Built from high speed steel, this tool delivers reliable performance in metal fabrication, machining, and general holemaking applications. It features a 13\/32-inch cutting diameter, a 17\/64-inch pilot diameter, and a 2-flute geometry that promotes clean chip evacuation and smooth cutting action. The 1\/4-inch shank diameter fits standard tool holders and drill chucks used in machine shop and production environments. Licensed machinists and tooling specialists are the primary users of this type of counterbore.\u003c\/p\u003e\n\u003cp\u003eThis counterbore is sized to work with 1\/4-inch socket-head cap screws, making it a common choice for applications that require recessed fastener seating in steel, aluminum, and similar workpiece materials. With an overall length of 3.5 inches and a 1\/4-inch shank, it fits typical drill presses, milling machines, and CNC machining centers. The solid pilot design provides precise hole alignment and reduces chatter during the counterboring operation. It is well suited for production runs and maintenance machining tasks where consistent fastener seat geometry is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n \u003cli\u003e13\/32-inch cutting diameter for socket-head cap screw seating\u003c\/li\u003e\n \u003cli\u003e17\/64-inch solid pilot for accurate hole alignment and reduced chatter\u003c\/li\u003e\n \u003cli\u003e2-flute geometry promotes clean chip removal and smooth cutting\u003c\/li\u003e\n \u003cli\u003eHigh speed steel construction provides durability in ferrous and non-ferrous materials\u003c\/li\u003e\n \u003cli\u003e1\/4-inch socket-head cap screw compatible sizing\u003c\/li\u003e\n \u003cli\u003e3.5-inch overall length suits standard machine tool setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use solid pilot counterbore compatible with 1\/4-inch socket-head cap screws.
