T660 Dual T Square with Viperbite™


( / )

Please select all options.


With our innovative ViperBite™ Gripping System, the 660mm long T660 Dual is an incredibly well designed and impressively built British T-Square. The key difference to the T660 is that the Dual version headstock can be mounted at either side or 100mm down the ruler to create an overhand for use as a circular saw or jigsaw guide. Quickly draw straight and precise parallel and square lines with ease. 

CNC machined from 10mm and 6mm T6 6082 aluminium extrusion with an 18 micron thick anodised surface, it really is unashamedly over-engineered. 

The T660 Dual measures 660mm from the inside of the headstock and includes scribe holes every 150mm, with an extra scribe at 610mm for halving boards that measure 1220mm. 

The ViperBite Gripping System is a simple but effective method to prevent accidental lateral movement when scoring or marking along the edge of the T-Square. Ordinary woodworking screws can be used to 'bite' into the surface of boards such as plywood, MDF, OSB, foam board or plasterboard.

Theres a handy cam tab to prevent the headstock from rotating off the edge of the workpiece.
