PFERD Tough Burs

For heavy-duty applications in shipyards, foundries and steel construction, PFERD has developed two new special cut patterns for its tungsten carbide burs.

The new 3R and 3RS cuts represent a new PFERD product line designed especially for tough operating conditions. These tungsten carbide burs are characterized by their exceptional impact resistance and performance. The new cuts are ideal for all uses involving high mechanical shock or impact loads. Susceptibility to tooth chipping/breakage, splintering and bur head cracking has been effectively minimized.

Even when milling at low RPM with an only moderately powerful machine, the occurrence of tooth failures is dramatically reduced.
