Armeg Adjustable Hole Cutter 40 to 200mm

The clear polycarbonate dust shield has two main functions. It collects debris, dust and chippings, which is particularly important when working overhead. It also acts as a guide ensuring that the drill bit is always at right angles to the work surface. The boring head passes through a large ball race bearing so runs very smoothly. Two cutters, one on each of the graduated arms gives you a balanced performance minimising vibration. The cutting depth is adjustable up to a maximum of 46mm. The ability to bore holes from 40 to 200mm diameter allows you great versatility. Use with a variable speed drill, the larger the diameter the slower the speed.
