Featuring a Weldon shank for positive tool holding and a 4-flute geometry, this end mill delivers clean cutting action and dimensional stability under load. The 3\/8 inch tip diameter and 2.5 inch overall length make it well suited for slot milling, profiling, and peripheral cuts on ferrous and non-ferrous materials. HSS construction provides toughness and resistance to chipping in interrupted cuts where carbide tooling may be less forgiving.\u003c\/p\u003e\n\u003cp\u003eThis end mill is a practical choice for machinists, maintenance mechanics, and trade professionals performing manual or CNC milling work on steel, aluminum, brass, and similar materials. The 4-flute design improves surface finish and feed rate capability compared to 2-flute variants, making it appropriate for finishing passes and general-purpose material removal in production or job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel (HSS) construction for toughness in interrupted and general-purpose cuts\u003c\/li\u003e\n  \u003cli\u003eWeldon shank design provides a secure, slip-resistant tool holding interface\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry supports improved surface finish and higher feed rates\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch tip diameter suitable for slot milling, profiling, and peripheral operations\u003c\/li\u003e\n  \u003cli\u003e2.5 inch overall length fits standard milling setups without excessive overhang\u003c\/li\u003e\n  \u003cli\u003eSold individually — single-piece unit of measure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use HSS end mill compatible with standard Weldon-shank milling tool holders accepting a 3\/8 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or trained maintenance technician. Ensure the milling machine spindle is fully stopped and locked out before seating or removing the end mill from the tool holder. Tighten the Weldon shank set screw to the tool holder manufacturer's specification to prevent axial pullout during operation. Inspect the cutting edges for chipping or wear before each use and replace the tool if damage is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eTip Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5110005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51346142462258,"sku":"5110005","price":26.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538625.jpg?v=1782071948","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5110005-hss-end-mill-4-flute-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
