The solid carbide tip carries a KC7315 grade designation with a PVD-applied TiAlN coating and an HPG insert geometry for improved chip control and edge stability. The 140-degree drill point angle suits standard entry and exit conditions. With a 25.5mm cutting diameter and through-coolant capability, this drill is suited for CNC machining centers where consistent hole quality and tool life are required. Installation and tip replacement are performed by machining professionals in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis replaceable tip drill is designed for drilling operations in steel (ISO P) and cast iron (ISO K) workpieces. Supported applications include standard drilling, inclined-surface entry and exit, stacked-plate drilling, and through-coolant or MQL (minimum quantity lubricant) setups. The KSEM insert seat size 5 platform uses a clamp-style holding method, allowing tip replacement at the machine without removing the drill body. Its two-flute, two-margin helical flute design promotes straight tracking and clean hole walls in these material categories.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide tip with KC7315 fine-grain grade for wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN coating for thermal and oxidation resistance at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e140-degree standard drill point angle for controlled entry on flat and mildly inclined surfaces\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design compatible with MQL and direct coolant delivery\u003c\/li\u003e\n\u003cli\u003eKSEM seat size 5 clamp-style interface for fast, repeatable tip indexing\u003c\/li\u003e\n\u003cli\u003eRated for inclined exit, stacked-plate, and standard through-hole drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KSEM-series drill bodies accepting seat size 5 replaceable tips.

Always power down and lock out the machine spindle before seating or removing the replaceable tip. Use the manufacturer-specified torque tool and clamp procedure for the KSEM seat interface to ensure proper tip retention and runout. Verify coolant passage alignment and flow before returning the tool to cutting service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 25.50mm (1.0039 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KSEM2550HPGM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC7315\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\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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: HPG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 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\u003eFlute Length\u003c\/strong\u003e: 13.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.5015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 13.00mm\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P, K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0595 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: 2499791\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744576635186,"sku":"2499791","price":268.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01ae107a4518d28100d8563cf4a0b401_8fa5c19f-f5cd-4817-a1c2-0b0831ffceb5.jpg?v=1788858484","url":"https:\/\/voomisupply.com\/products\/kennametal-2499791-carbide-replaceable-tip-drill-25-5mm","provider":"Voomi Supply","version":"1.0","type":"link"}
