Built from fine-grain solid carbide and coated with AlTiN via a PVD process, this tip delivers reliable performance in demanding drilling applications. It measures 0.75 inches in cutting diameter with a 140-degree point angle and an HPL insert geometry optimized for low cutting forces. The KTFST07500HPL designation identifies the ISO number for this tip. Coolant-through capability is built in, supporting through-spindle coolant delivery for improved chip evacuation and tool life. Seat size X ensures a precise mechanical fit into the compatible KTFST drill body. Installation is performed by machinists and tooling specialists in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis replaceable drill tip is primarily suited for drilling stainless steel and other difficult-to-machine materials classified under ISO material code M. The helical flute design with 2 flutes and 2 margins supports accurate hole entry, inclined surface exits, and stacked-plate drilling operations. The 140-degree included angle reduces thrust force on entry and promotes self-centering on challenging workpiece geometries. Typical applications include precision drilling in aerospace, food processing, and industrial fabrication where stainless steel is the primary workpiece material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFine-grain solid carbide construction for toughness and wear resistance in ISO-M materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating applied via PVD process for high-temperature oxidation resistance\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with HPL geometry reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports through-spindle coolant delivery for chip evacuation\u003c\/li\u003e\n\u003cli\u003e2-flute, 2-margin, helical flute configuration supports inclined exits and stacked-plate drilling\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method with seat size X for secure, repeatable seating in KTFST bodies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KTFST-series modular drill bodies accepting seat size X replaceable tips.

Ensure the drill body is fully removed from the spindle and de-energized before seating or removing the tip. Use the manufacturer-specified torx or clamping key to secure the clamp to the correct seating torque per the KTFST body documentation  -  do not substitute tools or overtighten. Inspect the insert seat for chips, debris, or wear before installing a new tip, as seat damage will affect runout and hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.75 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: HPL\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\u003eManufacturer Grade\u003c\/strong\u003e: KCMS15\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\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\u003eFlute Length\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.5313 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: X\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: Yes\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\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\u003eSeries\u003c\/strong\u003e: KTFST\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KTFST07500HPL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.027 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: 6370939\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739768750386,"sku":"6370939","price":245.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f414b926d81f3542bd0b1e70121cd54_087d7a43-78e1-4792-bc4d-909abba9528a.jpg?v=1788818641","url":"https:\/\/voomisupply.com\/products\/kennametal-6370939-replaceable-drill-tip-0-75in-140deg-kcms15","provider":"Voomi Supply","version":"1.0","type":"link"}
