Built from high-speed steel (HSS) with a bright uncoated finish, this tool handles ferrous and non-ferrous materials with consistent results. It carries a trade size of 8, a body diameter of 0.75 inches, and an overall length of 3.5 inches. The 82-degree included angle and 118-degree drill point angle are standard for flat-head fastener seating. Machinists and fabricators reach for this tool when accuracy and efficiency on countersink operations matter.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is suited for use in machine shops, fabrication environments, and production drilling applications. It is designed for use in drill presses, CNC machining centers, and manual lathes where a clean countersink seat is required before flat-head screw installation. The double-end design and plain cutting edge style make it appropriate for general-purpose countersinking work across a wide range of materials common in trade and industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suited for general-purpose machining operations\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle optimized for standard flat-head fastener countersinking\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for clean, accurate pilot hole entry\u003c\/li\u003e\n  \u003cli\u003eDouble-end design extends usable tool life\u003c\/li\u003e\n  \u003cli\u003e3.5-inch overall length provides clearance in most standard toolholders\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, manual lathes, and CNC machining centers requiring size 8 countersink geometry with a 0.75-inch body diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tool operators familiar with proper speeds and feeds for HSS tooling. Secure the tool firmly in a compatible chuck or toolholder before operation and verify runout before beginning a cut. Always power down and de-energize the machine before changing or inspecting tooling. Follow applicable shop safety standards and machine manufacturer guidelines during use.\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\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\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 \/ Uncoated\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\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241603\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H-81154080000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736319263026,"sku":"H-81154080000","price":80.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64b1781855f6d5b9a36c0b3a1ed3b8df.jpg?v=1788777200","url":"https:\/\/voomisupply.com\/products\/hertel-h-81154080000-combo-drill-countersink-size-8","provider":"Voomi Supply","version":"1.0","type":"link"}
