It features a 1 inch cutting diameter, a 1.25 inch length of cut, and a 6 inch overall length with extended reach capability. The 3-flute, right-hand spiral geometry paired with a ZrN (zirconium nitride) coating delivers improved wear resistance and surface finish in ferrous and non-ferrous materials. A 37-degree variable-geometry helix promotes chip evacuation and reduces chatter. This tool is centercutting, allowing plunge entry into the workpiece. Machinists and CNC programmers working in job shop, aerospace, mold, and die environments will find this end mill suited for deep-reach finishing and semi-finishing operations.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where extended reach is required to access deep cavities, pockets, or contoured surfaces. The 3-3\/8 inch reach length and 0.95 inch neck diameter allow the cutter to clear workpiece walls without interference. The corner radius end type, with a 0.060 inch radius, reduces stress concentration at the cutting edge and produces a controlled blend radius at the floor-to-wall transition. Typical applications include mold cavities, die blocks, and structural aerospace components machined from alloy steels, stainless steels, and hardened materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch cutting diameter with 0.060 inch corner radius for controlled floor-to-wall blending\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention in hard materials\u003c\/li\u003e\n\u003cli\u003eZrN coating improves surface hardness and lubricity for extended tool life\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral geometry with 37-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eExtended reach design with 3.375 inch reach length and 0.95 inch neck diameter\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual milling machines with standard 1 inch toolholders or collet systems accepting a 1 inch shank diameter.

Secure the 1 inch straight shank in a precision collet, hydraulic chuck, or shrink-fit holder to minimize runout; excessive runout accelerates edge wear and reduces surface finish quality. Ensure the machine spindle is fully stopped and locked out before loading or removing the tool. Follow the toolholder manufacturer's torque specifications for set screws or clamping mechanisms, and verify tool projection length against programmed reach values before running the first cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 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: ZrN (Zirconium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eCentercutting\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00200 to -0.00200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.003000 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\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 315724\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748642849074,"sku":"315724","price":769.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a456c1bd729cbb15d37016d488fabeb.jpg?v=1788896091","url":"https:\/\/voomisupply.com\/products\/accupro-315724-corner-radius-end-mill-1-in-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
