Double Up For More Power! This is the offset fine and course tooth combination mounting the fine tooth Lancelot first with the course tooth Squire on top. When holding the grinder with the blades at between 25 to 30 degrees to the material, you have 34 teeth sweeping or raking material away sideways or in downward strokes. Will also remove material in slice, plunge and straight cuts but leaves a step or bench shape with each pass. Best used for convex shaping in larger works. Rapidly removes material but leaves a course finish. Also great used individually for detail work.
