Seventeen hardened-steel guide sizes, machined in 1/64-inch increments from nickel alloy steel, cover 1/8 to 3/8-inch bits and hold tight tolerances for perpendicular holes on flat stock, edges, and round bar. The V-groove centers the work on round materials, and the ground flat base sits securely on benchtops. Clamping is essential—the guide must be secured to the workpiece with a quick-clamp, as hand-holding may allow drift on slick woods. With that setup, the tool delivers drill-press accuracy and stands up to years of shop use, backed by a lifetime warranty.
This guide is for woodworkers, metalworkers, and committed DIYers who need portable perpendicular drilling without a dedicated drill press. It is not designed for pocket-hole joinery, angled holes, or anyone hoping to skip clamping—the tradeoff for its precision and 17-size convenience is an unconditional clamp requirement. For those willing to secure it firmly, the Big Gator pays for itself by eliminating rework from crooked holes.
💡 Use a quick-clamp or bar clamp to hold the guide firmly; even a small squeeze clamp keeps it from drifting on slick woods.
