Built from high-speed steel with a bright uncoated finish, it features a 60-degree included angle and three flutes for efficient chip evacuation during right-hand cutting operations. The 1\/4-inch straight-cylindrical shank fits standard drill chucks and quick-change holders. With a 3\/8-inch head diameter, this countersink is sized for common fastener seating applications in light-to-medium machining work. No pilot is included, so the operator controls centering through technique or a pre-drilled guide hole.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for machinists, tool and die techs, and maintenance professionals working on deburring, fastener seating, and edge-chamfering tasks. The 60-degree included angle matches common flat-head screw geometries used in general metalworking and fabrication. Its compact head size and standard 1\/4-inch shank make it compatible with bench drill presses, hand drills, and CNC spindles running right-hand rotation. Typical applications include sheet metal, aluminum, mild steel, and similar workpieces where a clean countersunk seat is required before fastener installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60-degree included angle suits flat-head fastener seating in metalworking applications\u003c\/li\u003e\n  \u003cli\u003eThree-flute design promotes chip clearance and a smoother finished seat\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across common metals and alloys\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight-cylindrical shank fits standard drill chucks and quick-change systems\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows visual wear inspection during service life\u003c\/li\u003e\n  \u003cli\u003eSingle-end, no-pilot design offers flexibility across pre-drilled hole sizes\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, hand drills, and CNC spindles requiring a 1\/4-inch straight shank and right-hand cutting rotation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using standard drill press or hand-drill setups. Secure the workpiece before operation to prevent movement during countersinking. Run at appropriate spindle speeds for the workpiece material — lower speeds are generally recommended for harder metals. Inspect the cutting edges before each use and replace when wear causes chatter or an uneven seat profile.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003ePilot Included\u003c\/strong\u003e: No\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: 0.06 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: SC4060024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689704948018,"sku":"SC4060024","price":18.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50a794b18c0af053635cc953d5d0cda9.jpg?v=1788263265","url":"https:\/\/voomisupply.com\/products\/value-collection-sc4060024-countersink-60-deg-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
