It carries a 3\/8 inch cutting diameter with a 3\/4 inch length of cut and a 2-1\/2 inch overall length. The straight cylindrical shank with Weldon flat measures 3\/8 inch in diameter for secure tool holding in standard end mill holders. A 42-degree helix angle promotes efficient chip evacuation, while the spiral flute geometry and right-hand cut with right-hand flute configuration are suited to general-purpose milling applications where consistent chip flow is required. The tool is uncoated and centercutting, allowing plunge entry into the workpiece.\u003c\/p\u003e\u003cp\u003eThe C40072 belongs to the Cleveland PM-539R series, intended for machining non-ferrous metals such as aluminum, brass, copper, and plastics. Its regular-length geometry fits standard vertical and horizontal milling setups in job shops, production environments, and maintenance machining. The centercutting design allows both peripheral and plunge cuts, giving machinists flexibility in slotting, profiling, and pocketing operations. Shank compatibility with standard R8, ER collet, and Weldon-style tool holders makes setup straightforward on most knee mills and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch cutting diameter with 3\/4 inch length of cut for precise slot and profile work\u003c\/li\u003e\n\u003cli\u003ePowdered metal construction provides consistent hardness and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003e42-degree helix angle supports efficient chip evacuation in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute spiral configuration for standard spindle use\u003c\/li\u003e\n\u003cli\u003eWeldon flat on straight cylindrical shank reduces slippage under load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the Cleveland PM-539R series.

Ensure the spindle is fully stopped and the machine is powered down before loading or changing tooling. Verify tool holder runout with a dial indicator before beginning cuts, as excessive runout accelerates wear on powdered metal tooling. Consult the machine manufacturer guidelines and applicable shop standards for proper clamping torque on set screws used with Weldon flat holders.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 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\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 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\u003eEnd Mill Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: PM-539R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\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: C40072\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693445873970,"sku":"C40072","price":86.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55bc58d72a24db061c802db9d3a0c06f.jpg?v=1788312471","url":"https:\/\/voomisupply.com\/products\/cleveland-c40072-square-end-mill-3-8-in-3-flute-powdered-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
