Machined from zirconium for the body and black timascus for the bearing housing
A little more information on this product:
New to my product line, these 4" long hex bit drivers accept and utilize standard 1/4" hex inserts. They have a hybrid stainless/ceramic bearing within the "bearing housing" or "bearing house" at the end of the handle allowing the driver to rotate or spin in your hand while you go about your work and fasten or unfasten your screws.
While in use, the Hex bits are retained in the driver via neodymium rare earth magnets.
Designed to be a precision screwdriver for adjusting or working on items like watches, eye glasses, pocket knives or any other component with very tiny hardware.
Included with the driver are 12 premium Wiha hex bits: 3 Philips bits (#1, #2, #3) 3 Flathead bits (4.5, 5.5, 6.0) 6 Torx bits (T5, T6, T7, T8, T9, T10)
