It carries a 1 inch mill diameter, a 2 inch length of cut, and a 0.03 inch corner radius that reduces stress concentrations at the bottom of pocketing and profiling passes. The 7-flute geometry increases chip load capacity and improves surface finish at higher feed rates. An nACRo coating provides oxidation resistance and hardness retention at elevated cutting temperatures. This tool is a single-end, centercutting design with right-hand flute direction and right-hand cutting direction, making it suitable for standard CNC machining centers and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is used in precision machining environments where corner radii on pockets, slots, or contours must be held to tight tolerances. The variable index flute spacing helps suppress chatter during aggressive cuts in alloy steels, stainless steels, and hardened materials where micrograin carbide substrate and nACRo coating perform well. A 4 inch overall length and 1 inch shank diameter allow secure toolholder engagement with minimal overhang in most standard setups. It is sized for production work in job shops, tool rooms, and manufacturing cells running medium-to-large-diameter roughing and finishing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-flute design increases feed rate capability and improves surface finish in finishing passes\u003c\/li\u003e\n\u003cli\u003enACRo coating provides high hardness and oxidation resistance for cutting ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e0.03 inch corner radius reduces corner chipping and stress risers at the base of milled features\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter during heavy cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers consistent edge integrity and dimensional repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-procurement solid carbide corner radius end mill for CNC machining centers and manual mills accepting a 1 inch straight shank toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with end mill toolholding practices. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated in a clean, undamaged collet or end mill holder and torque the retention fastener per the toolholder manufacturer's specification. Inspect the cutting edges and corner radius under magnification before use to confirm no shipping damage is present.\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\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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: nACRo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002500 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: 1.64 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: 12177393\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748615160114,"sku":"12177393","price":390.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3afe3a774a0f60d94fb5dd29a8f0034a.jpg?v=1788895756","url":"https:\/\/voomisupply.com\/products\/accupro-12177393-corner-radius-end-mill-1in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
