Thread: Miterfold-Router Blade - V-Blade

if you cant find em in USA what hope have you in dear ole Australia. We are a good mob down here but we dont produce miricles

Why not just use a 90 degree v groove router bit??

Tonto,
actually I saw a machine fabricated specifically for this purpose in a 2ndhand machinery place on the Gold Coast a few years ago.

Jurgen,
there's quite a few router bit manufacturers that make router bits suitable for this purpose. Alternatively, any good toolmaker/saw service could make or arrange to be made a suitable saw blade.

What in particular are you intending to mitre fold?

It is common to make cheap speaker boxes by mitre folding vinyl coated board.
there are some funky building materials that you mitre fold.

I visited a factory that built speaker boxes by this method they used a twin blade radial arm saw to cut the mitres. It was a scary looking thing with two blades at right angles.

you could use a 90deg v grrove bit as mentioned before but depending on what you intend to mirtre you may need to grind the tip off the point to widen the fold point.

there is an aluminium laminated board that you mitre fold, the supplier of the board sells a special 90 deg mitre bit with the correct flat ground off the tip to allow for the correct bending allowance.

does this help?

Thanks everyone
We want to fold MDF,mostly in to a 90.
But some other angles 22.5 and 45 are interesting as well.
The link will show you what we know so far, and what we try to find. Router bits usually have a statement not for miterfolding

The site you are linking is for a similar aluminium laminated product that I am familiar with under a diferent name.
However
Dont expect MDF to behave anything like that.
If you are wanting to mitre join MDF its best to cut it and glue it.
unless you are doing very shallow bends then you might get away with it.

cheers
