With a 1-1\/2 inch head diameter and an 82-degree included angle (41-degree centerline angle), it produces clean, accurate countersunk profiles for flat-head fasteners. The six-flute geometry distributes cutting load evenly, reducing chatter and extending tool life in harder workpiece materials. The bright, uncoated finish suits general-purpose countersinking without added coating thickness. Machinists and toolroom technicians are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for use in manual machining centers, drill presses, and CNC equipment where precise countersink geometry is required. The straight cylindrical 3\/4 inch shank accepts standard tool holders and collet chucks. Right-hand cutting direction is standard for conventional spindle rotation. The 82-degree angle matches the seating geometry of most imperial flat-head machine screws and aerospace-style fasteners. No pilot is included, so a separate pilot or starting hole is required before use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch head diameter for large-diameter countersink seats\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle matches standard flat-head fastener seating geometry\u003c\/li\u003e\n  \u003cli\u003e6-flute design reduces chatter and promotes smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCobalt steel construction provides heat and wear resistance in harder materials\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch straight cylindrical shank fits standard collet chucks and tool holders\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating tolerance buildup at cutting edges\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in drill presses, manual mills, and CNC machining centers equipped with a 3\/4 inch collet or tool holder capable of accepting a straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and used by machinists and toolroom professionals. Secure the shank fully in a properly sized collet or chuck before operation and verify runout is within acceptable limits. Pre-drill a pilot hole to the required minor diameter before engaging the countersink. Follow machine tool manufacturer guidelines for spindle speed selection based on 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: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 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\u003eEnd Type\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePilot Included\u003c\/strong\u003e: No\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\u003eTool Application\u003c\/strong\u003e: Countersinking\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.075 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: SC2182132\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718741754162,"sku":"SC2182132","price":169.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8dff838458d89078873de6c096fb82ff.jpg?v=1788555300","url":"https:\/\/voomisupply.com\/products\/value-collection-sc2182132-countersink-1-1-2-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
