Built from high speed steel with a titanium nitride (TiN) finish, it offers improved surface hardness and wear resistance over uncoated HSS tooling. The 1-inch diameter cutting end pairs with a 1-inch straight-cylindrical shank with Weldon flat, delivering secure tool holding in standard end mill holders. Four spiral flutes at a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. With a 1-7\/8-inch length of cut and 6-3\/8-inch overall length, this is a regular-length tool suited for slots, pockets, and peripheral milling on ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003cp\u003eThis end mill is rated for primary workpiece materials including steel, cast iron, and non-ferrous metals, covering a wide range of common machining tasks. The double-end configuration provides two usable cutting ends per tool, extending effective tool life before replacement is needed. Right-hand cut and right-hand flute geometry are standard for conventional milling setups. Typical users include CNC machinists, manual mill operators, tool-and-die shops, and maintenance machining operations where a reliable HSS end mill is preferred over carbide in interrupted-cut or vibration-prone setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends per tool for extended use\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces tool wear compared to bare HSS\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle with spiral flutes aids chip flow and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eWeldon flat on straight-cylindrical shank prevents tool pull-out in side-lock holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1-inch end mill holders, side-lock holders with Weldon flat, or collet chucks accepting a 1-inch shank diameter.

Ensure the spindle is fully powered down and the machine is locked out before changing tooling. Seat the Weldon flat against the set screw in side-lock holders to prevent axial pullout under load. Verify runout with a dial indicator after tool installation before taking cuts, particularly for close-tolerance work.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch (1.0000 inch decimal \/ 25.40 mm)\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\u003eFinish\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-7\/8 inches (1.8750 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch (1.0000 inch decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-3\/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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical with Weldon Flat\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\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: C33099\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693890666802,"sku":"C33099","price":269.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9d7cb880c7910c4c7f20db2039b6268.jpg?v=1788318647","url":"https:\/\/voomisupply.com\/products\/cleveland-c33099-square-end-mill-1-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
