The tapered drill features widened flutes engineered to clear chips quickly and produce fast, clean pilot holes in wood. A 4-cutter adjustable counter bore seats flush or recessed fasteners cleanly and adjusts for controlled pilot hole depth by securing to the flats on the shank via hex screws. The 1\/4 inch quick-change shank reduces slipping in standard chucks and is compatible with all 1\/4 inch quick-change chuck systems, including impact drivers. Suited for fine woodworking and general wood fastening applications.\u003c\/p\u003e\u003cp\u003eThis countersink set is designed for woodworkers, finish carpenters, and general contractors who need consistent, repeatable pilot holes for wood screws. The adjustable counter bore allows the installer to dial in pilot hole depth to match the screw length and material thickness, reducing the risk of splitting or over-driving. The widened flute geometry keeps the cut moving even in denser hardwoods, maintaining clean entry and exit around the countersink seat. The 6-piece pack suits job-site use where bit loss or wear is a routine consideration.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 6 tapered drill profile sized for standard No. 6 wood screws\u003c\/li\u003e\n\u003cli\u003e4-cutter adjustable counter bore for fast, smooth countersinking\u003c\/li\u003e\n\u003cli\u003eWidened flutes clear chips quickly for cleaner pilot holes\u003c\/li\u003e\n\u003cli\u003eCounter bore locks to shank flats with hex screws for controlled depth adjustment\u003c\/li\u003e\n\u003cli\u003e1\/4 inch quick-change shank compatible with standard and impact-rated chuck systems\u003c\/li\u003e\n\u003cli\u003eSold as a 6-piece pack for extended job-site use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with all 1\/4 inch quick-change chucks, including impact drills.
