Wiha 28393 Insulated SlimLine Ultra-Driver Set – Slotted & Phillips, 10kV Tested

Precision and safety in a slim, easy-to-use screwdriver set

The Wiha 28393 SlimLine Ultra-Driver brings a compact blade profile together with a comfort-focused SoftFinish handle, designed for professionals and serious DIY enthusiasts. This seven-piece set covers both slotted and Phillips tasks, featuring four slotted blades (3.0, 4.0, 5.5, 6.5 mm) and two Phillips tips (#1 and #2). The slim blades slide into tight spaces with full blade exposure for fast, accurate driving, while the rotating cap allows steady palm pressure for improved control.

One of the standout design choices is the SlimLine insulation, which is 33 percent narrower in diameter than standard insulated tools. This slimmer profile helps you reach screws in crowded panels, cabinets, or electrical enclosures where bulk can get in the way. The blade chamber pops up with a squeeze, making bit changes quick and simple, and a friction fit O-ring blade holder keeps blades secure during use. A locking blade holder ensures every SlimLine blade remains safely stowed when not in use.

Safety and standards are at the core of this set. Each blade is individually tested to 10,000 volts AC and rated to 1,000 volts AC (1,500 volts DC) for dependable protection during high-stakes tasks. The insulation complies with EN/IEC 60900, ASTM F-1505-01, VDE 0682 part 2012, DIN 7437, NFPA70E, and CSA specifications, reflecting a broad commitment to safety across international guidelines. These features work together to support confident, controlled screwdriving in electrical environments without making promises about outcomes.
