Part of the SMD series, this tip features a 0.8268-inch (21.00 mm) cutting diameter and is manufactured from solid carbide with a PVD-applied TiAlCr and TiSi dual-layer coating. The MEL insert geometry and 140-degree included angle are designed to deliver consistent entry and exit performance across a wide range of workpiece materials. Coolant-through design channels cutting fluid directly to the cutting edge, helping manage heat and chip evacuation at depth. This tip is typically installed by machinists and CNC operators in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 5KHZ238 carries a universal primary workpiece material classification, covering cast iron (K), stainless and heat-resistant alloys (M), steel (P), and superalloys (S). This broad compatibility makes it a practical stock item for shops running varied materials without dedicated tooling for each. It is well suited to through-coolant spindle setups where consistent chip removal is critical for hole quality and tool life in moderate to high-volume drilling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and edge retention in demanding materials\u003c\/li\u003e\n  \u003cli\u003ePVD-applied TiAlCr and TiSi dual-layer coating for thermal resistance and wear protection\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design for active chip evacuation and heat control at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e140-degree included angle (MEL geometry) for stable entry and clean hole geometry\u003c\/li\u003e\n  \u003cli\u003eUniversal workpiece material rating covering K, M, P, and S material groups\u003c\/li\u003e\n  \u003cli\u003eSMD series replaceable tip format allows body reuse and simplified edge replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Sumitomo SMD series modular drill bodies that accept MEL-geometry replaceable tips at 21.00 mm cutting diameter.

Power down the machine and confirm zero-energy state before tip removal or installation. Inspect the tip seat in the drill body for wear, chips, or contamination before seating a new tip, as a damaged seat will affect runout and hole quality. Through-coolant connections should be verified for alignment and flow before returning the assembly to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.8268 inches (21.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\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\u003eIncluded Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (K, M, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5KHZ238\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51746189017394,"sku":"5KHZ238","price":168.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0e73c6fff832b5019feaf4b10380ecc_a1a20e90-228e-414b-88cb-7059987a28ce.jpg?v=1788866909","url":"https:\/\/voomisupply.com\/products\/sumitomo-5khz238-replaceable-drill-tip-acx80-0-8268-in","provider":"Voomi Supply","version":"1.0","type":"link"}
