Screwdriver Bit Set Goobay Tools 77843 — Chromium-Vanadium Steel (Cr-V), 72 pieces

Goobay Tools 77843 is a 72-piece screwdriver bit set made from chromium-vanadium steel (Cr-V). The set includes a wide selection of standard magnetic bits and an adapter compatible with common cordless screwdrivers and powered bit holders. A quick-release bit holder and a compact, rubber-cornered storage case with stackable design make the set convenient for everyday repair, assembly and maintenance tasks.

Advantages

The set provides durable, corrosion-resistant Cr-V bits in a comprehensive range of profiles and sizes for versatile use. The magnetic, standardised bits fit most bit holders and cordless drivers, while the quick-release holder enables fast bit changes. The robust plastic case with rubberised feet protects surfaces, offers secure closure and can be stacked with other boxes from the series for neat storage.

Suitable for

• General DIY and household repairs
• Electronics assembly and maintenance
• Furniture assembly and flat-pack construction
• Automotive minor repairs and adjustments
• Mobile tool kits for tradespeople and hobbyists

When it may not be suitable

This bit set is intended for light to medium-duty screwing tasks. It is not designed for heavy industrial applications or continuous high-torque professional use where specifically hardened or specialised bits are required. For tasks requiring impact-rated or proprietary fastener profiles, choose dedicated tools matched to those requirements.

Key specifications

• Material: Chromium-vanadium steel (Cr-V)
• Number of pieces: 72 (bits and accessories included)
• Bit holder: 1 quick-release holder, 60 mm length
• Includes: magnetic standard bits, 1 socket adapter, 1 Y-bit
• Bit assortment: flat, Phillips (PH), Pozidriv (PZ), Torx (T, TH), hex (H), hex pin, spanner (U), spline, tri-wing, torque bits
• Case: compact plastic case with rubberised corners/feet and stackable shape

How to use

Select the required bit from the case and insert it into the quick-release bit holder until it locks. Attach the holder to a compatible screwdriver, cordless driver or the included socket adapter as needed. Use the magnetic bits to help retain screws during installation or removal. After use, return bits to their labelled positions in the case and close the lid to protect the tips and keep the set organised.

What to consider before purchase

• Intended use: suitable for light to medium-duty tasks rather than continuous heavy industrial use
• Compatibility: magnetic, standardised bits fit most bit holders and cordless screwdrivers, but check specific driver interfaces if needed
• Bit range: verify that the included profiles and sizes match the fasteners you commonly encounter

Usage recommendations

Use the quick-release holder for rapid bit changes during assembly work and keep the case closed when transporting to protect the Cr-V tips. For high-torque applications, use appropriate torque-limited tools and impact-rated bits.
