Halls PB4 Powerbor Cutter & Pin Kit 5 Piece

Halls POWERBOR® cutters produce a solid slug of steel which is ejected when the cutter breaks through and the hole is complete. This reduces the problems experienced by the swarf and chips generated by conventional drilling. The cutters are ideal for cutting general engineering and structural steels, and they dramatically outperform conventional twist drills in terms of cutting speed and tool life. Each Powerbor cutter has a cutting depth of 25mm. The Kit contains the following: 5 x Powerbor cutters: 14mm, 16mm, 18mm, 20mm and 22mm.1 x Pin.
