Manufactured from M42 cobalt high-speed steel, it delivers the heat and wear resistance needed when machining tough workpieces that would prematurely dull standard HSS tooling. The double-end design provides two usable cutting ends, extending tool life on the shop floor. A TiN (titanium nitride) coating further improves surface hardness and lubricity at the cutting edge. With a 0.25-inch diameter, 4-flute geometry, and a 30-degree helix angle, the C32949 is suited for finishing and light roughing passes where chip evacuation and edge quality both matter.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use in vertical machining centers, knee mills, and manual milling machines where a 0.375-inch straight shank is compatible with the spindle or toolholder. The 0.625-inch length of cut accommodates standard-depth slotting, peripheral milling, and profiling operations. Right-hand cut and right-hand spiral flutes are standard for conventional milling setups. The centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled pilot hole. It is primarily applied in job shops, tool rooms, and production environments machining aerospace-grade alloys, die steels, and austenitic stainless grades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction resists heat buildup when cutting high-temperature alloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool, reducing per-edge tooling cost\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree spiral flute helix balances chip evacuation with edge strength on 4-flute layout\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with Weldon flat accommodates standard side-lock and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in milling machines and machining centers accepting a 0.375-inch straight shank with Weldon flat.

Seat the Weldon flat securely against the set screw in the toolholder to prevent pull-out under axial cutting loads. Verify runout with a dial indicator after mounting, as excessive runout accelerates flute wear on small-diameter end mills. Follow the machine manufacturer and cutting tool manufacturer feed and speed recommendations for the specific workpiece material before beginning the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\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: 3.375 inches (3-3\/8 inches)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical with Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble End\u003c\/strong\u003e: Yes\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: HDC-4C\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: C32949\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51716014965042,"sku":"C32949","price":64.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f4000eb27645c811d0f822eb01d8632.jpg?v=1788521009","url":"https:\/\/voomisupply.com\/products\/cleveland-c32949-square-end-mill-0-25-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
