Built from high speed steel (HSS) with a titanium nitride (TiN) finish, it offers improved wear resistance and extended tool life compared to uncoated HSS. The cutter measures 0.1875 inches in diameter with a 7\/16-inch length of cut and an overall length of 2-3\/8 inches. The 3\/8-inch straight-cylindrical shank with Weldon flat allows secure seating in standard end mill holders. A 30-degree helix angle promotes smooth chip evacuation across a range of materials and feed rates.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling in general machining environments. Its centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled hole. The regular-length configuration and compact 3\/16-inch diameter make it well-suited for finishing operations in tight pockets and confined features on ferrous and non-ferrous workpieces. It is part of the Cleveland HG-2 series, intended for productive material removal in job shop and production settings where HSS tooling is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiN coating over HSS substrate increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes efficient chip flow and reduces cutting force\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard milling spindle compatibility\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank with Weldon flat provides positive anti-pullout engagement in holders\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry delivers consistent finish on cast iron, non-ferrous metals, and steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard end mill holders and collet chucks accepting a 3\/8-inch straight shank with Weldon flat.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the holder and engage the set screw against the Weldon flat to prevent axial pullout under load. Verify runout with a dial indicator after clamping before beginning 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: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HG-2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\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: C41551\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697131258162,"sku":"C41551","price":46.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33a4cdd3f6053d7d8fe4a267fdb89d4c.jpg?v=1788349693","url":"https:\/\/voomisupply.com\/products\/cleveland-c41551-square-end-mill-3-16-in-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
