Low-Speed Carbide Burr 3mm – for Tire Puncture Repair
Mechanical burr for repair hole preparation | Max speed: up to 1200 RPM | Sold per piece
The 3mm low-speed burr is used to work the damaged rubber before the actual tire repair. Its notched, sharp edges quickly and precisely clean the puncture opening, giving the hole the shape and smoothness needed for a proper fit of a repair insert or plug. The burr runs at up to 1200 RPM and can be mounted in a low-speed grinder, a drill chuck, or a quick-release chuck — the latter requires an additional quick-release adapter for burrs.
Product Description – Low-Speed Burr 14-340-1
The burr is precision-made from high-quality metal. The notched, sharp edges of the working section quickly remove material from the walls of the puncture channel, allowing fast and accurate reaming of the repair hole. A surface prepared this way allows for a more effective repair and a better bond between the insert or plug and the tire.

Frequently Asked Questions
Why is reaming the hole with a burr so important before repair?
An unprepared or unevenly cut hole can lead to further damage in the repair area or a cracked repair insert after installation. The burr precisely cleans the puncture channel, allowing a tighter, more durable bond between the insert or plug and the tire.
What's the recommended operating speed for this burr?
The burr is a low-speed tool designed to run at up to 1200 RPM. Check that the tool driving it doesn't exceed this value before use.
Which tools does the 14-340-1 work with?
The burr can be mounted in a low-speed grinder, a drill chuck, or a quick-release chuck. For a quick-release chuck, an additional quick-release adapter for burrs is required.
Is the quick-release adapter included with the burr?
No — the quick-release adapter for burrs needs to be purchased separately if the burr is going to be mounted in a quick-release chuck.
