Wiha 26390 Hex Metric Screwdriver Set - Precision Small Bits

In this review of the Wiha 26390 screwdriver set, the bottom line is simple: it is a precision tool kit for anyone who needs reliable small hex drivers. The set stands out because of its exact-fit, precision-machined tips and ergonomically designed precision handle that allow controlled fingertip turning and rapid rotation. For hobbyists repairing RC gear, electronics technicians, or anyone working with metric hex fasteners from 0.7 to 3.0mm, this set delivers consistent fit and durable construction that justify its purchase.

Key Features

• Precision tips: Precision-machined and ground tips provide an exact fit that reduces cam-out and protects small fastener heads.
• Range of sizes: Includes 0.7, 0.9, 1.3, 1.5, 2.0, 2.5 and 3.0mm, covering the common small metric hex sizes used in electronics and models.
• Ergonomic handle: Molded tapered cushion grip with a rotating cap allows rapid rotation and fingertip control for precise torque application.
• Durable blades: Blades are made from hardened chrome-vanadium-molybdenum steel with chrome plating for wear resistance and longevity.
• Easy identification: Tip profile labeled on the handle makes it quick to pick the right size during repetitive tasks.

Who It's For

This set is ideal for electronics hobbyists, model builders, and technicians who frequently work with small metric hex screws and need a durable, precise driver in compact sizes. The extra-long handle options in the set suit tasks where reach or varied hand positions improve access and control.

Anyone needing larger screwdrivers, interchangeable bit systems, or a cheaper disposable option should look elsewhere; this set is positioned for repeated use and precision rather than occasional low-cost replacements.

Pros & Cons
