The tip carries the ISO designation KSEM2100HPGM and is manufactured from fine-grain solid carbide in grade KCPM45, coated with TiAlN via a PVD process. The 140-degree drill point angle and HPG insert geometry promote stable entry and reduced thrust force. With a cutting diameter of 21 millimeters and helical fluting, this drill is suited to production-volume drilling where repeatability and tip-swap efficiency matter. Coolant-through capability, including MQL (minimum quantity lubrication) compatibility, supports extended tool life in demanding cuts.\u003c\/p\u003e\n\u003cp\u003eThis replaceable tip drill is intended for use in CNC machining centers and turning centers where rigid toolholding and controlled feeds are standard. It is built for drilling into steel and stainless steel workpieces, including inclined-exit and stacked-plate drilling scenarios. The clamp-style insert holding method and 2-flute, 2-margin geometry allow quick tip changes without removing the drill body from the spindle, reducing machine downtime between operations. It is appropriate for job shop and production environments running ISO P and M material groups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21mm cutting diameter with 0.8268 inch decimal equivalent\u003c\/li\u003e\n  \u003cli\u003eFine-grain solid carbide tip in KCPM45 grade for wear resistance in steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating supports elevated cutting temperatures and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree standard point angle with HPG insert geometry for stable entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design with MQL compatibility for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eClamp-type insert holding enables fast tip replacement without disturbing the drill body\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 Plus series drill bodies accepting insert seat size 3.

Verify the insert seat is clean and free of chips before seating the tip, as debris under the tip will cause premature failure or runout. Follow the drill body manufacturer torque guidelines for the clamping screw. Confirm coolant-through channels are clear and delivering adequate flow or MQL before commencing drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 21mm (0.8268 inches)\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: KCPM45\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\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: HPG\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\u003c\/strong\u003e: 0.4134 inches (10mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 3\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 (MQL compatible)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel (ISO P, M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KSEM Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: KSEM2100HPGM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.037 pounds\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: 5397485\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732609138994,"sku":"5397485","price":244.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/700565d6c3fbfe973e5a911dd7970504.jpg?v=1788744952","url":"https:\/\/voomisupply.com\/products\/kennametal-5397485-replaceable-tip-drill-21mm-ksem-plus","provider":"Voomi Supply","version":"1.0","type":"link"}
