The drill body accepts a solid carbide KTFSS-series tip with a KCP15A grade insert and HPG geometry, secured by a clamp-style holding method. An AlTiN coating applied via PVD process provides thermal resistance and wear protection during aggressive drilling cycles. The cutting diameter is 16.1mm (0.6339 inches), with a flute length of 8.0mm and an overall projection of 0.4548 inches. Two helical flutes with a regular spiral promote chip evacuation. This tool is suited for CNC machining centers and production drilling environments where replaceable-tip systems reduce tooling cost per hole.\u003c\/p\u003e\u003cp\u003eThis replaceable-tip drill is used in production machining of steel and cast iron components, including structural parts, housings, and fabricated assemblies. It is engineered to handle demanding applications including drilling through inclined exit surfaces and stacked plates  -  conditions that challenge standard drill geometries. The KTFS series platform allows tip replacement without removing the shank body, reducing downtime on production machines. Machinists and CNC operators in job shops, automotive suppliers, and general metal fabrication facilities are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide KCP15A fine-grain tip with HPG insert geometry for aggressive steel and cast iron drilling\u003c\/li\u003e\n\u003cli\u003eAlTiN coating via PVD process for elevated thermal resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e16.1mm cutting diameter (0.6339 inches) with 2-flute helical configuration for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method for secure tip retention under high feed rates\u003c\/li\u003e\n\u003cli\u003eCompatible with inclined-exit and stacked-plate drilling applications\u003c\/li\u003e\n\u003cli\u003eReplaceable-tip design reduces cost per hole versus solid carbide drills in high-volume operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the KTFS-series replaceable-tip drill body platform.

Power down and de-energize the machine spindle before seating or removing the carbide tip. Use the correct torque driver and clamp hardware specified by the KTFS tool body to ensure proper tip retention  -  do not substitute fasteners. Verify runout and tool projection with an indicator before first cut, particularly when drilling inclined or stacked workpieces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 16.1mm (0.6339 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\u003eInsert Geometry\u003c\/strong\u003e: HPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: U\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\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.0mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3170 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.4548 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 12.0mm (0.59 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\u003eSeries\u003c\/strong\u003e: KTFSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KTFSS16100HPGM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 6388534\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743187796274,"sku":"6388534","price":200.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/624843d60c5b631bde244197f2471375.jpg?v=1788843726","url":"https:\/\/voomisupply.com\/products\/kennametal-6388534-carbide-replaceable-tip-drill-16-1mm","provider":"Voomi Supply","version":"1.0","type":"link"}
