Constructed of tough tungsten vanadium, these Busch® concave burs cut fast and are self-clearing, keeping your workpiece clear of debris and easy to see as you cut. The dual chip channels designed into the bur head make the removal of cut material faster and safer. Their finer walls allow better access to closely spaced features such as prongs. The cutting surface also rounds as it shortens and polishes your metal.
This set includes 12 burs from 0.8mm through 2.0mm in 0.1mm increments.
