It measures 0.6875 inches in cutting diameter and features a 140-degree point angle with a helical, 2-flute geometry. The tip is manufactured from fine-grain solid carbide and carries a PVD-applied AlTiN coating that improves heat resistance and tool life at the cutting edge. The HPL insert geometry and KCMS15 grade are matched specifically for demanding metal-removal cycles where edge stability and coating adhesion matter. Coolant-through capability is built in, supporting direct delivery to the cutting zone. This tip is installed by machinists and CNC tooling professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis replaceable drill tip fits KTFST-series holders with insert seat size V and ISO designation KTFST06875HPL. It is suited for drilling operations in stainless steel (ISO material code M), including inclined-exit drilling and stacked-plate drilling. The 2-flute, 2-margin configuration with through-coolant support makes it appropriate for CNC machining centers running coolant-fed spindles. Typical applications include precision hole-making in aerospace, medical, and industrial fabrication where stainless steel is the primary workpiece material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFine-grain solid carbide construction for edge toughness in stainless and hard alloys\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating applied via PVD process for thermal resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with HPL insert geometry reduces cutting forces on entry and exit\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers fluid directly to the cutting zone for chip evacuation and heat control\u003c\/li\u003e\n  \u003cli\u003eHelical flute, regular spiral, 2-flute\/2-margin configuration supports consistent chip flow\u003c\/li\u003e\n  \u003cli\u003eClamp-held insert seating in KTFST seat size V for repeatable positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KTFST-series replaceable-tip drill holders requiring insert seat size V.

Before seating or removing the tip, de-energize and lock out the machine spindle per facility lockout\/tagout procedures. Use the appropriate torque wrench and clamp screw specified by the holder manufacturer  -  do not over-torque the clamp, as carbide tips are brittle and can crack under uneven clamping load. Verify coolant-through passages are clear and aligned before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.6875 inches (11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003eSeries\u003c\/strong\u003e: KTFST\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: V\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\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\u003eFunctional Length\u003c\/strong\u003e: 0.3438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\/Projection\u003c\/strong\u003e: 0.4871 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 12.00 mm\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\u003eISO Number\u003c\/strong\u003e: KTFST06875HPL\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: 0.26 pounds\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: 6370922\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744391037234,"sku":"6370922","price":221.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f414b926d81f3542bd0b1e70121cd54_4ca4be26-ecde-4c1e-9eff-a5a2fe2d24e4.jpg?v=1788856115","url":"https:\/\/voomisupply.com\/products\/kennametal-6370922-replaceable-drill-tip-0-6875-in-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
