Built from micrograin solid carbide and coated with AlCrTiN for heat and wear resistance, this single-end, centercutting tool measures 0.1875 inches in diameter with a 4-flute, right-hand spiral configuration and a 38-degree helix angle. The 0.010-inch corner radius reduces stress concentrations at the cutting edge, extending tool life in demanding materials. Overall length is 3 inches with a 7\/32-inch length of cut. Variable index spacing helps suppress chatter during aggressive cuts.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual mills where extended reach into deep pockets, slots, or cavities is required. The reduced neck diameter of 0.178 inches enables clearance in tight geometries. Typical applications include die and mold work, aerospace component finishing, and precision part machining in ferrous and non-ferrous alloys. The AlCrTiN coating makes it especially effective in dry or semi-dry cutting environments at elevated temperatures. A licensed machinist or CNC operator running finish or semi-finish passes will find this tool well suited to high-speed, low-radial-engagement strategies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlCrTiN coating provides oxidation resistance and thermal hardness at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e0.010-inch corner radius reduces edge chipping and stress at the cutting corner\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 3\/4-inch reach length and reduced 0.178-inch neck diameter for deep-cavity access\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/16-inch shank end mill compatible with collet chucks, end mill holders, and shrink-fit toolholders accepting a 3\/16-inch shank diameter.

Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the tool from its holder. Seat the shank to the full recommended grip depth in the toolholder to minimize runout and prevent pullout under cutting loads. Do not exceed the tool manufacturer's recommended cutting parameters for the specific workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 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: 7\/32 inches (0.2188 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.178 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3\/4 inches (0.750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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: AlCrTiN\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\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: 0.01 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: 310745\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730235425074,"sku":"310745","price":62.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e28570f5d3394e58cbc138dbd1e1d3c2.jpg?v=1788713811","url":"https:\/\/voomisupply.com\/products\/accupro-310745-corner-radius-end-mill-3-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
