Built from fine-grain solid carbide in grade KCP15A, this tip features a PVD-applied AlTiN coating that supports high-temperature cutting and resists wear against abrasive workpiece materials. The flat 180-degree point geometry produces a true flat-bottom hole, making it well suited for applications where point angle breakout and hole-bottom condition are critical. With a 16.50 mm cutting diameter and straight flute configuration, the tip is held in place by a clamp-style seat mechanism. Machinists and toolroom technicians install and index these tips at the machine without special equipment.\u003c\/p\u003e\u003cp\u003eThis tip is intended for drilling operations in steel, stainless steel, and cast iron — corresponding to ISO material groups P, M, and K. Application coverage extends beyond straight drilling to include inclined entry, inclined exit, flat-bottom drilling, and counterboring. The straight spiral type and 2-flute, 4-margin geometry support stable cutting action across these varied entry and exit conditions. It is sized for an insert seat size U in KTFSS-series holders and carries the ISO designation KTFSS16500FEGM.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFine-grain solid carbide substrate in manufacturer grade KCP15A for toughness and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003ePVD AlTiN coating extends tool life in steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e180-degree flat point geometry enables flat-bottom hole drilling, counterboring, inclined entry, and inclined exit\u003c\/li\u003e\n\u003cli\u003e2-flute, 4-margin straight flute design for stable, accurate hole geometry\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method allows fast tip indexing at the machine\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement — compatible with external coolant or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KTFSS-series indexable drill bodies that accept insert seat size U.

Power down the spindle and confirm the tool is fully stopped before accessing the tip seat. Use the correct Kennametal torque key or clamp wrench specified for the KTFSS holder to secure the tip — do not substitute unrated tools. Inspect the seating surface and clamp for chips or damage each time the tip is indexed to ensure accurate tip location and prevent premature failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 16.50 mm (0.6496 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 180 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Flat\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: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3248 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.3724 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 9.00 mm\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: KCP15A\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: FEG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KTFSS\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, Stainless Steel, Cast Iron (ISO P, M, K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Drilling, Flat-Bottom Drilling, Inclined Entry, Inclined Exit, Counterboring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.032 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: 6771139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730384748850,"sku":"6771139","price":211.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c8486841931b0a38a21fa8f3f3f4662_2876101b-6f98-4db5-99ad-f742624c0cc9.jpg?v=1788716505","url":"https:\/\/voomisupply.com\/products\/kennametal-6771139-replaceable-drill-tip-16-50mm-kcp15a","provider":"Voomi Supply","version":"1.0","type":"link"}
