Purpose-Built Tire Repair Tool

The Steelman 18240A carbide double-cut burr is engineered for the critical cleaning step in pneumatic tire repair procedures. It prepares a uniform channel through rubber and steel belts for plug stems or patch installations. Professional technicians and DIY mechanics use it with a low-speed tire buffer to achieve consistent results without damaging the tire structure.

Low-Speed Operation Prevents Heat Damage

The burr mounts securely in the included adapter via a 2mm hex set screw that engages shaft flats for positive retention. This assembly fits a 3/8-inch quick-change chuck on a low-speed buffer, eliminating the friction scorching that can weaken tire casings. Double-cut geometry removes material on both insertion and withdrawal strokes, reducing the time the tool spends in contact with the repair area.

Adapter Extends Tool Compatibility

The supplied adapter converts the 1/8-inch burr shank for use with standard 3/8-inch quick-change chucks found on common tire buffers. This allows the carbide cutter to be swapped quickly without dedicated collets or proprietary hardware. The 90-day manufacturer coverage applies to the complete assembly.

Questions about this item

How do I fit the carbide burr into the adapter before using it on a low-speed tire buffer?

Align the flats on the burr shaft with the 2 mm hex set screw inside the adapter, then tighten the screw so the burr cannot be seized by tire material and stop turning.

What part of this kit will need replacement after repeated tire repairs?

The carbide double-cut burr itself wears down and will need to be swapped out; the adapter and set screw remain reusable.

What limits continuous use on steel-belted tires without damaging the tire?

Friction scorching is the first risk; the tool is designed for low-speed buffers to create a clean, uniform channel without overheating the rubber.
