Built from M42 cobalt high-speed steel and finished with a TiCN coating, it delivers extended tool life in abrasive and heat-generating cuts. The 4-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 5\/16 inch in diameter with a 2-inch length of cut and 3-3\/4 inch overall length, this is an extra-long geometry suited to reaching deep features without repositioning the workpiece. Machinists and toolroom technicians install this tool in standard CNC machining centers and manual knee mills.\u003c\/p\u003e\u003cp\u003eThe C32720 is rated for use on high temperature alloys, stainless steel, and steel. The centercutting design allows plunge entry, expanding its utility in slot milling, profiling, and pocket operations where a ramp or drill entry is not practical. The 3\/8 inch straight-cylindrical shank with a Weldon flat accepts standard ER collet chucks and side-lock holders, making it straightforward to set up in common toolholding systems found on most shop floors. The extra-long length of cut range supports deep slot work and extended-reach applications that standard-length end mills cannot reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat and wear resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in stainless steel and high-temperature alloy cuts\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral with 30-degree helix for balanced chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eExtra-long 2-inch length of cut for deep slot and pocket applications\u003c\/li\u003e\n\u003cli\u003e3\/8 inch Weldon flat shank for secure toolholding in side-lock and collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual milling machines accepting a 3\/8 inch straight-cylindrical or Weldon flat shank.

Secure the Weldon flat shank in a properly torqued side-lock holder or collet chuck rated for the shank diameter before mounting in the spindle. Confirm spindle speed and feed rate are set for the workpiece material and tool diameter before engaging the cut. Do not exceed the rated length of cut depth in a single pass without verifying deflection limits for the application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 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\u003eMaterial Finish\u003c\/strong\u003e: TiCN\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\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical with Weldon Flat\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: High Temperature Alloy, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HGC-4C\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: C32720\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51722807214386,"sku":"C32720","price":80.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe85c5bd49d5f56978a7131aae676a29.jpg?v=1788596193","url":"https:\/\/voomisupply.com\/products\/cleveland-c32720-square-end-mill-5-16-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
