Usage Guidelines

RECOMMENDED
SAFE USE FOR CARBIDE BURRS

Follow these guidelines to maximize product performance, safety and service life.

Select Correct Speed
Always choose the appropriate rotational speed for the material being machined before starting the grinder.
Match Burr to Material
Choose the appropriate burr shape, diameter and cut type for the specific material being processed.
Secure Shank Connection
Confirm that the burr shank and chuck of the die grinder are firmly connected before operation.
Avoid Excessive Pressure
Do not apply too much pressure during grinding. Excessive heat shortens burr lifespan significantly.
No Combustible Environments
Never use carbide burrs in environments containing combustible gas or flammable materials.
Wear Protective Equipment
Always wear safety glasses and protective gloves before grinding. Personal protection is mandatory.
