Built from M42 cobalt steel, this single-end mill features a 3\/4-inch cutting diameter, a 1-5\/8-inch length of cut, and a 4-flute spiral configuration with a 30-degree helix angle. The right-hand cutting direction and right-hand flute geometry suit conventional and climb milling on ferrous materials, stainless steels, and harder alloys. The bright, uncoated finish is suitable for applications where a coating is not required or where regrinding will be performed. Machinists and toolroom operators working with manual mills or CNC machining centers will find this a solid general-purpose tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits standard applications in job shops, maintenance machining, and production environments where cobalt tooling is specified for its elevated hot hardness. The 1\/2-inch shank diameter accommodates common collet chucks and end mill holders found on Bridgeport-style knee mills and CNC vertical machining centers. The regular-length 3-5\/8-inch overall length provides good clearance for most standard workholding setups without excessive overhang. Center-cutting capability allows plunge entry, making it usable for slot milling, profiling, and pocket operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction for improved heat resistance over standard HSS end mills\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 30-degree helix angle for efficient chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry into workpieces\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 suitable for regrinding and general-purpose use\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 1\/2-inch shank for standard toolholding compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/2-inch collet chucks, end mill holders, and milling arbors on vertical knee mills, horizontal mills, and CNC machining centers.

Ensure the machine spindle is fully stopped and locked out before mounting or changing tooling. Seat the shank fully in the collet or holder to the recommended engagement depth and torque the drawbar or retention mechanism per the machine manufacturer specifications. Verify runout with a dial indicator before beginning a cut, and confirm workholding is secure before engaging the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches (3\/4 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\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches (1-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.625 inches (3-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches (1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VCCC-C-4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 723-3907\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714452095282,"sku":"723-3907","price":77.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0233d37243c2bb82a930af2ece973fa4.jpg?v=1788501656","url":"https:\/\/voomisupply.com\/products\/value-collection-723-3907-square-end-mill-3-4in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
