This tip features a 0.8071-inch (20.50 mm) cutting diameter and is manufactured from solid carbide with a PVD-applied TiAlCr and TiSi dual coating, designated Grade ACX80. The MEL insert geometry and 140-degree included angle suit a wide range of drilling operations. Coolant-through capability allows cutting fluid to be delivered directly to the cutting edge, supporting chip evacuation and extended tool life in demanding cuts. Licensed machinists and CNC operators install and replace this tip at the machine.\u003c\/p\u003e\n\u003cp\u003eThe 5KHZ237 is rated for universal workpiece material compatibility, covering ISO material groups K (cast iron), M (stainless steel), P (steel), and S (superalloys and titanium). This broad classification makes it a versatile tip for job shops and production environments running mixed-material programs. The replaceable tip format reduces tooling cost compared to solid indexable drills by allowing tip replacement without changing the drill body. It is suited for vertical machining centers, horizontal machining centers, and CNC lathes equipped with compatible SMD-series bodies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.8071-inch (20.50 mm) cutting diameter in the SMD replaceable tip series\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction with PVD-applied TiAlCr and TiSi coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers fluid directly to the cutting zone for chip evacuation\u003c\/li\u003e\n  \u003cli\u003e140-degree included angle with MEL insert geometry for controlled entry and exit\u003c\/li\u003e\n  \u003cli\u003eUniversal material compatibility covering ISO groups K, M, P, and S\u003c\/li\u003e\n  \u003cli\u003eGrade ACX80 designation supports high-productivity drilling in mixed-material production\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 replaceable tips at the 20.50 mm diameter specification.

Disengage spindle power and confirm the machine is in a locked-out, zero-energy state before removing or seating the tip. Use only the manufacturer-recommended torque tool or wrench for the tip retention mechanism — do not over-tighten by feel. Inspect the mating seating surfaces on the drill body for chips or contamination before installing the new tip to ensure proper seating and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.8071 inches (20.50 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\u003eIncluded Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (ISO K, M, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 5KHZ237\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51746465939762,"sku":"5KHZ237","price":164.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0e73c6fff832b5019feaf4b10380ecc_a283cb2c-70e3-45c6-a282-562d19e541e0.jpg?v=1788870549","url":"https:\/\/voomisupply.com\/products\/sumitomo-5khz237-replaceable-drill-tip-0-8071-in-acx80","provider":"Voomi Supply","version":"1.0","type":"link"}
