Designed for woodworkers, DIY enthusiasts, and professional craftsmen who need error drilling accuracy across woodworking projects and multiple applications. 2.5 specifications of vertical drilling holes can be used with corresponding specifications of drilling bit to assist in positioning and drilling. The embedded level bubble design helps with hanging pictures, installing shelves, and achieving level decor. Optimizes drilling tasks on workshop benches, for home jobs, or circular pipe installations while maintaining stability on slippery or uneven surfaces. Practical applications Mounting a gallery wall or picture rail: use the vertical hole specifications to position multiple drill points consistently for straight, evenly spaced results. Cabinet and shelf installation: align and drill vertical holes accurately on workbenches or mounted surfaces to ensure sturdy, square assemblies. Circular pipe or conduit installations: perform precise drilling tasks for round piping projects while keeping the setup stable on uneven floors or work surfaces.
