The VALUE COLLECTION 30-641 is a wire-size drill stop designed to control drilling depth with precision on a Number 10 wire-size drill bit. Made from steel with a bronze finish, this collar-style stop clamps onto the bit shank and limits penetration to a set depth, preventing over-drilling in wood, metal, plastic, and composite materials. It is a compact, single-piece tool accessory used in production drilling, cabinetry, woodworking, and general metalworking applications where consistent hole depth is critical. At 0.05 pounds, it is lightweight and easy to install by hand or with a small hex key.
This drill stop is suited for use in residential and light commercial trade work, as well as shop and bench settings. Machinists, carpenters, electricians, and general contractors rely on depth stops when drilling repetitive holes to a fixed depth, such as setting shelf-pin holes, installing hardware, or pre-drilling for fasteners. The Number 10 wire size designation matches the bit diameter this stop is sized to fit, making sizing straightforward when ordering replacements or adding to a set.
Designed as an OEM-style depth stop for Number 10 wire-size twist drill bits used in standard drilling applications across woodworking, metalworking, and general construction trades.
Installation is performed by sliding the stop onto the drill bit shank at the desired depth mark and tightening the set screw with the appropriate hex key before use. Power down or unplug the drill before mounting or adjusting the stop. Do not overtighten the set screw, as this can damage the bit shank or cause the stop to seat off-center. Verify stop position against a depth reference before beginning production drilling runs.
