Built around the KTFST series architecture, this drill accepts the KTFST06563HPL tip with KCMS15 grade solid carbide and an AlTiN PVD coating that provides heat and wear resistance at elevated cutting speeds. The cutting diameter is 0.6563 inches (17.00 mm) with a 140-degree drill point angle and a standard point type. Two helical flutes and through-coolant delivery keep the cutting zone clear and thermally controlled. The tip is held in place via a clamp mechanism using an HPL insert geometry with a U-seat. This tool is installed by machinists and tooling technicians in CNC drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip drill is suited for drilling stainless steel and other difficult-to-machine alloys classified under ISO material group M. Typical applications include straight drilling, inclined-exit drilling, and stacked-plate drilling. The through-coolant design supports higher feed rates and extended tip life in deep-hole and interrupted-cut scenarios where heat buildup and chip evacuation are primary concerns. The 2-flute, 2-margin configuration promotes hole straightness and surface finish quality in precision machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKCMS15 fine-grain solid carbide tip with AlTiN PVD coating for wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with standard point type for accurate entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design supports chip evacuation and thermal control during deep drilling\u003c\/li\u003e\n  \u003cli\u003eHPL insert geometry with U-seat and clamp holding for secure, repeatable tip positioning\u003c\/li\u003e\n  \u003cli\u003e2-flute helical regular spiral configuration optimized for stainless steel and ISO M materials\u003c\/li\u003e\n  \u003cli\u003eCompatible with inclined-exit and stacked-plate drilling operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KTFST series drill bodies accepting KTFST06563HPL replaceable tips and U insert seat size.

Ensure the insert seat is clean and free of chips before seating the tip and engaging the clamp. Through-coolant passages should be verified clear before operation. Follow the tool manufacturer and machine tool builder recommendations for speeds, feeds, and coolant pressure for the specific workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Inch)\u003c\/strong\u003e: 0.6563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter (mm)\u003c\/strong\u003e: 17.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCMS15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: AlTiN (PVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical, Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3282 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.4652 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: HPL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KTFST\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KTFST06563HPL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 6370918\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739700527410,"sku":"6370918","price":220.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5316861e4fa58b630d05fcee417e25f4_625a2c36-d4fa-4e87-b9f0-7e7040508c76.jpg?v=1788818006","url":"https:\/\/voomisupply.com\/products\/kennametal-6370918-carbide-replaceable-tip-drill-21-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
