Mandrel Tube Bender

Designed to bend aluminium, steel, stainless steel and copper tubing in the following sizes:

• 3/8" dia. x 16 swg (0.065" wall) on a 1.0" centre line radius
• 1/2" dia. x 16 swg(0.065" wall) on a 1.0" or 1.5" centre line radius
• 5/8" dia. x 16 swg (0.065" wall) on a 1.25" or 1.5" centre line radius
• 3/4" dia. x 16 swg (0.065" wall) on a 1.5" or 2.0" centre line radius

• 7/8" dia. x 16 swg (0.065" wall) on a 2.0" centre line radius
• 1.0" dia. x 16 swg (0.065" wall) on a 2.0" centre line radius
• 1.25" dia. x 16 swg (0.065" wall) on a 2.5" centre line radius
• 1.375" dia. x 16 swg (0.065" wall) on a 2.5" centre line radius

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 which means we can now easily bend 1.0” x 16swg stainless steel tubing on a 2.0” centre line radius.

This machine retains all the standard features of the Mk 1-2 and 3 machines and is the most versatile machine in the range being able to bend pipes ranging in size 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.

The machines are extremely easy to use and allow for multiple bends in the same piece of tube at alternate angles on different planes. Once the machines are set for a particular size of tube it will be found that multiple bends are rapidly achieved.

Check out the sample pictures of the 5/8" and 3/4" od tubing bent on a 1.5" CLR, and the 1.0" steel and stainless steel tube bent on a 2.0" CLR.
