Built from high speed steel, this tool delivers consistent cutting performance across standard machining and fabrication tasks. The 100-degree included angle suits flat-head fastener seating in applications where that geometry is specified. With a 1\/4-inch head diameter and a 1\/4-inch straight cylindrical shank, it fits directly into standard drill chucks and collet holders without adapters. Machinists, tool and die workers, and maintenance technicians use this countersink for deburring, chamfering, and fastener-seat preparation on light-duty workpieces.\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 1\/4-inch shank is accepted. It is appropriate for metalworking, sheet metal fabrication, and general maintenance applications requiring a precise 100-degree chamfer. The single-flute geometry reduces chatter on softer metals and produces a smooth finish in shallow countersink operations. It is sold individually and is a practical addition to a standard machining tool kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-inch head diameter for compact countersinking in tight clearance areas\u003c\/li\u003e\n  \u003cli\u003e100-degree included angle for flat-head fastener seating where that specification is required\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design reduces chatter and promotes smooth cutting on softer metals\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across general machining tasks\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-flute countersink for use in any drill press, machining center, or hand-held power drill that accepts a 1\/4-inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank firmly in a drill chuck or collet before use and verify the tool is fully seated to prevent runout. Power down the machine and disconnect or lock out the power source before installing or removing the countersink. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Follow applicable shop safety standards and wear eye protection during all machining operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1\/4 inches\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\u003eIncluded Angle\u003c\/strong\u003e: 100 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 18013\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51729276895538,"sku":"18013","price":52.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a4d068d062a352e69fdab51f39d257c8.jpg?v=1788702392","url":"https:\/\/voomisupply.com\/products\/hertel-18013-countersink-1-4-in-hss-100-degree-1-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
