Wiha 7-Pc Phillips Insulated SlimLine Ultra-Driver Blade Slotted Set (28393) is a professional-grade insulated multi-bit screwdriver system designed for electricians and technicians who need high-voltage protection, slim access, and compact tool carry in one solution. Built around Wiha's SlimLine technology, this set reduces insulation diameter by 33% so the blade can reach recessed fasteners in tight electrical panels and terminal blocks more effectively than many standard insulated drivers. The Ultra-Driver handle also integrates an internal pop-up magazine that stores six interchangeable blades, allowing users to carry multiple insulated profiles in one organized tool while maintaining certified safety for energized applications. Key Features and Benefits: Integrated blade storage: Pop-up internal magazine stores six SlimLine blades, reducing the need to carry multiple full-size insulated screwdrivers. Certified electrical protection: Individually tested to 10,000V AC and rated for 1,000V AC or 1,500V DC for energized work. SlimLine access design: 33% narrower insulation profile helps reach deep-set screws and fasteners inside narrow electrical enclosures. Precision-machined tips: Exact-fit blade geometry helps reduce slipping, cam-out, and fastener damage. Dual-durometer ergonomic handle: Soft cushioned outer layer and rigid core improve comfort and torque transfer. Rotating cap control: Rear cap supports fine adjustment and controlled turning during detailed fastening work. Compact multi-profile system: Combines slotted and Phillips insulated blades in one portable driver platform. Direct-molded handle bond: Handle is molded directly to the blade holder for lasting structural integrity.

Select the required blade: Rotate the internal chamber until the needed slotted or Phillips blade is accessible. Remove the blade: Pull the selected blade out of its storage slot carefully. Insert the blade into the holder: Place the blade shank into the locking blade holder at the top of the handle until fully seated. Confirm secure engagement: Check that the blade is locked firmly before applying torque. Operate the screwdriver: Insert the tip fully into the fastener and use the rotating cap for controlled precision or the full grip for higher torque. Remove and store after use: Take the blade out, return it to its designated slot, and press the magazine back into the handle until it clicks shut. Inspect insulation regularly: Before energized work, check the handle and blades for visible damage or wear.
