Built from micrograin solid carbide and coated with TiCN (titanium carbonitride), this single-end, centercutting tool delivers hard-material performance with extended tool life. It features a 5\/8-inch diameter, a 3-inch length of cut, and a 1\/8-inch (0.1250-inch) corner radius that reduces stress concentration at the cutting edge. The 40-degree helix angle promotes efficient chip evacuation, and the right-hand spiral flutes support consistent cutting direction in standard CNC and manual milling setups.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for ferrous and non-ferrous machining in job shop, toolroom, and production environments. The extra-long 6-inch overall length accommodates deep-cavity milling, pocket work, and contoured surface passes where standard-length tools cannot reach. The centercutting geometry allows plunge entry, making it useful for slotting, profiling, and ramping operations. Machinists and CNC programmers working with hardened steels, stainless alloys, and cast iron will find the TiCN coating and micrograin substrate well matched to those materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating extends tool life and reduces built-up edge in ferrous applications\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch corner radius reduces edge chipping and improves part surface finish at corners\u003c\/li\u003e\n  \u003cli\u003eExtra-long 6-inch OAL with 3-inch length of cut for deep-reach milling operations\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003e40-degree helix with right-hand spiral and right-hand cutting direction for standard spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/8-inch shank end mill compatible with ER, CAT, BT, and HSK toolholders sized for 5\/8-inch bore, used in CNC machining centers and manual knee mills with sufficient spindle speed and rigidity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the toolholder bore and collet are clean and within tolerance before seating the shank; shank diameter tolerance is -0.0001 to -0.0004 inches for a secure, concentric fit. Power down and lock out the spindle before changing tooling. Verify runout with a dial indicator after clamping to confirm concentricity before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches (1.2500 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.98 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: 12183347\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728682123570,"sku":"12183347","price":299.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33813fc6ddbf86859f42bbe2a5e2e2f2.jpg?v=1788694918","url":"https:\/\/voomisupply.com\/products\/accupro-12183347-corner-radius-end-mill-5-8-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
