MK 4 Bender (3-1)

Because of the sheer physical effort involved in bending 1.0" x 16 swg stainless steel we designed a new machine that we call the 3-1. This machine has a three to one reduction ratio between the operating spindle and the main mandrel spindle. Initially we used gears, but found that a duplex morse chain gave much better results.

Net result is that with this MK 4 Bender, we can easily bend 1.0" x 16 swg stainless on a 2.0" centre line radius.

This machine retains all the standard features of the Mk 1-2 and 3 machines. It is the most versatile machine in the range being able to bend pipes ranging from 3/8" diameter all the way up to 1.0" in stainless steel, and 1.375" in aluminium and copper.

In all cases, a thinner wall tube can be bent very satisfactorily and we can provide internal 'bullet'-type mandrels to suit your tube wall thickness requirements.

Due to the unique design, the Useful Tools Tube Benders will allow amazingly tight bends to be formed with the minimum of tube distortion (a nominal 3-4%).

The Tube Benders come with an easy-to-read degree dial to allow precise angles of bend to be achieved and repeated.

Alternate sized mandrels are supplied with back plates, clamp plates, and internal 'bullets' for 16 swg tubing.

We would be very happy to provide non-standard and metric mandrels on request.
