The portable drilling machine's guide bracket is equipped with ball-bearing guide rods for smooth up and down movement. It is compatible with a half inch chuck and can accommodate various drill bits. The all-metal base enables precise control of the drilling depth and supports vertical and inclined drilling. The split structure is lightweight and easy to store. It provides accurate positioning for woodworking and home decoration drilling, and even beginners can drill standard holes.

Standardly equipped with a large-sized 1/2-inch chuck, it has a wide clamping range. It can securely lock and hold round shank, square shank twist drills, hole punchers, and countersink drills. The clamping is firm and does not slip. The operation of removing and installing drill bits is simple. No additional conversion accessories are required. It is compatible with household electric drills, impact drills, and lithium-ion drills. This set of brackets is compatible with most of the drilling operations in daily life.This portable drilling guide bracket, equipped with ball-bearing guide rods and a 1/2-inch large chuck, can transform a handheld drill into a vertical bench drill, allowing for precise control over the verticality and depth of the drilling. It is suitable for woodworking, hardware installation, and home improvement drilling.
The inner part is equipped with ball-bearing guide rods, ensuring smooth up and down movement without any jamming.
The two thickened metal guide rods are integrated with a ball-bearing structure. The entire up and down movement is smooth and without resistance, and the force is evenly distributed without deviation. The spring's automatic rebound design ensures that the bracket automatically lifts after releasing the handle, eliminating the need for manual resetting during continuous drilling. The bearings are wear-resistant and durable, ensuring that there will be no shaking or sticking problems during long-term high-frequency operation, and guaranteeing the verticality of each drilling. The multi-angle adjustable base allows for precise control of the drilling depth.
The base is equipped with multiple sets of positioning installation holes, and when paired with the corresponding limit support, it can fix the board to prevent sliding. The two black anti-slip operation handles on both sides provide stable force application. The body is equipped with a depth scale ruler, allowing for the pre-locking of the drilling depth to avoid drilling through the workpiece. The base supports fine adjustment of the angle, enabling both vertical straight holes and inclined positioning holes to be processed, meeting diverse processing needs.
The entire metal thickened body is made of aluminum alloy, which is portable, durable, and easy to store.
The bracket body is formed by an integrated die-casting of aluminum alloy, with anodized anti-rust and wear-resistant properties. It has strong load-bearing capacity and is not prone to deformation. The overall split structure is easy to disassemble and assemble, and it does not need to be fixed on the workbench. It can be used for handheld or tabletop operations. It can be carried and stored when going out for installation. It can be used for drilling on boards, assembling furniture, opening holes for hardware, and processing windows and doors. Even beginners can drill flat and standard holes, reducing material waste.
