The Irwin Speedbor Replacement Countersink Bit is a tapered drill bit designed for drilling fast, clean pilot holes in wood. This replacement bit features widened flutes that work with an adjustable four-cutter counterbore to enable smooth countersinking. It works with your existing quick-change chuck system, making it easy to swap out when you need a fresh cutting edge.
The counterbore attaches to the shank flats with two hex screws for a secure fit and can be adjusted for controlled pilot hole depth. Whether you're doing DIY work or professional fastening, this bit delivers the pilot hole and counterbore function you need in a single tool.
