Thinbit, manufactured by Kaiser Tool Company, has expanded its Groove ‘N Turn line to include dovetail grooving inserts. Dovetail grooving inserts are used to machine O-ring dovetail grooves with 66-degree undercut angles. The insert design is optimized for strength by utilizing a left/OD and right/ID insert pair to generate the groove form. Insert sizes are 0.030", 0.070", 0.090", 0.100", 0.125" and 0.150", with major diameters starting at 0.300". The inserts are available in sub-micron grain carbide grades for ferrous and nonferrous materials either uncoated or with TiN, TiCN, TiAIN or diamond film coatings. The dovetail inserts can be used on conventional, Swiss and CNC machines.
Toolholders are available in square shank size ranging from 0.3125" to 1.25" and round shank sizes ranging from 0.5" to 1" with straight and 90-degree presentations. The dovetail inserts fit existing “L” series toolholders.
