It features a 1 inch cutting diameter, a 3 inch length of cut, and a 6 inch overall length. The three-flute, right-hand spiral geometry runs at a 37-degree helix angle, promoting efficient chip evacuation and reduced cutting forces. A zirconium nitride (ZrN) coating improves surface hardness and heat resistance, extending tool life in demanding cutting conditions. The micrograin carbide substrate provides the rigidity and edge retention required for consistent dimensional accuracy across production runs.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations in job shops, tool rooms, and production machining environments. It is a center-cutting tool, allowing direct plunge entry as well as conventional side milling and slotting. The 1 inch shank diameter accommodates standard end mill holders and collet chucks. It is appropriate for use on CNC machining centers and manual knee mills where a 1 inch tool is specified. The right-hand cutting direction is compatible with standard spindle rotation on most vertical and horizontal machining platforms.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch cutting diameter with a mill diameter tolerance of +0.000 \/ -0.005 inches for consistent fitment\u003c\/li\u003e\n\u003cli\u003e3 inch length of cut supports deep-pocket and full-depth side milling applications\u003c\/li\u003e\n\u003cli\u003e3-flute, right-hand spiral geometry at 37-degree helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eZrN coating increases surface hardness and thermal resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction delivers rigidity and sharp edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1 inch end mill holders and collet chucks on CNC machining centers and manual mills requiring a 1 inch shank, single-end square end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with tool holding standards and safe tooling practices. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool. Seat the shank to the recommended engagement depth specified by the tool holder manufacturer and torque set screws or collet nuts per the holder manufacturer guidelines. Inspect the cutting edges and coating for damage before each use and replace the tool if chipping or excessive wear is observed.\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.005 inches\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: 3 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute 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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.4 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: 315086\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739440251186,"sku":"315086","price":637.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5f4c57e8ecb4415aeb47b1113c905cf.jpg?v=1788814613","url":"https:\/\/voomisupply.com\/products\/accupro-315086-square-end-mill-1-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
