Bosch PRO Impact 2608521U77 Screwdriver Bit Set (35 Piece) – 1/4" Hex Impact Rated

Bosch 2608521U77 PRO Impact is a 35-piece screwdriver bit set designed for tough screwdriving where durability matters, helping installers tackle demanding fixings with greater confidence. With an impact-rated 1/4" hex shank, it’s built for use in impact drivers and drill drivers.

This Bosch PRO Impact set uses heat-treated modified steel and a torsion zone to help absorb high torque at the bit tip, supporting longer bit life in heavy-duty applications. Colour-coded rings and laser markings make it quicker to identify the bit type and size during repetitive work.

Key Features
