Built from M42 cobalt high-speed steel, it delivers superior heat resistance and edge retention compared to standard HSS tooling. The cutter features a 0.25-inch mill diameter, a 0.5-inch length of cut, and a 30-degree helix angle with spiral fluting. It is centercutting, allowing direct plunging into a workpiece. This tool is intended for use by machinists and tool-and-die professionals on manual mills, CNC mills, and machining centers where consistent finish and tool life in hard materials are priorities.\u003c\/p\u003e\u003cp\u003eThe C42607 is suited for milling high-temperature alloys, stainless steel, and steel. Its 3\/8-inch straight-cylindrical or Weldon flat shank provides secure holding in standard end mill holders, collet chucks, and Weldon-style set-screw holders. The regular-length geometry and 2-flute design promote chip evacuation in slotting and side-milling operations. It is a strong choice for shops running aerospace, medical, or general precision-machining work where stainless and high-temp alloys are common workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat resistance and extended tool life in tough materials\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e2-flute configuration optimized for slotting and full-width cuts in harder alloys\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute with uncoated finish\u003c\/li\u003e\n\u003cli\u003eAccepts standard Weldon flat or straight-cylindrical end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3\/8-inch end mill holders, collet chucks, and Weldon flat holders on manual and CNC milling machines.

Ensure the spindle is fully powered down and at rest before inserting or removing the end mill. Confirm the shank is clean and fully seated to the minimum insertion depth recommended by the holder manufacturer before tightening set screws or collet nut. Do not exceed the tool's rated length-of-cut range when programming axial depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.5 to 0.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 grade)\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical \/ Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: HGC-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: High Temperature Alloy, Stainless Steel, Steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C42607\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693152567602,"sku":"C42607","price":39.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/180af8c100ddd978ae7883f5b299d46a.jpg?v=1788308080","url":"https:\/\/voomisupply.com\/products\/cleveland-c42607-square-end-mill-0-25-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
