With a 0.25 inch head diameter, a 60-degree included angle, and four flutes, this tool delivers consistent cutting geometry and efficient chip evacuation in demanding machining applications. The straight cylindrical shank measures 0.25 inches in diameter for standard collet or chuck mounting. It is suited for machinists, tool-and-die shops, and production environments where precise countersinking at tighter tolerances is required.\u003c\/p\u003e\n\u003cp\u003eThis countersink is used in metalworking and manufacturing applications where 60-degree conical seats are needed, such as deburring drilled holes or preparing fastener seats in ferrous and non-ferrous workpieces. The four-flute configuration reduces chatter and improves surface finish compared to single-flute designs. It is appropriate for use in CNC machining centers, manual mills, and drill press setups across job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25 inch head diameter for compact countersinking in tight clearance areas\u003c\/li\u003e\n  \u003cli\u003e60-degree included angle for standard fastener seat preparation\u003c\/li\u003e\n  \u003cli\u003eFour-flute geometry reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard collets and drill chucks\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 standard 0.25 inch straight-shank toolholders in CNC and manual machining setups requiring a 60-degree countersink profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the straight shank firmly in a collet or drill chuck rated for the spindle speed being used. Ensure the machine is fully powered down and the spindle is locked before changing tooling. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life and surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eMaterial\u003c\/strong\u003e: Carbide\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: 334-003050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754615046450,"sku":"334-003050","price":41.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2aa0f591cd9edb7f12c1cf8e07aa178.jpg?v=1788947133","url":"https:\/\/voomisupply.com\/products\/hertel-334-003050-carbide-countersink-1-4-in-60-deg-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
