Ground from high speed steel and finished with a titanium carbonitride (TiCN) coating, this tool runs in right-hand rotation with right-hand spiral flutes at a 30-degree helix angle. The centercutting geometry allows plunge entry as well as peripheral milling. With a 25\/64-inch cutting diameter and 4 flutes, it delivers a balance of chip clearance and surface finish suitable for slotting, profiling, and pocketing operations. Machinists and tool-and-die professionals are the primary users of this type of end mill.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard knee mills, CNC machining centers, and manual milling machines equipped with a 1\/2-inch collet or end mill holder. The 1-inch length of cut accommodates moderate-depth passes, while the 4-1\/2-inch overall length provides sufficient clearance in most vertical and horizontal setups. The double-end design extends tool life by offering two usable cutting ends before the tool is retired. It is suited to production and maintenance machining environments where consistent tolerances are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating increases surface hardness and lubricity compared to uncoated HSS, extending tool life in abrasive cuts\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduces chatter during peripheral milling\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends per tool, improving cost efficiency\u003c\/li\u003e\n\u003cli\u003e4-flute configuration balances material removal rate with surface finish quality\u003c\/li\u003e\n\u003cli\u003eSeries HD-4C construction with regular length-of-cut classification for standard milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any milling machine or machining center equipped with a 1\/2-inch collet, end mill holder, or ER-style chuck.

Use a properly sized collet or end mill holder torqued to the machine manufacturer's specification — do not rely on visual seating alone. Inspect the shank for wear or fretting before mounting, and confirm runout with a dial indicator after clamping when tight tolerances are required. Follow applicable shop safety procedures and machine guarding requirements during all operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 25\/64 inch (0.3906 inches)\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: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/2 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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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\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: C33117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51704930206002,"sku":"C33117","price":78.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ccc3ef17efa09165200daa649842abe1_098ca55e-0a54-4796-9257-ba06de10acc1.jpg?v=1788425829","url":"https:\/\/voomisupply.com\/products\/cleveland-c33117-square-end-mill-25-64-in-4-flute-hss-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
