Built with a straight-cylindrical shank measuring 0.25 inches in diameter and a head diameter of 0.5 inches, this tool mounts directly into standard drill chucks or collet holders. The right-hand cutting direction and bright uncoated finish make it a straightforward, no-frills option for general countersinking work in metal, wood, and composite materials. Licensed machinists, tool-and-die technicians, and maintenance professionals reach for this style of countersink when a clean, accurate chamfer is required without the complexity of multi-flute chatter.\u003c\/p\u003e\n\u003cp\u003eThis countersink is suited for use in manual drill presses, CNC machining centers, and hand-held power drills where a 0.25-inch straight shank is accepted. The 100-degree included angle is commonly specified for aerospace and sheet-metal fastener seating, particularly for flush-head screws and rivets that call for a wider-angle seat than the more common 82-degree or 90-degree profiles. Single-flute geometry reduces chatter on thin-wall workpieces and softer metals. It ships individually and is sold in a minimum quantity of one unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e100-degree included angle (50-degree centerline angle) suits wide-seat fastener applications\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design minimizes chatter on thin-wall and soft-material workpieces\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides good wear resistance across general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 0.25-inch shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003e0.5-inch head diameter handles a range of common fastener sizes\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows easy visual inspection of cutting edge condition\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink for use in any machine tool or hand-held drill accepting a 0.25-inch straight-cylindrical shank; no pilot included and no pilot required for standard countersinking operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or experienced technician should secure the shank firmly in the chuck or collet before operation, verifying runout is within acceptable limits for the application. Always power down and lock out the machine before changing or inspecting the tool. Feed rate and spindle speed should be set according to the workpiece material and tool manufacturer recommendations for high-speed steel cutters. Wear appropriate eye protection and ensure the workpiece is properly clamped before beginning the countersinking operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 100 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenterline Angle\u003c\/strong\u003e: 50 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\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: 0.25 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\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\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: SC10100032\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716404150578,"sku":"SC10100032","price":20.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33549d0787fa9e2fa53bd8f1df65c974.jpg?v=1788525519","url":"https:\/\/voomisupply.com\/products\/value-collection-sc10100032-countersink-100-deg-1-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
