before beginning a cut. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\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\/Finish\u003c\/strong\u003e: AlTiN\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\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0005 \/ minus 0.0000 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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12177067\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741879140658,"sku":"12177067","price":39.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bb11d4e39198b714f3b8a11b83e8512.jpg?v=1788834002","url":"https:\/\/voomisupply.com\/products\/accupro-12177067-square-end-mill-1-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
