Sized at trade size 8 with a 3\/4 inch body diameter, it drills and countersinks in a single operation, reducing setup time on the machine or drill press. The 5\/16 inch drill point is ground to a 118-degree point angle, and the 60-degree included angle on the countersink portion is standard for most fastener seat preparation. Overall length is 6 inches, qualifying this as a long-length tool. The double-end design extends service life by providing two usable cutting ends before the tool is retired.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is suited for metalworking, fabrication, and machining operations where countersunk fastener holes are required. The right-hand cutting direction makes it compatible with conventional drill presses, CNC machining centers, and handheld power drills running standard rotation. The plain cutting edge style handles general-purpose countersinking in ferrous and non-ferrous stock. Machinists, tool and die makers, and metal fabricators working in production or job-shop environments will find this tool fits standard toolholding setups without modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCombination drill and countersink in one tool  -  drills pilot hole and seats countersink in a single pass\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends for extended tool life\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle suits standard metalworking applications\u003c\/li\u003e\n\u003cli\u003e60-degree included countersink angle matches common flat-head fastener requirements\u003c\/li\u003e\n\u003cli\u003eLong-length at 6 inches overall for reach in deeper setups\u003c\/li\u003e\n\u003cli\u003eBright, uncoated high-speed steel finish for general-purpose use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose combination drill countersink for use in standard drill chucks and collet-style toolholders accepting a 3\/4 inch shank in metalworking and fabrication applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling technician familiar with rotating cutting tools. Secure the tool firmly in the chuck or collet and verify runout before beginning a cut. Always operate at the recommended surface footage for high-speed steel tooling against the workpiece material, and apply cutting fluid where appropriate to manage heat. Power down and de-energize the machine before changing or inspecting the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 5\/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: 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: Plain\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong Length Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.58 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: KEO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 907-000-179\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KEO","offers":[{"title":"Default Title","offer_id":52086203187506,"sku":"907-000-179","price":97.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f94a3ba4b6e0da102d27fc00088a2ac2.jpg?v=1790059540","url":"https:\/\/voomisupply.com\/products\/keo-907-000-179-combo-drill-countersink-size-8-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
