With a 1\/2-inch head diameter and an 82-degree included angle, it produces flush-mount recesses for flat-head fasteners conforming to standard 82-degree seating geometry. The 6-flute configuration distributes cutting load evenly, reducing chatter and producing a smoother finish compared to fewer-flute designs. The body is manufactured from high speed steel (HSS), which maintains cutting edge integrity across a wide range of workpiece materials. The 1\/4-inch shank fits standard drill chucks and quick-change collet systems commonly used in machine shops and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for general metalworking, light fabrication, and maintenance applications where 82-degree flat-head screw seats are required. It performs in drill presses, CNC machining centers, and hand-held power drills with a compatible 1\/4-inch chuck or collet. Typical applications include deburring drilled holes, preparing fastener seats in sheet metal panels, and countersinking pilot holes in structural components. Machinists, maintenance technicians, and tool and die workers are the primary installers and users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-inch head diameter produces standard flush-mount countersink seats\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches flat-head fastener seating geometry\u003c\/li\u003e\n  \u003cli\u003e6-flute design minimizes chatter and improves surface finish quality\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across metal and plastic workpieces\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank diameter fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in any drill press, machining center, or hand-held power drill accepting a 1\/4-inch shank.

Secure the 1\/4-inch shank firmly in the chuck or collet before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or lubricant when countersinking ferrous metals to extend tool life and improve finish. Inspect the cutting edges before each use and remove from service if chipping or dullness is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112812\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: 28628\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51695723446578,"sku":"28628","price":32.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4131417be42b466f9c16e311489040b4.jpg?v=1788337767","url":"https:\/\/voomisupply.com\/products\/value-collection-28628-countersink-1-2-in-82-degree-6-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
