Please bear in mind that for this model planer you may need the relevant conversion kit if you do not already have it. Pack of 10 pieces of 82.55mm long, reversible, solid tungsten carbide, planer blades. These blades are manufactured in FINE GRAIN tungsten carbide, and are ground to a mirror quality finish to produce the sharpest, keenest edges possible - far keener than standard blades that are available elsewhere.
