Drill guides are portable fixtures designed to provide mechanical guidance for drill bits, ensuring precise and straight—or intentionally angled—holes in a wide range of materials. By stabilizing the bit and preventing wandering, they deliver drill press-level accuracy without the need for a dedicated drill press. This makes them particularly valuable in woodworking, cabinetry, and DIY applications. In use, a drill guide is mounted onto a standard handheld drill, while the workpiece is secured in place. The guide’s columns and chuck then control the drill bit, allowing it to enter the surface perpendicularly or at a chosen angle, ensuring clean, consistent, and professional-quality results.
