I might be blind Jazz but they don't seem to sell the heavy duty version, prices are very good. I recovered the aluminium extrusion from a magazine printer and KJN charged me 75p a cut and £1 a hole so at least for me was lucky to have KJN on my door step. I had 3.6m lengths to deal with lol it was all the heavy duty profile.

I watched them cut mine so maybe them spent more time on it lol because it was spot on, I'm sure they have a DRO on the saw but was couple of years ago and they have multiple saws so maybe not all have the DRO.

The drilling is a cnc drilled so shouldn't be any issue there.

If that other firm sell heavy duty version I certainly use them next time if I don't buy another magazine printer to scrap.
