Operating Instructions
General Use
The Wera Impaktor bits are specifically designed for use with impact drivers, offering enhanced durability and resistance to extreme loads. Follow these guidelines for optimal performance:
- Always select the correct bit type and size for the fastener to prevent damage to the fastener head and the bit.
- Apply firm, consistent pressure to the tool to keep the bit engaged with the fastener.
- Avoid excessive angling of the tool, which can lead to cam-out and premature wear.

Impaktor Technology
The Impaktor technology utilizes a combination of material properties and geometric design, including a torsion zone, to absorb peak loads and extend the bit's lifespan, especially in impact applications. This significantly reduces the risk of premature bit breakage.

Maintenance
Cleaning
After use, wipe down bits and the holder with a clean, dry cloth to remove dirt, dust, and debris. Avoid using harsh chemicals or abrasive materials that could damage the bits or case.
Storage
Store the Bit-Check set in a dry environment to prevent corrosion. The robust Bit-Check case provides excellent protection and organization for the bits, ensuring they are readily available for your next task.
Inspection
Regularly inspect bits for signs of wear, such as rounded edges, chipped tips, or cracks. Replace worn or damaged bits immediately to ensure optimal performance, prevent damage to fasteners, and maintain safety.
Troubleshooting
Bit Slipping / Cam-out
- Ensure the correct bit size and type is used for the fastener.
- Apply more consistent downward pressure on the tool to keep the bit engaged.
- Check if the bit is worn; replace if necessary.
Bit Breakage
- While Impaktor bits are highly durable, extreme misuse or incorrect application can still cause breakage. Ensure proper technique and bit selection.
- Verify that the bit is fully seated in the holder and the holder is correctly inserted into the tool.
