The drill features a 23mm (0.9055 inch) cutting diameter with a 140-degree included angle and an MEL insert geometry. The tip is manufactured from solid carbide and coated with TiAlCr and TiSi via a PVD coating process, providing wear resistance and thermal stability during high-feed drilling operations. Through-coolant capability is built in, supporting higher cutting speeds and longer tool life in production settings. This drill is typically installed and changed out by machinists and tooling technicians on CNC machining centers.\u003c\/p\u003e\u003cp\u003eThe 5KHZ251 is suited for machining a range of workpiece materials corresponding to ISO material codes K, M, P, and S, which cover cast irons, stainless steels, carbon and alloy steels, and high-temperature alloys. The replaceable-tip design reduces downtime by allowing tip exchange without removing the drill body from the spindle. This makes it a practical choice for high-volume production shops running automated or semi-automated machining lines where consistent hole quality and fast changeovers are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide replaceable tip for extended tool life and consistent cutting performance\u003c\/li\u003e\n\u003cli\u003eTiAlCr and TiSi PVD coating for thermal and wear resistance\u003c\/li\u003e\n\u003cli\u003e23mm cutting diameter with 140-degree included angle and MEL insert geometry\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design supports chip evacuation and higher cutting speeds\u003c\/li\u003e\n\u003cli\u003eCompatible with ISO material groups K, M, P, and S workpiece materials\u003c\/li\u003e\n\u003cli\u003eSMD series body allows fast tip replacement without spindle removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe 5KHZ251 tip is part of the SUMITOMO SMD series and is designed for use with compatible SMD series drill bodies.

Ensure the spindle is fully stopped and the machine is in a safe state before changing the drill tip. Proper seating of the tip in the body is critical to accuracy and should be verified before resuming cutting. Consult the machine tool manufacturer and SUMITOMO tooling guidelines for recommended clamping torque and runout tolerances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 23mm (0.9055 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 140 degrees\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: ACX80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SMD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Geometry\u003c\/strong\u003e: MEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlCr and TiSi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: K, M, P, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5KHZ251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":52057488458034,"sku":"5KHZ251","price":181.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0e73c6fff832b5019feaf4b10380ecc_60b76d1d-0977-4a07-9daf-6e08b8b1b370.jpg?v=1790038928","url":"https:\/\/voomisupply.com\/products\/sumitomo-5khz251-carbide-replaceable-tip-drill-23mm-acx80","provider":"Voomi Supply","version":"1.0","type":"link"}
