With a 1\/2 inch diameter tip, an overall length of 1-27\/32 inches, and an 80 degree included angle, this tool delivers clean, consistent countersink profiles in a compact form factor. The straight shank allows direct chuck mounting in standard drill presses and hand drills. Machinists, pipefitters, and general tradespeople reach for single flute countersinks when they need a smooth finish without chatter on ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for light-to-medium duty shop and field use where a precise 80 degree chamfer is required. Typical applications include countersinking screw heads flush to a surface, chamfering drilled hole edges to remove burrs, and preparing holes for fastener seating on panel assemblies, pipe flanges, and structural components. Its compact overall length makes it practical in tighter work envelopes where a longer tool would be awkward.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle flute design reduces chatter and delivers a smooth countersink finish\u003c\/li\u003e\n  \u003cli\u003e80 degree included angle suits common fastener countersink profiles\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch diameter tip for medium hole chamfering work\u003c\/li\u003e\n  \u003cli\u003eStraight shank compatible with standard drill press and hand drill chucks\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1-27\/32 inches for use in tighter workspaces\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.05 pounds for easy handling and reduced fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use countersink tool compatible with any standard drill press or hand drill accepting a straight shank bit in the appropriate chuck size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall the straight shank securely into a properly sized drill chuck before use. Ensure the workpiece is clamped or fixtured to prevent movement during operation. Use appropriate cutting speeds for the material being chamfered and apply cutting fluid on harder metals to extend tool life. Always wear appropriate eye protection when operating rotary cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-27\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Configuration\u003c\/strong\u003e: Single flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 698464074639\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: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4710799\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51346465882418,"sku":"4710799","price":30.86,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310538596.jpg?v=1782081005","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-4710799-countersink-1-2-in-80-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
