Built from solid carbide with a TiN (titanium nitride) coating, it delivers extended tool life in demanding production and repair environments. The body diameter is 1\/4 inch, the drill point diameter is 7\/64 inch, and the overall length is 2 inches. The 118-degree drill point angle and 60-degree included countersink angle are standard geometry for metalworking applications. This tool is used by machinists, tool-and-die tradespeople, and maintenance technicians working in metal fabrication and aerospace-adjacent repair environments.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is suited for use in ferrous and non-ferrous metals where a precisely positioned countersink seat is required before fastener installation. It is a Trade Size No. 3 tool with a plain cutting edge style and a double end type, allowing both ends to be used before the tool is retired. Right-hand cutting direction makes it compatible with standard drill press and CNC spindle rotation. It is not an aircraft-style or long-length variant, and the cutter head is not insertable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle provides standard center-drilling geometry\u003c\/li\u003e\n\u003cli\u003e60-degree included countersink angle matches common flat-head fastener seat requirements\u003c\/li\u003e\n\u003cli\u003eDouble-end design doubles usable tool life before replacement\u003c\/li\u003e\n\u003cli\u003eRight-hand cut compatible with standard spindle rotation on drill presses and CNC machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for Trade Size No. 3 combination drill countersinks used in standard drill press, manual lathe, and CNC machining center applications requiring a 1\/4 inch body diameter and 7\/64 inch drill point.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this tool is performed by machinists or maintenance technicians operating drill presses, lathes, or CNC equipment. Ensure the machine spindle is fully stopped and de-energized before loading or changing the tool. Secure the tool firmly in an appropriate collet or drill chuck rated for the 1\/4 inch shank diameter. Use appropriate cutting fluid or coolant for the workpiece material to preserve tool life and surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: No. 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Diameter\u003c\/strong\u003e: 7\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 7\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eWeight\u003c\/strong\u003e: 0.1 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: 300-001505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729930617138,"sku":"300-001505","price":55.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef5d6366114a29b9e6103a8473264636.jpg?v=1788709906","url":"https:\/\/voomisupply.com\/products\/hertel-300-001505-combo-drill-countersink-1-4-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
