Proxxon FLEX-DOT screwdriver handles are ergonomically designed ensuring excellent handling and ease of use. The two component handle has the ‘FLEX-DOT’ nubs for comfortable continuous use. The handle is also oil and acid resistant. Occasionally you need a screwdriver to tackle old or stubborn screws. These screwdrivers have extra strong hexagonal blades, matt-chrome plated with chrome-silicon-manganese-molybdenum alloyed special steel. An impact cap on the top of the handle means they can take a hammering.
