It features a 1\/4 inch head diameter, an 82-degree included angle, and 6 flutes for smooth, chatter-resistant cutting. The straight cylindrical shank measures 1\/4 inch in diameter for direct chuck mounting. Cobalt steel construction provides elevated heat resistance compared to standard high-speed steel, making this tool suitable for harder ferrous and non-ferrous materials. The bright, uncoated finish keeps the tool ready for use without additional prep. Machinists, tool and die workers, and mechanical assembly technicians are the primary users of this type of countersink.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for hand-drill, drill press, and CNC or manual lathe work where flat or machine screw head seats need to be formed. The 82-degree included angle matches the standard flat-head machine screw geometry common in aerospace and general industrial fastener applications. It is appropriate for use in mild steel, stainless, aluminum, and similar machinable materials. The single-end design and compact 1\/4 inch head make it practical for close-tolerance work and confined locations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree included angle matches standard flat-head fastener seat geometry\u003c\/li\u003e\n  \u003cli\u003e6-flute design reduces chatter and produces a cleaner seat finish\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction handles higher cutting temperatures than standard HSS\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch straight cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish requires no break-in and works with cutting fluid\u003c\/li\u003e\n  \u003cli\u003eSingle-end tool with no pilot pin for flexible positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3-jaw drill chucks and collets accepting a 1\/4 inch straight shank.

Use appropriate cutting fluid for steel and stainless applications to extend tool life. Run at a lower RPM than equivalent twist drills of the same diameter to reduce heat buildup. Inspect the cutting edges before each use; cobalt steel is harder than standard HSS but can chip if subjected to impact or excessive feed pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 41 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes Pilot\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Countersinking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0333 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: SC2182016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711931318578,"sku":"SC2182016","price":23.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfa59b0354069ffe6f40359266de9a0b.jpg?v=1788481539","url":"https:\/\/voomisupply.com\/products\/value-collection-sc2182016-countersink-1-4-in-82-deg-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
