Built from micrograin carbide stock and finished with an AlTiN (aluminum titanium nitride) coating, this tool handles hardened materials, stainless steels, and high-temp alloys where HSS tooling falls short. The cutting diameter is 0.0469 inches (3\/64 inch) with a 9\/64-inch length of cut and a 1\/8-inch shank diameter. Overall length is 1.5 inches. The 40-degree helix angle promotes efficient chip evacuation at high spindle speeds while reducing chatter on fine-feature cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills running small-feature work in die and mold, medical device, electronics, and aerospace component production. The centercutting geometry allows plunge entry without a pre-drilled hole. Right-hand cut and right-hand spiral flute configuration are standard for conventional and climb milling operations. The 1\/8-inch shank fits standard collet chucks and ER-style toolholders commonly found in production shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends tool life in dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a starter hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle direction compatibility\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker and no variable helix  -  consistent geometry suited to fine-feature finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 1\/8-inch round shank with ER collet, straight-bore, or set-screw toolholders.

Ensure the spindle is fully stopped and the machine is in an energy-isolated state before loading or removing tooling. Seat the shank to the full recommended collet depth to minimize runout and prevent pullout under cutting loads. Confirm shank diameter tolerance compatibility with the toolholder before clamping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/64 inch (0.0469 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0005 \/ -0.0000 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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/64 inch (0.1406 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\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\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: 12177065\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741218636082,"sku":"12177065","price":39.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f901697e5231a98b24076d05cabb56f5.jpg?v=1788830116","url":"https:\/\/voomisupply.com\/products\/accupro-12177065-square-end-mill-3-64-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
