Built with four flutes and a 40-degree helix angle, this tool delivers aggressive material removal while maintaining surface finish quality in a single setup. The chipbreaker geometry reduces cutting forces and aids chip evacuation during extended cuts. At 1 inch in diameter with a 2.25-inch length of cut, it is well suited for full-depth slotting, profiling, and pocket milling in ferrous and non-ferrous materials. This is a single-end, right-hand cut, right-hand flute tool with an uncoated carbide substrate.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in production and job-shop environments where a single tool must handle both stock removal and finish passes. The long-length configuration with a 5-inch overall length allows access to deeper features and cavities. It is installed by machinists and toolroom technicians in standard ER collet chucks, end mill holders, or hydraulic tool holders with a 1-inch bore. Applications include mold work, fixture machining, and general-purpose profiling in steel, cast iron, aluminum, and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003e4-flute design balances chip clearance with surface finish capability\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle reduces cutting forces and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eChipbreaker geometry aids chip control during deep roughing passes\u003c\/li\u003e\n  \u003cli\u003eLong-length configuration reaches deeper pockets and cavities\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cut with square end profile for sharp corner milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1-inch-bore end mill holders, ER collet chucks, and hydraulic tool holders on CNC machining centers and manual knee mills requiring a long-length, 4-flute square carbide end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Secure the shank fully within the tool holder to the manufacturer-recommended minimum engagement depth before tightening. Verify tool runout with a dial indicator before initiating the first cut. Always power down and lock out the spindle before changing tooling, following applicable machine safety procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Square\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Type\u003c\/strong\u003e: Non-Extended Reach\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdditional Features\u003c\/strong\u003e: Chipbreaker, Long Length\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.888 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12185442\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732596359474,"sku":"12185442","price":604.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eac11062750701b0e12c06452dc6f678.jpg?v=1788744824","url":"https:\/\/voomisupply.com\/products\/accupro-12185442-square-end-mill-1-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
