The solid carbide tip carries the KC7315 manufacturer grade with a TiAlN coating applied via PVD process, providing thermal resistance and edge wear protection during aggressive drilling operations. The cutting diameter measures 7\/8 inch (0.8752 inch decimal, 22.23 mm), and the drill features a 140-degree point angle with a standard point type. Two helical flutes and a 2-margin geometry support chip evacuation and bore accuracy. The tip is secured by a clamp-style insert holding method and seats in an insert seat size 4 body. Licensed machinists and tool-and-die professionals are the primary installers of this tooling.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip drill is suited for drilling operations in steel workpieces, including inclined exit conditions and stacked plate configurations. The KSEM series design targets production machining environments where tip replacement speed and consistent hole geometry are priorities. The 2-flute, 2-margin, coolant-ready body geometry supports stable cutting in both through-hole and interrupted-exit drilling scenarios. Coolant-through capability is not present on this tip. The functional length is 0.4375 inch (7\/16 inch), making it appropriate for shallow-to-moderate depth drilling applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide tip with KC7315 grade and fine grain material for edge retention in steel\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for thermal and oxidation resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e140-degree included point angle for reduced thrust and accurate self-centering\u003c\/li\u003e\n  \u003cli\u003e2-flute helical geometry with 2-margin design for bore straightness and chip control\u003c\/li\u003e\n  \u003cli\u003eClamp-style tip retention in KSEM insert seat size 4 body for repeatable tip indexing\u003c\/li\u003e\n  \u003cli\u003eRated for inclined exit and stacked plate drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KSEM series insert seat size 4 drill bodies.

Use the correct torque wrench and clamp screw specified by the drill body manufacturer  -  do not substitute fasteners or over-torque the clamp. Inspect the insert seat for chips or debris before seating the new tip to ensure full contact and accurate runout. Verify correct tip orientation and seating before resuming machining operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Inch)\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter (Decimal Inch)\u003c\/strong\u003e: 0.8752 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter (mm)\u003c\/strong\u003e: 22.23 mm\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: KC7315\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\u003eSeries\u003c\/strong\u003e: KSEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003eFunctional Length (Decimal Inch)\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 11.00 mm\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 (ISO Code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KSEM0875HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0734 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 2047429\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742293754162,"sku":"2047429","price":301.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/92be34a60d750a34d936c923ad92f2c7.jpg?v=1788836550","url":"https:\/\/voomisupply.com\/products\/kennametal-2047429-ksem-replaceable-tip-drill-7-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
