With a 1 inch head diameter and an 82-degree included angle, it produces consistent seat geometry for flathead fasteners. The 6-flute design distributes cutting load evenly, reducing chatter and extending tool life compared to fewer-flute designs. The straight cylindrical shank measures 0.5 inches in diameter, fitting standard drill press and CNC collet chucks. It arrives with a bright, uncoated finish and is suited for use by machinists, maintenance technicians, and fabricators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used in metalworking and general fabrication applications where 82-degree flathead screw seats are required. It is compatible with ferrous and non-ferrous metals, and the cobalt steel construction provides added heat resistance for drilling harder alloys. The straight-cylindrical shank accepts standard 0.5 inch collets and drill chucks without an adapter. Typical applications include countersinking pre-drilled holes in steel plate, aluminum extrusions, and structural components prior to flathead fastener installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch head diameter with an 82-degree included angle for standard flathead fastener seating\u003c\/li\u003e\n  \u003cli\u003e6-flute geometry reduces chatter and provides a smooth, consistent finish\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction resists heat buildup when cutting harder ferrous alloys\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical 0.5 inch shank fits standard collets and drill chucks\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating delamination risk in interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with no pilot pin for use in pre-drilled holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use countersink for metalworking operations requiring an 82-degree included angle and a 0.5 inch straight-cylindrical shank in standard drill press, mill, or CNC collet setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified fabricator should install this tool in a drill press, milling machine, or CNC spindle using a properly sized collet or chuck. Power down and lock out the machine before inserting or removing the tool. Use cutting fluid appropriate to the workpiece material to extend tool life and improve finish quality. Do not exceed the spindle speed recommended for the workpiece material and tool diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1 inch\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\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeight\u003c\/strong\u003e: 0.0236 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: CS2160100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694472397106,"sku":"CS2160100","price":80.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eca02b74f1585ee720ad54cae185c466.jpg?v=1788324658","url":"https:\/\/voomisupply.com\/products\/value-collection-cs2160100-countersink-1-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
