Frequently Asked Questions (FAQs)

1. What does a boring bar do?

A boring bar is used in the cutting of an inner suface. It can make the hole, which has a big diameter, which is needed an accurate diameter, and which is needed a high surface roughness.

2. What are boring bars made of?

A boring bar is usually made from tool steel, heavy metal or carbide. Each type's vibration resistance depends on its modulus of elasticity. The greater the modulus of elasticity, the greater the cutting force needed to bend, or deflect, the material.

3. How do I choose a boring bar?

When choosing a boring bar, look at the diameter and length of the hole to be bored. Then choose the proper boring bar based on the diameter to length ratio that will work best for the application.

4. How do anti vibration boring bars work?

Advanced Damping Technology Silent Tools fight vibration with a damping unit inside the bar. When cutting forces cause the bar to vibrate, the damping mechanism, which consists of a heavy mass supported on rubber spring elements, starts to vibrate. Oil inside the unit increases the damping effect.
