Built from solid carbide with a TiCN (titanium carbonitride) coating, it delivers hardness and heat resistance well suited to production environments. The 1\/4 inch diameter cutter runs 4 flutes in a coarse-pitch configuration with a 30-degree maximum helix angle, enabling fast chip evacuation and reduced chatter during heavy cuts. This tool is center-cutting, so it can plunge directly into material without a pre-drilled entry point. Machinists and toolroom professionals install this end mill for roughing passes where stock removal rate matters more than surface finish.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers, knee mills, and manual milling machines where a 1\/4 inch shank is appropriate. The coarse pitch is particularly effective when cutting softer steels, aluminum, and similar materials at higher feed rates. With a 3\/8 inch length of cut and 2 inch overall length, it fits compact workholding setups and close-quarter milling situations. Right-hand cutting and right-hand flute direction are standard for conventional spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003eCoarse pitch, 4-flute design promotes aggressive chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003e30-degree maximum helix angle balances cutting action and stability\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4 inch shank roughing end mill compatible with collet chucks, end mill holders, and other 1\/4 inch tool-holding systems used in CNC and manual milling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eEnd mills are installed by a machinist or toolroom technician using an appropriate collet or end mill holder rated for the shank diameter. Power down and lock out the spindle before changing tooling. Verify runout after seating the tool in the holder, and confirm shank engagement depth meets the holder manufacturer's minimum specification. Shank diameter tolerance on this tool is -0.0001 to -0.0004 inches, so select a collet size accordingly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.25 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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.005000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 100\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: PROMAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100-01622\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52066813346098,"sku":"100-01622","price":94.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00ce2d56ff976d90936bda504a38fc20.jpg?v=1790045817","url":"https:\/\/voomisupply.com\/products\/promax-100-01622-roughing-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
