Featuring a Weldon shank and 4-flute geometry, this end mill delivers controlled chip evacuation and surface finish quality suited to ferrous and non-ferrous materials. The cutting diameter is 1\/2 inch with an overall flute length of 2-11\/16 inches. HSS construction provides toughness and resistance to fracture under interrupted cuts, making it a reliable choice for job shops and maintenance machinists working on manual or CNC milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose milling tasks including slotting, profiling, and peripheral cutting. The Weldon shank design provides positive clamping in set-screw style end mill holders, reducing the risk of pullout under load. The 4-flute configuration makes it appropriate for finish milling passes and side milling in steel, aluminum, and similar materials where chip clearance is not the primary constraint.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-speed steel (HSS) construction for toughness and impact resistance\u003c\/li\u003e\n\u003cli\u003eWeldon shank for positive retention in set-screw end mill holders\u003c\/li\u003e\n\u003cli\u003e4-flute geometry suited to finish milling and side milling operations\u003c\/li\u003e\n\u003cli\u003e1\/2 inch cutting diameter for common slot and profile work\u003c\/li\u003e\n\u003cli\u003e2-11\/16 inch overall length accommodates standard milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose HSS end mill compatible with standard Weldon shank end mill holders sized for 1\/2 inch shank tooling on manual and CNC knee mills, bed mills, and machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Secure the Weldon shank firmly in the end mill holder using the set-screw against the flat, and verify runout before cutting. Always de-energize and lock out the spindle before changing tooling. Follow machine manufacturer guidelines and applicable shop safety standards for speeds, feeds, and workholding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-11\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5110007\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51343945990450,"sku":"5110007","price":33.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538611.jpg?v=1782025909","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5110007-hss-end-mill-4-flute-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
