I have 3 of the GB Titanium bars. The true made in Australia bars, not made in China as some of their lower cost bars. So far I’ve been impressed with their minimal wear. The bar, not the paint, as stated above (the orange is a nice color through).
Marketing said rails are infused (not coated) with titanium boron nitride in a furnace, supposedly improves rail hardness, similar to cryo dipping.
I also like the 6-pin roller nose- I heard complaints that the tsumura 4-pin roller nose didn’t stand up to extended abuse such as bore cutting, and the 5-pin of Sugihara lasts longer. So far I haven’t had any issue with my 6-pin roller noses. Although the nose is replaceable, GB manufacturing seems to be up in smoke, so I’m a little leery about IF I need a replacement nose in the future if I’ll be able to find one.
The price was great on the ones I’ve bought, they seem to be an under the radar brand. The worst part is that they are no longer made, so finding them is impossible. Oh, and they weigh a *f-word ton. I mean, they ain’t no laminate or lightweight / reduced weight bar.
