Hi guys, I was wondering how to make a radial bend without using a special tool to do so? Thanks in advance

Lay the PE flat on your cutting mat (or similar) and then use drill bits to "Roll" the PE. Start with a larger bit and then use progressively smaller bits until you get to the radius you need.

Hope this helps

Depending on the size of the part and how tight the radius needs to be, annealing the PE and using a surface with some "give" in it might also help.







These small tool clamp straps are being rolled on wide rubber bands (a soft surface) with a piece of steel tubing. They're thin enough that they don't need to be annealed, but the same idea works for larger pieces.

Often the most difficult part of the bending job is finding the right expedient tools.

HTH,

A drill index will give you an amazing array of bending tools- in the drill shanks themselves.
