4.5 mm Tire Repair Carbide Bits, Tire Repair Reamer Carbide Files
The 4.5 mm standard: sized for the most common repair plug, with the red grip cap shops recognise instantly.
Design and Construction
A 4.5 mm carbide reamer with the standard red grip cap – the diameter that matches the most common puncture-repair plug. Carbide cutting teeth on a tough steel core handle rubber plus steel-belt layers.
How It Works
At 1,000-3,000 RPM the reamer cleans and sizes the puncture channel so the plug seats airtight; the carbide teeth stay sharp through dozens of repairs.
Applications
Tyre shops, roadside repair kits, truck and car tyre services.
Field Cases
- Tyre shop: one 4.5 mm reamer serviced a week of punctures before replacement.
- Roadside kit: the red cap made the right tool findable in the dark.
- Truck service: steel-belt punctures reamed clean in seconds.
