Built to the KC633M material grade and finished with a TiAlN coating, this single-end tool delivers heat and wear resistance suited to ferrous and difficult-to-machine materials. The 3-flute spiral geometry runs with a 30-degree helix angle, right-hand cut and right-hand flute orientation, and a centercutting design that allows both plunge and peripheral cutting. Installed by machinists and toolroom professionals, this end mill is a direct-fit solution for CNC machining centers and manual knee mills where tight tolerances are required.\u003c\/p\u003e\u003cp\u003eThis end mill is primarily intended for milling steel, stainless steel, and cast iron in production and job-shop environments. The 5\/32 inch diameter and 9\/16 inch length of cut make it appropriate for slot milling, profile milling, and finishing passes in small-feature workpieces. The 3\/16 inch shank fits standard collet systems at that size. It is a single-end tool, meaning it is replaced rather than flipped when worn, consistent with solid carbide end mill practice.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with KC633M material grade for rigidity and wear life\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal barrier and oxidation resistance in high-speed cutting\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design balances chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle reduces cutting forces on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute, compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard collet or end mill holders accepting a 3\/16 inch shank diameter.

Confirm spindle speed and feed rate are set according to the workpiece material and coating recommendations before engaging the cut. Do not run this tool without verifying shank seating depth and runout with a dial indicator, as carbide is brittle and sensitive to setup error. Coolant through is not supported on this tool; external coolant or air blast is appropriate depending on the material and operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: KC633M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3SE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.031 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6143943\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744962150706,"sku":"6143943","price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7397c69f4df5719569970a13ba36ae31_20032c21-a9ff-4228-8f4f-f901bfb3eb25.jpg?v=1788862770","url":"https:\/\/voomisupply.com\/products\/kennametal-6143943-square-end-mill-5-32-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
