A pack of 1 x Tungsten Carbide 30mm replacement blade for all RALI G30, G03 and B30 Hand Planes. Carbide is best suited for hard woods, and will have excellent longevity on both soft and hard wood. For abrasive timber and sythetic materials. Each blade is double-sided and can be rotated when one side is dull. These blades only fit in RALI G30, G03 and B30 models where they index into the blade holder and do not need to be adjusted in any way. Put the blade in and you can plane immediately. Blade replacements take seconds. The edges of each blade are rounded slightly so as to not leave marks in the wood.
