Manufactured from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers improved wear resistance and extended tool life compared to uncoated HSS. The cutting diameter is 0.25 inches with a 0.625-inch length of cut and a 0.375-inch straight-cylindrical shank that also accepts a Weldon flat. Overall length is 3.375 inches. The 30-degree helix spiral flute geometry promotes efficient chip evacuation, and the centercutting configuration allows plunge entry directly into the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations on cast iron, non-ferrous metals, and steel in job shop, toolroom, and production environments. The double-end design provides two cutting ends on a single tool, reducing per-edge cost on repeat work. Right-hand cut and right-hand flute orientation are standard for conventional CNC and manual milling setups. The HD-4C series is a regular-length line intended for general-purpose slotting, profiling, and peripheral milling where extended reach is not required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25-inch cutting diameter with 0.625-inch length of cut for controlled depth engagement\u003c\/li\u003e\n  \u003cli\u003eTiN coating over HSS substrate improves surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eDouble-end design yields two usable cutting ends per tool\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flutes support chip flow and reduce heat buildup\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with Weldon flat option for secure collet or set-screw holder retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 0.375-inch ID collet chucks, ER collets, and Weldon-style end mill holders on CNC machining centers and manual knee mills.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the holder before tightening; if using a Weldon flat holder, align the set screw to the flat to prevent axial pullout under load. Verify runout with a dial indicator after installation and before initiating a 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\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/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\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/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\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eDouble End\u003c\/strong\u003e: Yes\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD-4C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, 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: C33067\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51710627250482,"sku":"C33067","price":70.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fad7f379d20d8d5aab9604b1bb601932.jpg?v=1788468877","url":"https:\/\/voomisupply.com\/products\/cleveland-c33067-square-end-mill-0-25-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
