We turn this heavy driver with an 8 mm shank and an 18 mm head for screws that demand more purchase than a standard movement driver allows. The ball bearing in the head lets downward finger pressure stay steady while the knurled body turns. A conical 1.60 mm blade sits locked by a side screw.
Wide swivel head
The 18 mm head runs on an internal ball bearing. Your index finger rests on a broad, smooth disc that remains stationary while the barrel rotates underneath, keeping downward force centred on the screw slot.
Heavy knurled shank
We turn the body to an 8 mm diameter from stainless steel. Deep knurling cut directly into the metal gives dry fingers positive traction when loosening case screws, bridge screws, or tight lug pins.
Conical blade profile
The 1.60 mm blade is formed from hardened stainless steel with a conical taper. It seats deep into matching screw slots to distribute turning force across the full width of the cut.
Screw blade retention
A set screw threaded into the lower barrel locks the blade firmly in place. When the edge wears down or chips, loosen the set screw to dress the flat on an oilstone or fit a replacement.

A note that touches this tool
Reading a catalogue number
What the parts of a Bergeon reference number mean, why the number is how a tool is asked for, how a suffix marks a size or a variant of the same family, and how to find the spare blade for a handle you already own.
Choosing a blade width
Why a screwdriver is chosen by the width of its blade rather than by its name, what happens to a screw head when the blade is a step too narrow, how the blades are stepped through the range, and how a worn blade is dressed or swapped.
