It carries an 18.50 mm cutting diameter, a 180-degree flat point angle, and a straight flute configuration with two flutes and four margins. The tip is manufactured from fine-grain solid carbide in grade KCP15A and is PVD-coated with AlTiN for thermal resistance and wear performance during demanding metal-cutting operations. Seat size is W, and the insert geometry is FEG. Licensed machinists, CNC operators, and toolroom technicians working with modular drill bodies will find this tip suited for high-productivity hole-making applications.\u003c\/p\u003e\u003cp\u003eThis replaceable tip is intended for use in KTFSS-series modular drill bodies sized for the W seat. Supported applications include flat-bottom drilling, inclined entry and inclined exit drilling, and counter-boring operations. Primary workpiece materials are steel, stainless steel, and cast iron, corresponding to ISO material codes P, M, and K. The straight spiral and flat point geometry make it well suited for through-feature and shallow flat-bottom holes where a conventional point angle would leave an unacceptable cone-shaped floor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18.50 mm cutting diameter with 0.7283 inch decimal equivalent\u003c\/li\u003e\n\u003cli\u003e180-degree flat point angle for flat-bottom and inclined-surface drilling\u003c\/li\u003e\n\u003cli\u003eFine-grain solid carbide substrate in manufacturer grade KCP15A\u003c\/li\u003e\n\u003cli\u003eAlTiN coating applied via PVD process for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTwo-flute, four-margin geometry supports stability in steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003eStraight flute design with clamp-type insert holding; no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KTFSS-series modular drill bodies requiring an W-seat replaceable tip.

Use the manufacturer-specified clamping torque driver and seating method for the KTFSS body to avoid seat damage. Inspect the seat and clamping surfaces for chips or debris before seating the tip. Do not exceed the recommended cutting parameters for the KCP15A grade in the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 18.50 mm (0.7283 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\u003eSpiral Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.3642 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length \/ Projection\u003c\/strong\u003e: 0.4166 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 11.00 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: W\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\u003eSeries\u003c\/strong\u003e: KTFSS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KTFSS18500FEGM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel; Stainless Steel; Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P; M; K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.73 inches x 2.73 inches x 2.64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.046 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: 6771156\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733224227122,"sku":"6771156","price":234.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8c8486841931b0a38a21fa8f3f3f4662_77555b0e-8fd6-4b65-9068-d85458e694ba.jpg?v=1788752984","url":"https:\/\/voomisupply.com\/products\/kennametal-6771156-replaceable-drill-tip-18-50mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
