Up to 45 cm long, this set of four long T-handle drivers is a perfect tool kit for working with fasteners that are hard to reach. The set is made of a chrome-vanadium steel alloy that is durable and resistant to deformation; each tip is hardened for extra strength. The magnetic tips helps with fast and precise work on fasteners, especially where they cannot be reached with fingers. The ergonomic handle is comfortable to use and requires little effort to operate the driver. The non-slip surface finish helps with precise working and allows full force transfer to the fastener. The purposeful design makes it easer to work with stubborn fasteners, featuring flats which can accommodate a spanner for extra leverage.
