Built from M42 powdered metal, this stub-length tool features a titanium nitride (TiN) finish that extends tool life by reducing friction and heat buildup at the cutting edge. The 1\/8 inch diameter and matching 1\/8 inch straight cylindrical shank make it well suited for tight-tolerance slot milling, profiling, and light pocketing operations. A 37-degree helix angle promotes efficient chip evacuation. Center-cutting geometry allows plunge entry without a pre-drilled pilot hole. Installation is handled by machinists and toolroom technicians working on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use across several primary workpiece material categories including hardened steels, cast irons, stainless and heat-resistant alloys, carbon and alloy steels, and high-temperature superalloys. The PM-4 Series designation indicates a 4-flute powdered metal platform built for stability and consistent performance in these demanding materials. The right-hand cut and right-hand spiral flute configuration is standard for conventional and climb milling on most vertical machining setups. The stub length keeps deflection low when milling hard or tough materials at small diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8 inch mill diameter with 1\/4 inch length of cut for fine detail and slot work\u003c\/li\u003e\n\u003cli\u003eM42 powdered metal construction for toughness and wear resistance in difficult alloys\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces heat and friction, extending tool service life\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eStub length minimizes deflection at small diameter for improved accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank collet chucks and end mill holders accepting a 1\/8 inch shank.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware according to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a cut, particularly at this diameter where deflection sensitivity is highest.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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\u003eEnd Mill Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 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: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: PM-4\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: C31924\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695498985778,"sku":"C31924","price":76.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa33640b523fca82363dd563e9c3f391.jpg?v=1788335817","url":"https:\/\/voomisupply.com\/products\/cleveland-c31924-square-end-mill-1-8-in-4-flute-tin-pm-4","provider":"Voomi Supply","version":"1.0","type":"link"}
