IRWIN 1882792 TAPERED COUNTERSINK 8PC SET

The IRWIN Speedbor Countersink Wood Drill Bit set features an innovative design that is essential for any woodworking project. This eight-piece set includes bits with a 1/4″ quick-change shank, ensuring a secure fit in standard chucks and compatibility with impact drills, which minimizes slipping during use. The tapered drill bits are specifically crafted with widened flutes to create clean and fast pilot holes, while the adjustable four-cutter counterbore cuts and efficiently clears chips, leading to smoother countersinks. With a secure attachment mechanism using two hex screws for the counterbore, users can also easily control pilot hole depth, making this set a versatile addition to any toolkit.
