This round brush with its knotted design adapts itself to the contours of every workpiece due to its elasticity. The knotted brushes are much more durable than the corrugated type and are therefore designed for extreme brushing requirements. Thanks to its 22.23 mm bore, the brush can be used with any commercially available angle grinder. This brush can be used for many different tasks such as deburring, descaling, derusting, cleaning, fettling, roughening and paint stripping. The brush is made of high-performance steel wire with a high tensile strength. This gives this round brush an excellent tool life and eliminates the need for frequent tool changes. They are used where residues of normal steel wire would adversely affect the machining metal surfaces such as stainless steel, aluminium and other non-ferrous metals (not iron). Technical brushes can be used with both stationary machinery as well as with handheld power tools. Regular testing ensures a high degree of reliability.
