Built from high speed steel with a bright polished finish, it runs a 3\/64 inch point diameter on a 1\/8 inch body diameter. The 60-degree included angle and radius cutting edge style make it suited for deburring and seating flat-head fasteners in metal fabrication, sheet metal, and general machining work. The double-end configuration extends usable tool life. Overall length is approximately 31.30 millimeters. This tool is installed and used by machinists, tool-and-die workers, and sheet metal fabricators.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink fits applications where a clean pilot hole and countersink must be produced in one pass. Common uses include preparing holes for flat-head machine screws in aluminum, mild steel, and similar metals. The Series 594 designation places it within GUHRING's standard combination drill countersink line. Right-hand cutting direction is standard for conventional spindle rotation. At 0.009 pounds, the tool is lightweight and compatible with drill presses, CNC machining centers, and hand-held drill motors with appropriate collet or chuck tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombination drill and countersink in one tool — eliminates a separate tool change\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for general-purpose cutting in ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces chip adhesion and friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle seats standard flat-head fasteners accurately\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two usable cutting ends, extending tool service life\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut for use with standard clockwise spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard combination drill countersink for use in drill presses, CNC machining centers, and hand-held drill motors equipped with a compatible collet or drill chuck accepting a 1\/8 inch body diameter shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA machinist or fabricator should secure the tool in a properly sized collet or drill chuck before operation. Verify spindle rotation is set to right-hand before engaging the workpiece. Always clamp the workpiece securely to prevent movement during the combined drilling and countersinking operation. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Diameter\u003c\/strong\u003e: 3\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 31.30 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright Polished\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 594\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005940011900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728548495666,"sku":"9005940011900","price":31.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313d72d88354e8e3db7561e5f8bae62d.jpg?v=1788693139","url":"https:\/\/voomisupply.com\/products\/guhring-9005940011900-combo-drill-countersink-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
