The benefits of the Shaper Duo series over commonly used broaching tools include improved cycle times, reduced tooling costs and the flexibility to produce a complete range of hexagon sizes with a single tool. Shaper Duo in hexalobular form is offered as a single-sided tool with an optimised length of 70 mm and a 5 mm shank diameter. A multitude of geometry options are available for manufacturing hexalobular socket sizes, including T6, T7, T8, T10, T15, T20, T25, T27 and T30.
For the provision of hexagonal socket forms, NTK’s Shaper Duo is manufactured as a double-sided tool with diameters that include 2, 3, 4, 5, 6 and 8 mm, and overall length options of 50, 60, 70 and 80 mm. The dimensions of the 120° point-angle tool support the production of hexagonal heads with an across-flat (AF) base of 1.5, 2, 3, 4, 5, 6 and 8 mm. These seven AF base dimensions enable the end user to machine hexagonal forms from 1.4 to 12.2 mm AF.
Completing the Shaper Duo line is the double-sided square-socket Shaper Duo insert. Like the hexagonal variant, the 90° geometry square-end tool is manufactured in overall lengths of 50, 60, 70 and 80 mm, with cutting depth up to 16 mm. Featuring a tool shank diameter and corresponding base AF dimension of 2, 2.5, 3, 3.5, 4, 5, 6 and 8 mm, the square socket Shaper Duo can manufacture precision square socket forms from 1.9 to 8.1 mm.
