Frequently Asked Questions
1. What is a BT Dual-Contact Face Mill Holder?
A BT Dual-Contact Holder provides contact at both the taper and face of the spindle, offering improved rigidity and accuracy. This design helps maintain tool stability during high-performance milling.
2. Why are dual-contact BT holders used?
They reduce tool deflection, improve cutting finish, and provide higher precision, making them ideal for aerospace, automotive, and mold industries that require tight tolerances.
3. Are these holders compatible with standard BT machines?
No, they are made for BT machines with dual-contact spindle systems. Using them on regular BT spindles will not provide proper contact.
4. Are BT Dual-Contact holders suitable for high-speed machining?
Yes, they are fully balanced for stable high-speed operations. Their increased rigidity provides better performance under heavy cutting loads.
5. How do I care for these holders?
Clean both the taper and face contact surfaces after each use. Dirt or scratches can affect the dual-contact fit and reduce machining accuracy.
6. Do they require special pull studs?
Yes, dual-contact holders need specific pull studs designed to maintain proper face contact for maximum rigidity.
