THINBIT, manufactured by Kaiser Tool Co., announces the expansion of its GROOVE ’N TURN line of dovetail grooving inserts. Dovetail grooving inserts are used to machine O-ring dovetail grooves with 66° undercut angles. The insert design is optimized for strength by utilizing an insert pair to generate the groove form. Insert sizes are .030”, .050, .060, .070”, .080, .090”, .100”, .125” and .150” with major diameters starting at .300”.
Available in submicron-grain carbide grades for ferrous and nonferrous materials either uncoated or with TiN, TiCN, TiAIN or diamond film coatings. GROOVE ’N TURN dovetail inserts can be used on conventional, Swiss and CNC machines.
Toolholders are available in square shank size 5/16” through 1-1/4” and round shank sizes ½” through 1” with straight and 90° presentations. GROOVE ’N TURN dovetail inserts fit existing “L” series THINBIT toolholders.

In numerical-control applications, a cut shorter than the programmed cut resulting after a command change in direction. Also a condition in generated gear teeth when any part of the fillet curve lies inside of a line drawn tangent to the working profile at its point of juncture with the fillet. Undercut may be deliberately introduced to facilitate finishing operations, as in preshaving.
