Operating Instructions
The Wera Impaktor bits are specifically engineered for use with impact drivers, providing superior performance and durability. Always ensure the bit is correctly seated in the holder and the holder in the power tool before operation.
Using Impaktor Technology:
- High Stress Applications: These bits are designed to withstand the high torque and impact forces generated by impact drivers, reducing the risk of premature wear or breakage.
- Diamond Coating: Some Impaktor bits feature a diamond coating that bites into the screw head, reducing cam-out and improving grip, especially useful for stubborn screws.
- Torsion Zone: The unique torsion zone in the bit absorbs peak torque loads, extending the bit's lifespan.
- Magnetic Ring Holder: The Impaktor holder includes a magnetic ring that securely holds screws, facilitating one-handed operation and preventing screws from dropping.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your Wera BIT-Check 30 Impaktor bits.
- Cleaning: After use, wipe bits clean of any debris, dust, or grease. A dry cloth is usually sufficient. Avoid harsh chemicals that could damage coatings.
- Storage: Always store the bits in their original Bit-Check case. This protects them from corrosion, loss, and damage. Keep the case in a dry environment.
- Inspection: Periodically inspect bits for signs of wear, such as rounded edges or cracks. Replace worn bits to prevent damage to fasteners and ensure safe operation.
- Bit Holder Care: Ensure the Impaktor bit holder is also kept clean. The magnetic ring should be free of metallic debris to maintain its effectiveness.
Troubleshooting
While Wera Impaktor bits are designed for durability, certain issues can arise. Here are some common problems and their solutions:
- Bit Stripping Screw Head:
- Ensure you are using the correct bit type and size for the screw head.
- Apply firm, consistent pressure to keep the bit engaged with the screw.
- Check if the bit is worn; replace if necessary.
- The diamond coating on Impaktor bits is designed to reduce cam-out, but proper technique is still crucial.
- Bit Breaking:
- While Impaktor bits are highly robust, excessive force or improper angle can still cause breakage.
- Ensure the bit is fully seated in the holder and the holder in the driver.
- Avoid using bits that show signs of damage or fatigue.
- Screw Not Holding to Magnetic Holder:
- Check if the magnetic ring is clean and free of metallic shavings or debris.
- Ensure the screw is made of a ferromagnetic material that can be attracted by a magnet.
