It features a 1\/4 inch cutting diameter, a 45-degree chamfer angle, and a 0.0100 inch chamfer width, delivering consistent edge geometry on hardened and difficult-to-machine workpieces. The AlTiN coating provides elevated heat resistance and extended tool life in high-speed dry or semi-dry cutting conditions. With a 4-flute, variable helix design and right-hand cutting direction, this end mill reduces chatter and improves surface finish. It is single-end with centercutting capability, allowing plunge entry where required. Typically installed by CNC machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for chamfering, edge prep, and countersinking operations on machining centers and CNC mills. The extended reach configuration, with a 2-1\/8 inch reach length and 4 inch overall length, makes it effective for accessing recessed features or working around fixturing. The 3\/8 inch length of cut handles standard chamfer depths in steel, stainless, cast iron, and high-temp alloys. The micrograin carbide substrate supports tight tolerances and resists edge wear in high-production runs. Shops running high-speed machining strategies benefit from the variable helix geometry, which dampens harmonics at elevated RPM.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree chamfer angle with 0.0100 inch chamfer width for consistent edge geometry\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for heat resistance and extended tool life in dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003eVariable helix, 4-flute spiral design reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for wear resistance and dimensional stability\u003c\/li\u003e\n\u003cli\u003eExtended reach design with 2-1\/8 inch reach length for deep or obstructed features\u003c\/li\u003e\n\u003cli\u003eCentercutting capable, right-hand cut, right-hand flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production end mill compatible with CNC machining centers and manual mills accepting a 1\/4 inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified CNC machinists or toolroom personnel. Secure the shank in a collet or end mill holder to the full depth of engagement and verify runout before beginning a cut. Confirm spindle speed and feed rate are appropriate for the workpiece material and coating type before engaging the cut. Never exceed the rated length of cut depth in a single pass without verifying rigidity and chip evacuation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\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: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 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: AlTiN\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\u003eHelix Style\u003c\/strong\u003e: Variable\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\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 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\u003eWeight\u003c\/strong\u003e: 0.3 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: 95168478\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730160714034,"sku":"95168478","price":117.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/abbbdf8d5d70cbdf2814822891ec032f.jpg?v=1788712771","url":"https:\/\/voomisupply.com\/products\/accupro-95168478-corner-chamfer-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
