Built to Series 133 standards, this 4-flute, double-end tool features a 3\/8 inch cutting diameter and a right-hand cutting direction. The bright\/uncoated finish suits general-purpose machining where coating buildup is a concern or re-sharpening is anticipated. With a 60-degree included angle and solid carbide construction, this mill delivers clean, accurate edge breaks and chamfers in production and job-shop environments alike. Machinists and CNC operators in metalworking and fabrication shops are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis chamfer mill is suited for use on vertical and horizontal machining centers, knee mills, and drill presses where chamfering, countersinking, or center-spotting operations are required. Its 3\/8 inch shank diameter fits standard collets and end mill holders commonly found in these machines. The 2-1\/2 inch overall length provides adequate reach for most standard workholding setups without introducing excessive overhang. The double-end geometry extends tool life by offering two usable cutting ends before the tool is retired or resharpened.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding machining applications\u003c\/li\u003e\n  \u003cli\u003e4-flute, double-end design provides efficient chip evacuation and extends usable tool life\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle for standard chamfering, countersinking, and spotting operations\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for general-purpose use and compatible with resharpening\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard CNC and manual spindle rotation\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch shank diameter fits common collets and end mill holders without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank chamfer mill compatible with 3\/8 inch collets and end mill holders on vertical machining centers, CNC mills, and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard tool-change procedures for the machine in use. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify that the collet or end mill holder is clean and free of chips before seating the shank, and torque the drawbar or collet nut to the machine manufacturer's specification. Confirm runout is within acceptable tolerance before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Head Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 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 Type\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 133\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Chamfering, Countersinking, Spotting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: PROMAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 133-02420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52076655804722,"sku":"133-02420","price":105.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/234f0650eecdddafad1c3eba66011d79.jpg?v=1790052821","url":"https:\/\/voomisupply.com\/products\/promax-133-02420-chamfer-mill-3-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
