It features a 3mm cutting diameter, a 4mm length of cut, and a 6mm shank diameter with a 50mm overall length. The three-flute spiral geometry with a 30-degree helix angle promotes efficient chip evacuation while maintaining rigidity in the cut. A TiAlN coating provides thermal resistance and extended tool life when machining ferrous and non-ferrous materials at elevated surface speeds. This is a single-end, right-hand cut, right-hand flute tool from the Kennametal KC633M grade in the 3CH-DKL series.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and finishing operations on steel, stainless steel, cast iron, and aluminum and non-ferrous materials. Its centercutting capability allows plunge entry, making it adaptable to pocketing and ramping applications. The metric-dimensioned shank fits standard ER collet chucks and end mill holders common in CNC machining centers and manual knee mills used in tool rooms and production shops. The compact 3mm diameter makes it particularly useful for detail work, small-feature milling, and tight-tolerance die and mold applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in KC633M grade for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for high-temperature performance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral design with 30-degree helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration\u003c\/li\u003e\n\u003cli\u003eMetric shank and dimensions; single-end design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard ER collet chucks and end mill holders accepting a 6mm metric shank diameter.

Seat the 6mm shank fully and evenly in the collet or holder and torque the retention nut to the toolholder manufacturer specification. Inspect the cutting edges and coating for chips or damage before each use. Follow the machine tool and toolholder manufacturer guidelines for runout tolerances and maximum RPM for this diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50mm (1.969 inches)\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\u003eSeries\u003c\/strong\u003e: 3CH-DKL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.055 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: 6146891\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728525099314,"sku":"6146891","price":79.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d51d4e1edbe37b5eeb0ac4204b6c3fcf.jpg?v=1788692701","url":"https:\/\/voomisupply.com\/products\/kennametal-6146891-square-end-mill-3mm-3-flute-tialn-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
