Machined from cobalt high-speed steel with a bright uncoated finish, this tool handles harder workpiece materials where standard high-speed steel loses edge retention. The 90-degree included angle produces a standard countersink profile. The double-end design extends tool life by providing two usable cutting ends before replacement. With a plain cutting edge style and right-hand cut direction, it suits conventional drill press and hand-drill setups used by machinists, pipefitters, and HVAC fabricators working with ferrous and stainless materials.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is intended for countersinking and spot-drilling applications in metalworking, fabrication, and mechanical assembly work. The 3\/4 inch body diameter provides mass for rigidity during the countersinking pass, reducing chatter. The 5\/16 inch drill point diameter and 5\/16 inch point length suit size 8 fastener clearance and seating requirements. It is not an aircraft-style tool and is not classified as a long-length tool, making it a straightforward bench or floor-drill application for trade and production shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt high-speed steel construction for improved heat and wear resistance versus standard HSS\u003c\/li\u003e\n  \u003cli\u003eDouble-end design provides two cutting ends, extending service life before replacement\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle matches standard countersink fastener head geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with plain cutting edge style for use in conventional drill setups\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish with no coating buildup to interfere with dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch body diameter provides rigidity to reduce chatter during countersinking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use combo drill countersink for size 8 fastener applications in standard drill press, CNC, or hand-drill setups requiring a 90-degree countersink profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this tool should be performed by a qualified machinist or tradesperson familiar with cutting tool safety. Always power down and de-energize the drill press or machine spindle before mounting or changing tooling. Secure the workpiece properly to prevent movement during drilling and countersinking operations. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection when working with cobalt tooling on ferrous or stainless materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.5 inches\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: Cobalt 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\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\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BC11P0008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696249176370,"sku":"BC11P0008","price":44.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c38e88cd0acfa3def56c618c34f635dc.jpg?v=1788340666","url":"https:\/\/voomisupply.com\/products\/value-collection-bc11p0008-combo-drill-countersink-size-8","provider":"Voomi Supply","version":"1.0","type":"link"}
