Steelman 18240 Carbide Burr for Tire Repair

The Steelman 18240 is a 1/8-inch carbide double cut burr built for the cleaning step of pneumatic tire repair. It prepares a uniform channel through rubber and steel belts for plug stems or patch units. Professional technicians and serious DIY users handling puncture repairs will find it matches the RMA procedure requirements.

Fits SLP9213 Adapter for Low Speed Buffers

Installation requires the Steelman SLP9213 3/8-inch adapter and a low speed tire buffer tool. The burr shaft includes flats so the adapter set screw grips securely, preventing the tool from seizing inside the tire material during operation. Using high speed rotary tools instead of a low speed buffer creates friction scorching that weakens the tire structure.

1/8-Inch Channel Width for Standard Plug Stems

The double cut geometry removes material on both insertion and withdrawal strokes, speeding up the cleaning pass. It comfortably produces a clean, smooth 1/8-inch wide repair channel suited to common plug stem dimensions. The carbide steel construction resists wear when cutting through embedded steel belts, though the fixed diameter cannot accommodate larger injury sizes.

Questions about this item

How do I confirm the 18240 burr is cutting a clean, uniform channel in the tire injury?

Run the low-speed buffer through the puncture; the double-cut carbide flutes should remove rubber and steel belts smoothly on both insertion and withdrawal without friction scorching, leaving a consistent 1/8-inch wide channel ready for a plug stem or patch.

What comes with the 18240 and what must I source separately?

The package contains only the 1/8-inch carbide double-cut burr; you must purchase the STEELMAN SLP9213 3/8-inch adapter separately and fit the assembly to your own low-speed tire buffer tool.

Which version of this burr should I choose for standard RMA tire-repair procedure?

The 18240 is the single 1/8-inch carbide double-cut model referenced in the Rubber Manufacturer's Association repair step; no other diameter or cut-style variants are offered under this part number.
