Fixing a flat? This professional-grade carbide cutter makes tire repair way easier. It's designed to clean out the puncture hole and remove damaged steel belts before you insert a mushroom plug or patch. The solid carbide construction is super hard, wear-resistant, and stays sharp for multiple uses. It comes with three shank diameters (3mm, 4.5mm, and 6mm) to fit different low-speed pneumatic drills or hand tools. The triangular cutting surface gives a good grip and prevents slipping, and the fish-scale edges cut cleanly. If you do your own tire repairs at home, in the garage, or on the go, this durable bit is a smart addition to your toolkit. Makes the job faster, cleaner, and more reliable.
