Round Tree carbide burrs: Often called a Christmas tree carbide burr as the sides are not parallel and the head of the burr has a rounded end cut face. Note: If you need the carbide burr to have a smaller diameter end cut profile then you may wish to look at the Flame Cut Burrs.

Diamond Cut Burrs – for stainless steel, steel, high carbon alloys, titanium, cobalt alloys etc and also for hardwoods Fluted Cut Burrs – for plastics and non-ferrous metals such as aluminium and brass and softwoods.
