Built from high speed steel with a bright polished finish, this tool handles trade size 8 work with a 3\/4 inch body diameter and a 5\/16 inch drill point diameter. The 118-degree drill point angle and 90-degree included countersink angle are standard for general-purpose metalworking and woodworking applications. At 6 inches overall length, it is classified as a long-length tool, offering added reach in deeper setups. Machinists and fabricators working with CNC machines, drill presses, or manual setups will find this a reliable single-pass tool.\u003c\/p\u003e\n\u003cp\u003eThis combo drill countersink is suited for production and job-shop environments where countersinking screws flush or below a surface is required in one step. The plain cutting edge style and double end type make it a straightforward choice for ferrous and non-ferrous materials. Typical applications include preparing holes for flat-head fasteners in metal fabrication, sheet metal work, and general machining. It is not an aircraft-style tool and is not tapered, making it appropriate for standard commercial and industrial countersinking tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombines drilling and countersinking in a single pass for faster cycle times\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright polished finish reduces friction and aids chip evacuation\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle suited for general-purpose drilling applications\u003c\/li\u003e\n  \u003cli\u003e90-degree included angle for standard flat-head fastener countersinks\u003c\/li\u003e\n  \u003cli\u003eLong-length design at 6 inches OAL provides added reach in deeper setups\u003c\/li\u003e\n  \u003cli\u003eDouble end type extends tool life by offering two usable ends\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 standard trade size 8 countersinking applications on drill presses, CNC machining centers, and manual drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with proper speeds, feeds, and workholding practices. Secure the workpiece firmly before operation and ensure the tool is properly chucked and centered before engaging the spindle. Follow applicable shop safety standards and machine guarding requirements when operating drilling or milling equipment. Do not exceed the recommended RPM for the tool diameter and material being machined.\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\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: 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\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\u003eLong Length Tool\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H-81155L08060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51745481720114,"sku":"H-81155L08060","price":171.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b48898e5aa764b5a8dd491f90bba3de8.jpg?v=1788864208","url":"https:\/\/voomisupply.com\/products\/hertel-h-81155l08060-combo-drill-countersink-size-8-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
