The extension to the range of Stick Duo double ended solid carbide boring bars is said to improve surface finish, tool life and productivity for the small parts turning shop. By blasting high pressure coolant directly through the tool to the cutting edge, customers will immediately realise a number of benefits.

The new Stick Duo Splash is available with a number of options that include an SBFS type carbide bar for boring, the SBFB type for profiling and the SBG type for internal grooving operations. The SBFS type is suitable for bores and holes from 2 to 8mm diameter with boring bar diameters increasing in 1mm increments. Incorporating an ultra sharp cutting edge with a 5° clearance and rake angle, the SBFS is available with an overall length of 50, 60, 70 or 80mm to suit the machining depth demands of the customer.

The SBFB boring bar for profiling incorporates NTK’s F Style chipbreaker that discharges chips away from the cutting area to demonstrate a high degree of chip control and evacuation. It has been developed for profiling small bores from 2 to 6mm diameters and includes a corner radius of either 0.05 or 0.15mm to extend tool life and prevent edge breakages.

The internal SGB type grooving bar is available for bore diameters from 3 to 8mm with a groove width  of 0.5, 0.75, 1, 1.5 and 2mm. The clearance between the boring bar and the cutting edge allows a grooving depth of 0.8, 1, 1.2, 1.8 or 2.2mm depending upon the groove width selected by the customer. As with the two other styles, the SGB can be provided with overall bar lengths from 50 to 80mm and with  corner radii of 0.05mm to prolong tool life and deliver consistent machining performance.
