Here we have for sale planer/thicknesser HSS blade conversion - reversible blades (a pair).

This item is from a Wadkin OUS. Will work any 18" planer/thicknesser that uses HSS cutters.
The backing plate makes up the 4mm gap along with the 2mm blades.
We have two pairs available, so apologies to anyone with three blades in cutter block. This is for TWO blades only.

Any questions please email.
