HK - KOTI square brushes are ideal for use in locations where interior brushes are unsuitable due to their design, such as the bottom of a borehole. They are capable of machining the flanks and bottom of boreholes (blind holes) simultaneously. They are available with a diameter of 16-90 mm and with the whole range of different filler materials.
These brushes enable efficient and economical bushing of the blind hole base, while simultaneously processing the flanks. This makes for significant time savings. Simply let us know your requirements.
