General description A two flute cutter with an extra long shank, designed for deep grooving, rebating, and mortising. It is particularly useful for template work when the thickness of the template restricts depth. Extra care must be taken to avoid breakage; it is recommended to take more passes than usual and only cut up to half the diameter of the cutter in one pass, especially for cutters under 3/8 inch diameter. Technical specifications Cutter diameter (D): 6.3 mm Cutting length (C): 19 mm Shank size: 1/4 in
