The 3\/8-inch cutting diameter and 2-11\/16-inch overall length make it suited for slotting, profiling, and peripheral milling on milling machines and machining centers. The Weldon shank design provides positive drive and resistance to pullout under cutting loads. HSS construction delivers adequate toughness for general-purpose milling across a range of ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis end mill is used in job shop, production, and maintenance machining environments. It fits standard milling machine spindles and tool holders configured for Weldon shank tooling. Machinists and tool-and-die professionals reach for 4-flute end mills when finishing cuts and side milling are the primary operations. The 3\/8-inch diameter is a common size for slot and profile work on light to medium workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-flute geometry optimized for finishing and side milling passes\u003c\/li\u003e\n\u003cli\u003eWeldon shank design resists axial pullout under load\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides toughness across general-purpose materials\u003c\/li\u003e\n\u003cli\u003e3\/8-inch cutting diameter suits common slot and profile operations\u003c\/li\u003e\n\u003cli\u003e2-11\/16-inch overall length fits standard toolholder reach requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard Weldon shank end mill toolholders accepting a 3\/8-inch shank diameter in milling machines and machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist with the machine powered off and the spindle locked before tool changes. Seat the Weldon shank fully into the toolholder and tighten the set screw against the flat to the toolholder manufacturer's specified procedure. Inspect the cutting edges for chips or damage before each use, and confirm runout with a dial indicator when precision results are required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.375 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\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\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: 5110006\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51346355093810,"sku":"5110006","price":33.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538612.jpg?v=1782078169","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5110006-hss-end-mill-4-flute-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
