Built on the H1TE series platform, this single-end tool features a 10.00 mm (0.3937 inches) cutting diameter and a matching 10.00 mm shank diameter, making it a straight-shank configuration ready for standard collet or end mill holders. The 4-flute geometry with a variable helix angle of 36 to 39 degrees reduces chatter and improves surface finish at higher feed rates. An AlTiN coating provides thermal resistance and extended tool life when cutting ferrous and difficult-to-machine alloys. Material grade KCPM15 is the substrate designation. This tool is installed by machinists and CNC programmers working in job shop, production, and aerospace environments.\u003c\/p\u003e\n\u003cp\u003eThe 6769564 is rated for steel, stainless steel, cast iron, high-temperature alloys, and hardened materials, covering ISO material codes P, M, K, S, and H. The 22.00 mm length of cut and 30.00 mm reach length suit both shallow and extended-reach operations. The extended reach design makes it suitable for pocketing and profiling where a longer tool hang is required. Variable index spacing between flutes reduces harmonic vibration, which is especially useful when machining thin-walled workpieces or high-strength alloys at aggressive parameters. Centercutting capability allows plunge entry directly into the workpiece. Coolant-through is not supported on this tool; external flood or mist coolant should be used instead.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with AlTiN coating for heat and wear resistance in ferrous and high-temp alloy cutting\u003c\/li\u003e\n  \u003cli\u003eVariable helix (36-39 degrees) and variable index geometry reduce vibration and chatter\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eExtended reach length of 30.00 mm supports deeper pocket and profile operations\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cut with right-hand spiral flutes; compatible with standard right-hand spindles\u003c\/li\u003e\n  \u003cli\u003eKCPM15 substrate optimized for toughness and wear resistance across multiple workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with steel, stainless steel, cast iron, high-temperature alloys, and hardened materials (ISO codes P, M, K, S, H).

Ensure the machine spindle is fully stopped and the tool is secured in a clean, properly sized collet or holder before engaging the drawbar or clamping mechanism. Confirm runout at the tool tip before beginning a production cut, as excessive runout accelerates edge wear on variable-helix tools. Because coolant-through is not supported, set up external flood or mist coolant directed at the cutting zone to manage heat and chip evacuation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 22.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 30.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 72.00 mm (approximately 2.83 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36-39 degrees (variable)\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: KCPM15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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 Spiral\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel; Stainless Steel; Cast Iron; High-Temp Alloy; Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H1TE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.13 inches L x 0.79 inches W x 0.79 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6769564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743741444402,"sku":"6769564","price":200.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45b8aefafd7ef95506c45acae2c3ea20_45072901-6d1e-4243-a4e1-783ada4605ae.jpg?v=1788849454","url":"https:\/\/voomisupply.com\/products\/kennametal-6769564-square-end-mill-0-3937in-4-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
