Screwdrivers Microfinish
Screwdrivers
Wiha MicroFinish screwdrivers are characterised by a large handle diameter that delivers high torque with low physical effort. The range includes nine versions: slotted (blade widths 4.5 to 10 mm) and cross-head (PH1, PH2, PH3). Blade lengths run from 90 mm (4.5 mm blade) to 175 mm (10 mm blade). Handle diameters are 30 mm (4.5-6.5 mm blades) or 41 mm (8-10 mm blades). A 9-piece set (29138) covers the main sizes. Blades are chrome-vanadium steel.

The MicroFinish series is aimed at applications where high torque must be applied manually without a long blade becoming a hindrance. The large handle diameter (up to 41 mm) allows large fasteners to be tightened without excessive wrist strain. Slotted versions from 4.5 mm suit machine screws; PH1-PH3 cover cross-head connections in assembly work. The 9-piece set (29138) is the most economical starting point for the MicroFinish line.
Typical applications: machine assembly and maintenance with larger screw diameters (slotted 4.5-10 mm), switchgear assembly and terminal connection (PH1-PH3), workshop and repair tasks requiring high torque, trade use in wood and metalwork, and service work where a large handle diameter provides an ergonomic advantage.
