It drills a pilot hole and forms a countersink angle simultaneously, reducing setup time and tool changes at the spindle. Trade size 1 with a bright (polished) finish, this tool is used in metal fabrication, machine shops, and general holemaking applications. It weighs 0.14 pounds and ships as a single unit. Machinists, tool and die workers, and maintenance techs working on drill presses or lathes are the primary users of this type of tooling.\u003c\/p\u003e\n\u003cp\u003eCombination drill and countersinks at trade size 1 are suited for light-duty center drilling on lathes and milling machines, as well as countersinking for flat-head fasteners in metalworking and fabrication environments. This tool category falls under holemaking and is classified specifically as a combination drill and countersink. The bright polished finish reduces friction during cutting and allows for visual inspection of the cutting edges. Sold individually, it fits standard toolholders and chucks compatible with size 1 center drills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCombination drill and countersink in a single tool  -  pilot hole and countersink angle in one pass\u003c\/li\u003e\n  \u003cli\u003eTrade size 1 for light-duty center drilling and countersinking applications\u003c\/li\u003e\n  \u003cli\u003eBright (polished) finish reduces friction and allows easy edge inspection\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.14 pounds  -  suitable for high-speed spindle use\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit with no minimum order quantity beyond one piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for size 1 combination drill and countersink applications in standard drill press, lathe, or milling machine chucks and toolholders that accept this trade size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of combination drill and countersinks is performed by machinists or skilled fabricators using a lathe, drill press, or milling machine. Secure the tool firmly in the chuck or toolholder before operation and verify runout before beginning the cut. Always power down the machine and follow lockout\/tagout procedures before changing tooling. Do not exceed the recommended RPM range for the material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrade Size\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright (Polished)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Combination Drill and Countersink\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: 23301\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":68388318019890,"sku":"23301","price":116.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_c3509917-c5d1-4099-ad0e-7464cb6e420e.jpg?v=1793904515","url":"https:\/\/voomisupply.com\/products\/value-collection-23301-combo-drill-countersink-size-1","provider":"Voomi Supply","version":"1.0","type":"link"}
