Built from high speed steel (HSS) with a bright, uncoated finish, this tool delivers clean, flat-bottomed recesses for cap screw seating. The counterbore measures 0.412 inches in diameter with a 9\/32 inch pilot diameter, classified as an oversize pilot for guided, accurate entry. The 4-flute configuration promotes smooth chip evacuation and a consistent finish. With a 5\/16 inch shank diameter and an overall length of 5.625 inches, it fits standard drill press and milling machine chucks used in production and maintenance environments. Machinists, toolmakers, and mechanical contractors are the typical end users.\u003c\/p\u003e\u003cp\u003eThis counterbore is compatible with 1\/4 inch cap screws and is suited for creating properly dimensioned recesses that allow fastener heads to sit flush or below a workpiece surface. It is appropriate for use in light to medium machining on ferrous and non-ferrous metals where HSS tooling meets the application requirements. The oversize pilot provides additional clearance over standard pilot counterbores, making it useful in rework and repair scenarios where hole tolerances may vary slightly from nominal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.412 inch counterbore diameter for 1\/4 inch cap screw compatibility\u003c\/li\u003e\n\u003cli\u003e9\/32 inch oversize pilot diameter for guided entry and alignment\u003c\/li\u003e\n\u003cli\u003e4-flute design for efficient chip removal and surface finish quality\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003e5\/16 inch shank diameter fits common drill press and milling chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1\/4 inch cap screws.
