Custom tooth configurations available for special applications.
Q: What makes SD shape different from other burr shapes?
A: The tapered design with rounded end provides better access to angled surfaces and produces smoother transitions in contouring applications.
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 angles for specialized applications?
A: Yes, we can manufacture custom taper angles from 10° to 45° to meet specific requirements.
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.
