Built from micrograin solid carbide and coated with AlCrTiN for heat and wear resistance, this tool delivers consistent performance in hardened and abrasive materials. It features a 1\/4 inch mill diameter, a 3\/8 inch length of cut, and a 4 inch overall length. The 5-flute, right-hand spiral geometry with a 38-degree helix and variable index promotes smooth chip evacuation and reduces chatter. Centercutting capability allows plunge entry, adding flexibility across a range of milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in vertical machining centers and CNC milling setups where extended reach is required. The extended reach design with a 3\/4 inch reach length and reduced neck diameter of 0.237 inches allows access to deep pockets and profiled features without interference. The 0.010 inch corner radius protects the cutting edge and reduces stress concentrations at the tool tip, making it appropriate for finishing passes on molds, dies, and precision components in both job shop and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlCrTiN coating for elevated heat resistance and extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e5-flute variable index design reduces vibration and improves surface finish\u003c\/li\u003e\n\u003cli\u003e0.010 inch corner radius protects cutting edge and reduces tip chipping\u003c\/li\u003e\n\u003cli\u003eExtended reach with 3\/4 inch reach length and reduced neck for deep-pocket access\u003c\/li\u003e\n\u003cli\u003eCentercutting construction allows direct plunge milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tool for standard 1\/4 inch collet or end mill holders on CNC vertical machining centers and manual mills equipped with appropriate tooling systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and locked out before mounting or removing the end mill. Seat the shank fully and evenly in a clean, undamaged collet or end mill holder and torque the retention nut to the machine or toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use and do not exceed the recommended depth of cut for the tool diameter and workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches (101.6 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.237 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\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\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\u003eChipbreaker\u003c\/strong\u003e: No\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\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\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: 312075\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748226466098,"sku":"312075","price":80.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c392e16ab69808c56a5f572a5762aa1.jpg?v=1788890663","url":"https:\/\/voomisupply.com\/products\/accupro-312075-corner-radius-end-mill-1-4-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
