Trade size 5 with a 7\/16 inch body diameter, the tool features a 3\/16 inch point diameter and a 90-degree included angle that produces a clean, consistent countersink seat. The bright polished finish reduces friction and aids chip evacuation. At 6 inches overall length, this is a long-length tool suited for reaching deeper workpieces or awkward setups. Right-hand cutting direction is standard for conventional drill press and CNC spindle applications.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is intended for metalworking, fabrication, and maintenance applications where a countersunk fastener seat must be produced efficiently. The double-end configuration extends tool life by providing a second usable end when one side reaches wear limits. Plain cutting edge style makes it straightforward to resharpen in a shop environment. Solid carbide construction supports use in harder materials and at higher surface speeds compared to high-speed steel equivalents. Licensed machinists, toolmakers, and industrial maintenance technicians are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombo drill and countersink in one tool — single-pass operation reduces setup time\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e90-degree included angle for standard countersunk fastener seating\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle for positive center engagement\u003c\/li\u003e\n\u003cli\u003eLong-length at 6 inches overall for extended reach applications\u003c\/li\u003e\n\u003cli\u003eBright polished finish promotes chip flow and reduces built-up edge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard trade size 5 combo drill countersink compatible with drill presses, milling machines, and CNC machining centers using conventional right-hand spindle rotation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed in a drill chuck or collet by a machinist or toolroom technician. Secure the shank fully in the holder and verify runout before machining. Use appropriate cutting fluid or coolant for the workpiece material to preserve carbide edge life. Do not run solid carbide tooling in machines with excessive spindle vibration or play, as carbide is brittle and susceptible to chipping under interrupted or unstable cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright (Polished)\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: Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Countersinking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 300-007005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738939228466,"sku":"300-007005","price":192.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/569c85295e6ffc678fb9de7314e18d80.jpg?v=1788807046","url":"https:\/\/voomisupply.com\/products\/hertel-300-007005-combo-drill-countersink-size-5-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
