Can anyone comment on the longevity of these bits (the replacement blades, that is).

I have been contemplating buying a complete CNC signmaking set by Amana, either the 8 piece set (here) or the 18 piece set (here). The 8 piece set is more palatable (from a hobbyist perspective), but I really am lusting over the 18 piece set (over $500!!!).

I have spent entirely too much time looking for "standard" router bits to do my CNC work, and I am very tempted to pull the trigger on one of these sets (the 18 piece set would be my Xmas present... and next 3 Father's Day and birthday presents ;) ).
I bought a specialty 60 degree v-bit from Lee Valley (here) that was $45, and as nice as it cut, somehow I managed to knock about 2 mm off of the tip, so that is $45 down the toilet. I know I can buy cheaper (i.e Chinese made) bits online, but I would prefer something that does the job for a decent price and won't let me down when I need it most.

One of the bits that may prove to be of value to most people is this one: In-Grooveâ„¢ Insert Engraving System Sets.

On a related note, does anyone know of Canadian sellers of the Amana line? I saw that Richelieu carries them, but I think they don't have a normal storefront (distributor only). I am a little afraid to see what the final cost (after exchange, duty, shipping, etc) would be if I ordered it direct.

For the money ~$4 a replacement insert they are great. I used one corner today to cut about 20 signs. The signs are cut in cypress and the letters are 3" inches tall and vary in length from 8-20 letters plus a simple logo. I use this bit exclusively for all my 90 degree v cuts and love it. I still reccoment it highly!

Is it difficult to align the blade in the bit? I'm worried that if the point is not in the center it won't cut well.

Ugh, so many things I have remade because of that. But the error rate is going down and that's all I can ask for.

On mine, the insert wants to sit in the correct position. I put it in with the screw loose. I then wiggle it around a little and the insert settles into place. Then I slowly tighten the set screw. The key I have found is to not force the insert too far over to the cutting side.

Thanks for the review. I may order this bit also: http://www.toolstoday.com/p-5785-insert ... r-bit.aspx

Both use the same replacement blades. Anyone have experience with this surfacing bit?
