Drill Bit Extension with Key 3/8 Hexagonal Shank Design for Wood Spade Drill Bit, Electric Tool Accessories(Aperture 7.1mm/0.28in Length 300mm/11.81in)

Feature:【Extended Working Range】The main function of the drill bit extension is to extend the working range of the drill, allowing you to easily drill in hard-to-reach or space-constrained areas. This feature greatly widens the working area and increases flexibility and efficiency.【Steel Material】The drill bit extension is made of steel, which has high hardness and good abrasion resistance, and can withstand large cutting force and impact, without being easily deformed or damaged. The strength and stability of steel makes the extension to keep stable performance in the bad working environment, which is not easy to loosen or fall off and ensure the smooth running of the work.【Hexagonal Shank】Adopting 9.5mm (3/8in) hexagonal shank design, it has larger contact area and more stable structure. This design can effectively prevent loosening or dislodging when rotating at high speeds, and ensure that the extension rod is tightly connected to the drill rig or electric drill, enhancing the safety and efficiency of the operation.【Convenient To Use】The use process is simple and quick, without complicated steps. First, use the hexagonal key included in the package to loosen the set screws, then insert the drill rod (not included) into the extension bar, making sure that the two set screws are parallel to the flat surface of the drill rod, and finally tighten the two set screws.【Specification】We offer two lengths of extension rods, including 150mm/5.91in and 300mm/11.81in. The extension rods are available in different aperture sizes, which can be adapted to different sizes of drilling rigs to meet a variety of operational needs.
