Precision screwdriver set Kabelmeister TOOL-004 — 150 pieces, includes 117 C4 bits

Kabelmeister TOOL-004 is a precision screwdriver set containing 150 pieces, including 117 C4 bits. The set is designed to cover a broad range of small fasteners and connectors encountered in electronics repair, small appliance maintenance and hobby assembly work. Components are arranged for convenient access and the selection of bit types and sizes allows work on delicate and compact assemblies without excessive tool changes.

Advantages

The set offers an extensive assortment of bit types and sizes with a high proportion of C4 bits for consistent fit and torque transfer. Components are stored in an organized case for quick selection and safe transport. The precision drivers and bits are suitable for repeated use on small screws and provide controlled engagement to reduce the risk of cam-out or fastener damage. The variety of bits minimizes the need to buy separate tools for different tasks.

Suitable for

• Electronics repair and maintenance
• Smartphone, tablet and laptop disassembly
• Small appliance servicing
• Model making and hobby assembly
• General precision assembly tasks

Key specifications

• Total pieces: 150 (drivers, bit holders and bits included)
• Included bits: 117 C4 bits across multiple profiles and sizes
• Bit types: cross, slotted, Torx, hex, pentalobe and other precision profiles
• Drive sizes: precision driver shafts and compatible bit holders for small fasteners
• Storage: organized compact case with labeled compartments
• Material: hardened steel bits with corrosion-resistant finish for durability

How to use

Select a bit that matches the screw head profile and seat it fully in the bit holder or driver. Use the driver to apply steady, controlled torque while keeping the bit aligned with the screw axis to prevent slippage. For delicate components, apply minimal force and check threads or fastener condition before tightening. After use, return bits to their labeled positions in the case to maintain organization and protect the tips from damage.

Usage recommendations

For delicate electronics, work on a grounded surface and use ESD-safe practices when required. Match bit size precisely to the fastener to avoid rounding. If greater torque is needed, use the appropriate bit holder or a torque-limiting driver rather than forcing a precision bit.
