ITC Gets a Hold on Precision Boring With New Toolholders

ITC Gets a Hold on Precision Boring With New Toolholders

To correspond with the launch of its extensive line of Micro 100 boring and internal turning tools, Industrial Tooling Corporation (ITC) has now launched the new range of QTH and QTHM toolholders.
 
The MicroQuik line of solid carbide boring, threading, grooving and profiling tools has rapidly established a reputation for its impervious tool life, innovative geometries and machining performance. Now, the established series of cutting tools for turning centres, sliding head lathes and machining centres has been provided a productivity boost with the introduction of the 3-point locating and locking toolholder line.
 
The QTH and QTHM toolholders have a unique 3-point locate and lock design that guarantees centreline repeatability of +/-0.1mm when changing from one solid carbide tool shank to the next. The system works with a rotating locking screw that pushes the tool insert downwards and back against a locating pin to deliver unparalleled rigidity, repeatability and tool life. This allows solid carbide boring, threading, grooving and profiling tools to be interchanged within 30 seconds, a tool changeover time that will drastically cut machine downtime and improve set-up procedures.
 
The new toolholders are precision ground for a concentricity of less than +/-0.01mm and are heat treated to extend their tool life. In addition, the holders have a through hole and adaptor for through-coolant machine tools. The QTH series are imperial dimension holders with shank diameters of 0.5, 0.625, 0.75, 1 and 1.25 inch and an overall length of 2.750 inch. The internal diameter for clamping the carbide tool shank varies from 0.1875 to 0.5inch whilst an extended length version is available with an overall toolholder length of 5.8 inch.
 
For metric machine shops, the QTHM line of toolholders is available with a diverse range of dimensions to suit all machine types. The QTHM series is available in all standard sizes that include 12, 16, 20, 22, 25 and 32mm shanks. This diverse range of shank diameters makes the QTHM and the QTH ideal for installation on sliding head turning centres with small toolholder capacity and platen availability. In addition, the quick change configuration of these toolholders really comes into its own on small machines that make access to the tool platen and the respective changeover process difficult. Simultaneously, with 25 and 32mm shank options available, the MicroQuik toolholders can easily be applied to larger more robust turning centres.
