Manufactured from M42 cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard HSS tooling. The 4-flute geometry produces a coarse chip-breaking action that reduces cutting forces and heat buildup during heavy cuts. With a 0.625-inch cutting diameter, a 2.5-inch length of cut, and an overall length of 4.625 inches, this end mill suits roughing passes on steel, stainless, and other ferrous materials in both manual and CNC milling setups. The bright, uncoated finish is standard for cobalt tooling used across general-purpose roughing work.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for side milling, slotting, and profiling operations where rapid stock removal is the priority before a finishing pass. The right-hand cutting direction and right-hand flute helix are compatible with standard vertical and horizontal milling machines as well as CNC machining centers. It is not centercutting, so plunge cuts are not recommended. Machinists in job shops, maintenance facilities, and production environments regularly use this type of tooling on ferrous and harder non-ferrous workpieces where cobalt-grade heat resistance is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for elevated heat and abrasion resistance\u003c\/li\u003e\n\u003cli\u003e4-flute design promotes efficient chip evacuation and smooth surface finish on roughing passes\u003c\/li\u003e\n\u003cli\u003e0.625-inch cutting diameter with matching 0.625-inch shank diameter for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003cli\u003e2.5-inch length of cut accommodates moderate-depth roughing operations\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for use in standard milling setups\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating to delaminate on regrind cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose roughing end mill for use in standard R8, CAT, BT, or HSK toolholding systems accepting a 0.625-inch shank diameter.

Ensure the milling machine spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended insertion depth in the end mill holder or collet to prevent tool pullout under cutting loads. This tool is not centercutting — avoid programming plunge moves directly into the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.625 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 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 724-2155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690543710514,"sku":"724-2155","price":87.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e7f0f8ee7ebd93e85e0c279844aa82d.jpg?v=1788271350","url":"https:\/\/voomisupply.com\/products\/value-collection-724-2155-roughing-end-mill-0-625-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
