Frequently Asked Questions

AI
Steel blocks offer superior durability and thermal stability for high-precision calibration, while aluminum blocks are lighter and cheaper, making them ideal for quick setup and rough measurement tasks in woodworking.
For professional metrology or industrial calibration, a certified Grade AS or Grade B set with a certificate is essential. For general woodworking setups, uncertified aluminum blocks are usually sufficient and more cost-effective.
Store them in their original cases to prevent dust and moisture damage. Always handle steel blocks with gloves to avoid transferring oils from your skin, which can cause corrosion and affect measurement precision over time.
