Expand your DIY horizons: This set includes a convenient square chisel drill bit for drilling mortise holes (square and rectangular holes) for woodworking, furniture, and joinery. This woodworking drill bit perfect set answers the needs of those who prefer a set of commonly used sizes rather than the hassle of purchasing individual bits separately. Easily create pilot holes: Tenon joints are used in a variety of applications to create a strong joint between two pieces of wood at a 90-degree angle, but they can be considered a challenging process. Creating square or rectangular mortises, in particular, can seem like a daunting task, requiring both tools and skill. However, a square chisel drill allows for precise and speedy drilling. Wide range of compatibility: Compatible with all machines that use a drill chuck to secure round-shank bits, including manual and electric hand drills. Please note that this set is not compatible with sleeve-type bits, such as impact drivers, which only accept hexagonal-shank bits. Exceptional durability: Made with carefully selected hardened materials to prevent corrosion from heat and rust. It's also designed to allow wood chips to be discharged smoothly through the discharge throttle, significantly reducing work interruptions due to wood clogging and the time required for maintenance after use.
