Confirmat Bits & Hollow Chisels

Our Confirmat bits and hollow mortising chisels are built for the precise, repeatable stepped-hole drilling that Confirmat fastening requires in cabinet and furniture assembly. Available in M2 high-speed steel and carbide-tipped construction, these V-point bits combine first-step, second-step, and countersink geometry in a single tool for clean, consistent results. We also stock hollow mortising chisel sets with center drill bits, along with replacement center drills sold separately.
