Built from M42 cobalt high-speed steel, it delivers strong heat and wear resistance in tough-to-machine materials. The mill measures 1.75 inches in diameter with a 0.75-inch shank diameter, a 2-inch length of cut, and a 4.25-inch overall length. Six flutes with a right-hand cutting and flute direction provide fast stock removal with good chip clearance. The bright, uncoated finish suits general-purpose roughing applications. This tool is used by machinists and tool-and-die professionals working on manual or CNC milling machines.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for roughing passes on ferrous and non-ferrous metals where high material removal rates are the priority. The cobalt M42 substrate makes it a practical choice for harder alloys, stainless steels, and work-hardening materials that would accelerate wear on standard high-speed steel tooling. The single-end configuration and non-centercutting geometry mean it is intended for side milling, slotting from an existing hole, or profile passes rather than direct plunge entry. It fits standard 3\/4-inch collets or end mill holders common on knee mills and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for improved heat resistance and tool life in difficult materials\u003c\/li\u003e\n\u003cli\u003e1.75-inch cutting diameter with a 2-inch length of cut for substantial depth-of-cut capability\u003c\/li\u003e\n\u003cli\u003e6-flute geometry optimized for high material removal rates on roughing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating buildup to affect dimensional tolerances\u003c\/li\u003e\n\u003cli\u003eNon-centercutting design; requires a pre-drilled or pre-milled entry point for plunge applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/4-inch end mill holders or collet chucks on manual knee mills, horizontal mills, and CNC machining centers requiring a single-end roughing tool in the 1-3\/4-inch diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully in a clean, undamaged end mill holder or collet to the holder manufacturer's specified clamping depth before engaging the spindle. Verify spindle direction is set to right-hand rotation before running. Because this tool is non-centercutting, do not attempt direct plunge cuts into solid material without a pre-existing entry hole or ramping toolpath.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 723-5877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694665597234,"sku":"723-5877","price":319.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2454ccbe14fad9b466c198623906797c.jpg?v=1788326879","url":"https:\/\/voomisupply.com\/products\/value-collection-723-5877-roughing-end-mill-1-3-4-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
