Built from solid carbide, this tool drills a pilot hole and forms an 82-degree countersink in a single operation, reducing setup time and tool changes. The No. 3 trade size features a 1\/4 inch body diameter, a 7\/64 inch drill point diameter, and a 7\/64 inch drill point length. Overall length is 2 inches. The plain cutting edge and right-hand cutting direction make it compatible with standard drill press and CNC machine spindles. Machinists, tool-and-die technicians, and fabricators use this tool for countersinking fastener seats to flush or below-flush depth.\u003c\/p\u003e\u003cp\u003eThis combo drill countersink is suited for production and job-shop environments where consistent countersink geometry is required. It is commonly used in metalworking applications including sheet metal fabrication, machine assembly, and fixture building where flathead screw or bolt seating is needed. The double end type extends tool life by providing two usable cutting ends. It is well matched to CNC machining centers, manual drill presses, and turret lathes running right-hand spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for hardness and wear resistance in demanding materials\u003c\/li\u003e\n\u003cli\u003eCombination drill and countersink reduces operations to a single tool pass\u003c\/li\u003e\n\u003cli\u003e82-degree included angle matches standard flathead fastener geometry\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends, extending service life\u003c\/li\u003e\n\u003cli\u003ePlain cutting edge style for clean, consistent countersink finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cut compatible with standard spindle rotation on most machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard No. 3 combination drill and countersink for use in drill presses, CNC machining centers, and manual lathes with right-hand spindle rotation accepting a 1\/4 inch body diameter tool.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this tooling should be performed by a qualified machinist or tooling technician. Secure the tool firmly in the appropriate collet or drill chuck before operation and verify spindle speed is appropriate for the workpiece material and tool diameter. Always power down and lock out the machine before changing or inspecting tooling. Do not exceed the tool's rated cutting parameters for the material being machined.\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\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241603\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: 300-002005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741860397362,"sku":"300-002005","price":58.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e86b51ec765906003c7b15aa6493f13f.jpg?v=1788833886","url":"https:\/\/voomisupply.com\/products\/hertel-300-002005-combo-drill-countersink-1-4-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
