Designed for precision hole-making in steel and cast iron, this drill accepts a solid carbide insert held by a clamp-style seat and delivers consistent performance in demanding metal-cutting environments. The 14.6mm (0.5748 inch) cutting diameter, 2-flute helical configuration, and HPG insert geometry combine to support accurate entry and chip evacuation. Machinists and tooling technicians working in production or job-shop environments are the primary users of this tooling system.\u003c\/p\u003e\u003cp\u003eThis replaceable tip drill is suited for drilling applications in ferrous materials, including steel and cast iron, across both production machining and general metalworking environments. Its KTFS series design supports inclined exit drilling and stacked plate drilling in addition to standard through and blind-hole operations. The standard spiral and 2-flute, 2-margin configuration makes it effective for maintaining hole quality in interrupted or variable-entry cuts. No internal coolant delivery is available with this configuration, so external or flood coolant is recommended for heat management in extended drilling cycles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide KCP15A grade tip with fine grain material for wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for improved heat resistance and tool life in ferrous cutting\u003c\/li\u003e\n\u003cli\u003eHPG insert geometry with clamp-type holding for secure, repeatable tip seating\u003c\/li\u003e\n\u003cli\u003e2-flute helical design with 2-margin construction for accurate hole geometry\u003c\/li\u003e\n\u003cli\u003eSupports inclined exit, stacked plate, and standard drilling applications\u003c\/li\u003e\n\u003cli\u003eReplaceable tip design reduces tooling cost compared to solid carbide drills\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the KTFS series replaceable tip drill system.

Ensure the spindle is fully stopped and the machine is locked out before changing the replaceable tip. Use the correct torque tool specified by the toolholder manufacturer for the clamp screw  -  do not overtighten or use impact tools. Verify runout and tip seating before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 14.6mm (0.5748 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCP15A\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KTFSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: HPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: S\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 10.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.2874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.4118 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P, K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KTFSS14600HPGM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.028 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: 6388793\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743940215090,"sku":"6388793","price":161.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6347f7cd35a09a3bd394746d06feef03_c229f3c4-3ef6-47da-b8a8-0eb4f39e2a35.jpg?v=1788851625","url":"https:\/\/voomisupply.com\/products\/kennametal-6388793-carbide-replaceable-tip-drill-14-6mm","provider":"Voomi Supply","version":"1.0","type":"link"}
