Bur Chuck
Free!
The Bur Chuck is the internal collet that holds a dental bur securely in the handpiece. Installing a fresh chuck restores grip, reduces wobble, and delivers smoother, more accurate cutting. Made from autoclavable stainless steel and sized to match common bur shanks, it’s a quick, cost-effective way to revive handpiece performance. Ideal for clinics and labs that value reliable torque transfer, clean seating, and consistent results.
Description
A Bur Chuck is the precision clamping collet inside a dental handpiece that grips the bur shank during rotation. When the chuck is in good condition it centers the bur, transfers torque efficiently, and keeps cutting smooth with less vibration. Replacing a worn chuck restores grip and improves the accuracy and feel of your handpiece. This model is manufactured from corrosion-resistant stainless steel with a slotted sleeve design for reliable, repeatable clamping and easy maintenance.
Key features and benefits:
-
Secure, concentric grip that reduces bur wobble and chatter.
-
Durable stainless steel construction, fully autoclavable.
-
Smooth insertion and release when used with the matching handpiece mechanism.
-
Restores cutting performance and extends the service life of the handpiece.
-
Available to fit common shank standards (for example FG 1.6 mm or RA/HP 2.35 mm, depending on model).
-
Simple to replace during routine handpiece servicing.
Typical uses:
-
Routine replacement when burs slip, won’t seat fully, or show run-out.
-
Preventive maintenance programs in clinics, laboratories, and teaching facilities.
-
Optimizing finishing and crown-prep accuracy where concentricity matters.
How it compares:
-
Versus continuing with a worn chuck, a new chuck improves safety and cutting efficiency immediately.
-
Push-button and wrench-type handpieces use different release mechanisms; the chuck is the inner component that actually holds the bur.
Care:
-
Follow handpiece servicing protocols: clean, lubricate if specified, and sterilize between patients. Inspect for wear or debris in the slots to maintain consistent grip.
