BRUKO Tools

BRUKO flexible polyurethane tools are designed for grinding
and polishing metals. The tools are filled with highly abrasive
material. They are mostly used dry,
but it is possible to use a cooling medium (recommended
pH 7).
The tools are manufactured in various sizes and shapes.
Types A1, A2 and C1 are glued to shanks with a diameter of 3
and 6 mm or 2.35 mm. Type B1 is a disc with a center bore.
