Description

The B157 chucking machine reamer from Dormer is precision ground with a high spiral left hand helix and right hand cutting action, giving you great performance, particularly when machining stainless steel, whilst the premium High Speed cobalt from which it is manufactured makes it suitable for reaming many other materials including steels and aluminium. The tapered lead makes it easy to locate and centre, ensuring better performance and hole quality, with a hole finished within the limits of H7 hole tolerance. With a straight shank, the B157 will give you high performance reaming when used in CNC machines.
