Take full control of your drilling depth with this set of 8 adjustable drill bit depth stop collars from STONEGO. Whether you are boring hinge holes, dowel joints, or repeated pilot holes, these positioners let you lock a precise depth so every hole matches the last one.
Made from durable carbon steel with a black finish, each collar uses a setscrew design that grips the bit firmly without chewing up the shank. The split-ring style clamps evenly around the bit, so you can slide and lock it anywhere along the length for fast, repeatable setups.
Supplied with a hex wrench for quick adjustments, this 8-piece set is a practical addition to any woodworking bench, drill press, or hand-tool kit.
Ideal for precision woodworking tasks such as dowel joints, hinge recesses, pilot holes, and any job where drilling too deep would ruin the workpiece. Simply slide the collar onto the bit, set your depth, and tighten with the supplied hex wrench.
Suitable for hobbyists, cabinet makers, furniture builders, and anyone who drills repeated holes and wants a consistent depth every time.
