Saburr Tooth burrs from America are a revelation in sculpting, shaping or smoothing wood, fibreglass, rubber, foam or silicone. They are very durable and aggressive but controllable and resistant to clogging. Long lasting, razor-sharp carbide cutting teeth are arranged into a unique open pattern to resist "loading" while providing the "Power Carver" rapid stock removal and smoother finishes. They are available in many shapes, sizes and grades to suit your carving, grinding, cutting and machining needs. These sanding sleeves are available in a range of diameters at 50mm long and are designed to fit the matching size of mounting mandrel. For safety, always use approved eye protection and safety devices. Please note: not suitable for use on metals or ceramics.
