How do you fix a bur stuck in a high speed handpiece?

If a bur is stuck in a high speed handpiece, the best solution is to release the chuck mechanism gently, apply bur release spray if available, and rotate the shaft slightly to loosen the rotary cutting device. Regular high speed handpiece maintenance prevents future jams and ensures smooth operation.

⏱ 7 min read. If you’ve ever had a bur stuck in high speed handpiece mid-procedure, you know the frustration and stress it can cause. Patients wait, time ticks away, and your workflow halts. The good news? With proper high speed handpiece maintenance and a few proven tricks, you can free the bur in minutes, prevent costly downtime, and extend the life of your equipment.

Why Does a Bur Get Stuck in a High Speed Handpiece?

A bur stuck in high speed handpiece usually happens due to debris, worn chuck springs, improper insertion, or lack of lubrication. Since a rotary cutting device used on a high speed handpiece spins at over 300,000 rpm, even small blockages can lock the mechanism.

Quick Solutions to Remove a Stuck Bur

Here are step-by-step techniques to release a jammed bur safely:

1. Disconnect the handpiece from the tubing to prevent accidental rotation.
2. Press the chuck release button while gently twisting the bur.
3. If still stuck, apply a dedicated bur release spray or lubricant around the chuck.
4. Rotate the handpiece head slightly to relieve pressure.
5. Use a bur removal tool if available, never pliers — which can damage the turbine.

High Speed Handpiece Maintenance Tips

To avoid future bur jams, follow these essential high speed handpiece maintenance practices:

• Clean the chuck with specialized brushes daily.
• Lubricate before every sterilization cycle.
• Use only compatible burs with the correct shank length.
• Inspect for wear and replace turbines before failure.

When to Consider High Speed Dental Handpiece Repair

Sometimes, at-home fixes aren’t enough. You should consider professional high speed dental handpiece repair if:

• The chuck no longer grips burs properly.
• You hear unusual sounds or vibration when in use.
• Lubrication and cleaning don’t solve sticking issues.
• Turbine power is noticeably reduced.

Choosing the Right Rotary Cutting Device

Not all burs are created equal. The rotary cutting device used on a high speed handpiece directly impacts performance. Diamond and carbide burs each serve specific purposes — from fine enamel shaping to heavy-duty cutting. Choosing the right bur reduces stress on the chuck and prevents sticking.

For maximum reliability, pair your maintenance routine with trusted tools like the KentDO LED Dental Handpiece High Speed Triple Spray, designed to minimize bur slippage and extend handpiece life.
