The solid carbide tip features a fine grain substrate with a PVD-applied AlTiN coating and an HPL insert geometry. At 14mm cutting diameter, it operates with a 140-degree drill point angle, two helical flutes with a regular spiral, and a through-coolant design that delivers cutting fluid directly to the cutting edge. This replaceable tip format is designed for installation into a compatible KTFS series shank body, making tip changes fast without removing the holder from the machine. Primary applications target stainless steel and other M-group workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for drilling operations in stainless steel and similarly difficult-to-machine M-group alloys in both production machining and job shop environments. The HPL geometry and AlTiN finish work together to manage heat and tool wear in these demanding materials. Supported application scenarios include standard drilling, inclined exit drilling, and stacked plate drilling, making it a practical choice for aerospace, medical, and general precision machining setups where a single tip geometry needs to handle variable conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide fine grain substrate in KCMS15 grade for stainless steel and M-group materials\u003c\/li\u003e\n\u003cli\u003ePVD AlTiN coating applied via physical vapor deposition for thermal resistance and wear reduction\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle with HPL insert geometry for controlled chip formation\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design channels fluid to the cutting zone for heat removal and chip evacuation\u003c\/li\u003e\n\u003cli\u003eTwo helical flutes with regular spiral and 2-margin configuration for stability in deep holes\u003c\/li\u003e\n\u003cli\u003eReplaceable tip design mounted via clamp in an R-seat KTFS series holder body\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replaceable tip insert for KTFS series drill bodies accepting an R insert seat size.

Power down and lock out the spindle before seating or removing the tip. Use the correct torque wrench and clamp screw driver per the holder body manufacturer instructions  -  do not over-torque the clamp. Verify seating and runout before initiating a cut, especially when working with stainless steel where a misaligned tip can cause rapid edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 14mm (0.5512 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KTFST14000HPLM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KTFS\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\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: HPL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: R\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.2756 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.3917 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 10mm (0.59 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (M-group)\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: 0.02094 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 6371080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739607335218,"sku":"6371080","price":177.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5316861e4fa58b630d05fcee417e25f4_f363b1ca-0a8f-497c-a92e-5dd8a2ffc27c.jpg?v=1788816859","url":"https:\/\/voomisupply.com\/products\/kennametal-6371080-carbide-replaceable-tip-drill-14mm","provider":"Voomi Supply","version":"1.0","type":"link"}
