Expert Q&A
Q: How do I select the right tooth configuration?
A: Consider your material hardness and desired finish. Our engineers can recommend optimal configurations based on your specific application.
Q: What's the maximum RPM for these burrs?
A: Standard rating is 35,000 RPM. Carbide-shank versions can operate at 50,000 RPM with proper cooling.
Q: Do you offer custom marking/labeling?
A: Yes, we provide laser engraving for part numbers, logos, or other identification marks.
Q: What's your lead time for custom orders?
A: Standard configurations ship in 3-5 days. Custom tools require 10-15 days for production.
Q: How do your burrs compare to competitors?
A: Our proprietary carbide formulation and grinding process deliver 20-30% longer tool life than industry averages.
