PSO regrooving blade | Tread regrooving | Pack of 20
The R4 oval blade extends PSO's oval blade line beyond the R3, covering grooves from 9 to 16 mm wide. It's the widest oval blade available, built for the deepest, most demanding tread grooves found on industrial tyres.
Construction and Materials
The blade is made from high-strength material, which keeps it working well over extended use. It fits into the heating head of the regrooving tool - the head itself only heats up once pressed against the rubber, with current running through the blade to generate the heat.

Application
This blade regrooves tread on tyres designed for it, marked REGROVABLE, as well as thick-tread tyres such as those used on agricultural machinery and trucks. Its 9-16 mm cut width suits grooves too wide for the smaller oval blades in this line, most often found on industrial and oversized tyres. It fits into the heating head of the regrooving tool; keeping the blade clean helps maintain cutting precision.
