Chuck
A replacement chuck for a laboratory handpiece or grinder, gripping the bur shank and holding it concentric. A true-running chuck is what keeps a bur cutting cleanly instead of chattering.

Key Benefits
- A true-running chuck is what keeps a bur cutting cleanly instead of chattering.
- Brushes and armatures listed separately for Marathon and for Strong, in 35K and 45K versions.
- Brushless and brush micromotors, 35K and 45K handpieces, and the carbon brushes, armatures, chucks and bearings that keep them turning.
Problems It Solves
- Burs that slip under load
- Chatter marks on finished surfaces
- A handpiece retired because it no longer grips
Who It Is For
- Service technicians
- Laboratories noticing bur runout
- Dealers supplying handpiece spares
How It Compares
Cheaper than a new handpiece and usually the only worn part when grip has been lost but the bearings are still quiet.
Use Guide
Open the chuck fully before inserting a bur and never run the handpiece with the chuck empty and closed.
