Powered Rolling Mill – TUI 130 Double Sided from Durston Tools. As with all Durston Tools powered mills, the TUI double sided 130 has variable speeds, as standard, in forward and reverse plus four sets of extension rollers securely stored behind black guards. The rolls themselves provide a dedicated flat rolling side, with a width of 130mm and a maximum roll thickness of 6mm, and a dedicated square groove wire rolling side, providing 19 grooves from 10mm to 1mm to create a perfect finish every time. The 1.1KW 110-volt motor offers consistent power through the lifetime of the mill. Digitally controlled variable speeds from 5 to 20 RPM means you have complete control over each roll and the side extensions provide for half rounds of 8, 6, 4, 3, 2, 1.5 mm for additional versatility.
