Built from M42 cobalt high-speed steel with a TiCN coating, it delivers enhanced wear resistance and heat tolerance compared to standard HSS tooling. The cutter measures 3\/8 inch in diameter with a 3\/4 inch length of cut and a 2.5 inch overall length. Four flutes and a right-hand cutting direction make it suited for conventional roughing passes on ferrous and non-ferrous workpiece materials. Machinists and tool-and-die professionals install this end mill in manual or CNC milling machines where stock removal rate is the primary goal.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is intended for use in shop environments where material is being hogged out prior to a finishing pass. The 3\/8 inch shank seats directly into standard collets or end mill holders of matching bore. Its non-centercutting geometry means it is not designed for plunge cutting. Typical applications include profiling, slotting, and peripheral roughing in steel, stainless, and similar materials where cobalt tooling provides an advantage over standard M2 HSS.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction provides increased red hardness and tool life in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends edge life compared to uncoated tooling\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch diameter with matching 3\/8 inch shank for direct collet or holder mounting\u003c\/li\u003e\n  \u003cli\u003e4-flute geometry balances chip evacuation with rigidity for roughing passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard milling setups\u003c\/li\u003e\n  \u003cli\u003eSingle-end design; non-centercutting, not rated for plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/8 inch collets or end mill holders on manual knee mills and CNC machining centers.

Ensure the spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Seat the shank to the recommended engagement depth in the collet or holder and torque the retention mechanism per the toolholder manufacturer's specification. Because this is a non-centercutting tool, do not program or attempt direct axial plunge moves into solid material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.504 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84511815\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731928318258,"sku":"84511815","price":53.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/290341ee1369fa9d50a064a647cba447.jpg?v=1788736749","url":"https:\/\/voomisupply.com\/products\/hertel-84511815-roughing-end-mill-3-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
