The tip carries an AlTiN coating applied via PVD process, which improves heat resistance and extends tool life in demanding cutting environments. It features a 180-degree drill point angle, two helical flutes, and a two-margin geometry for stable entry and exit. The manufacturer grade is KCP15A with a fine-grain carbide substrate, and the HPG insert geometry is engineered for consistent chip control. The drill body uses a clamp-style insert holding method with an insert seat size of V, and the tool is part of the KTFSS series.\u003c\/p\u003e\u003cp\u003eThis replaceable tip drill is suited for general drilling operations in steel and cast iron in both production and job-shop environments. It is specifically rated for inclined exit drilling and stacked-plate drilling applications, making it appropriate for structural fabrication, machined-component production, and similar metalworking contexts. The two-flute, two-margin, no-coolant-through configuration is noted in the application data. It is intended for use by machinists and CNC operators working with ferrous workpiece materials designated under ISO material codes P and K.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating via PVD process for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eKCP15A fine-grain solid carbide grade for toughness in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eHPG insert geometry with two helical flutes and two margins for stable chip control\u003c\/li\u003e\n\u003cli\u003eRated for inclined exit and stacked-plate drilling applications\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding with V-seat for secure tip retention\u003c\/li\u003e\n\u003cli\u003e180-degree drill point angle for standard entry geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replaceable tip for KTFSS series drill bodies accepting the V insert seat size.

Use the appropriate clamp key or torque tool specified for the KTFSS body series when seating the tip. Inspect the insert seat for chips or contamination before installing a new tip. Follow the toolholder manufacturer guidelines for proper clamping torque and runout verification 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: 0.6875 inches (11\/16 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\u003eDrill Point Angle\u003c\/strong\u003e: 180 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\u003eInsert Geometry\u003c\/strong\u003e: HPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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: 0.4910 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: Steel, Cast Iron (ISO P, K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: KTFSS06875HPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.028 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 6388564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743422972210,"sku":"6388564","price":177.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6347f7cd35a09a3bd394746d06feef03_23b48e09-1bdf-4509-98a0-58c0eb9034d4.jpg?v=1788846876","url":"https:\/\/voomisupply.com\/products\/kennametal-6388564-replaceable-tip-drill-11-16-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
