With a 1\/2-inch head diameter and an 82-degree included angle, it matches the standard seating angle used by most imperial flat-head machine screws and wood screws. The 3-flute geometry promotes smoother cutting action and reduces chatter compared to single-flute designs. The body is manufactured from high speed steel, providing adequate hardness for general-purpose drilling into aluminum, mild steel, wood, and plastics. The 3\/8-inch shank diameter fits standard drill chucks and quick-change holders used in hand drills and drill presses.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for light fabrication, assembly work, and general maintenance tasks where a clean, properly angled fastener seat is required. It is commonly used in metal fabrication shops, electrical panel assembly, plumbing rough-in work, and general mechanical service. The 82-degree angle matches ANSI flat-head fastener standards, making it a practical choice for technicians working with standard imperial hardware in a wide range of materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-inch head diameter for moderate-size countersink profiles\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches standard imperial flat-head fastener geometry\u003c\/li\u003e\n  \u003cli\u003e3-flute design reduces chatter and improves surface finish quality\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles aluminum, mild steel, wood, and plastics\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank fits standard drill chucks and quick-change holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink compatible with standard 3\/8-inch chuck drill presses, hand drills, and drill\/driver setups where an 82-degree flat-head fastener seat is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a drill press or hand drill with a 3\/8-inch or larger chuck. Use appropriate cutting speed for the workpiece material — lower speeds are recommended for steel, higher speeds for aluminum and wood. Secure the workpiece firmly before operation to prevent movement. Wear appropriate eye protection and ensure the cutting tool is fully seated in the chuck before applying power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1\/2 inch\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\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: 28617\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692512379186,"sku":"28617","price":24.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a6a2f8229dd8b3c2d2aec24bda98f0d.jpg?v=1788298681","url":"https:\/\/voomisupply.com\/products\/value-collection-28617-countersink-1-2-in-82-deg-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
