Engraving bits...

[Boyan Silyavski]

IMHO best all around bit for engraving is 60 degree, i prefer it on 1/4 shank.

The 90 degree are good for cuts for folding say Dibond or other materials. Not very useful on signs.

The 30 degree are best for jewelry and most of all for small stamps and very small signs. This is a very needed bit, but its very breakable. Any small mistake and snap..., not good for wood though and easily melting plastics.

Yes 3mm shank, so it seems they are not that useful after all.

Need to look for some 60degree 1/4 shank ones?

Horses for courses, what you want to engrave will determine the angle, OD and tip size,

Good point - no idea at present ;)

I guess in future, aluminium, plastics, brass.

What sort is best to look out for?

But 30 degree bits are usefull, it does not matter that they are 3mm. I would say even better, because it's one thing to brake a 3 euro 1/8 bit and another 15euro 1/4.

That's my all time favourite 60 degrees, 1/4 bit. solid carbide, Kyocera and only 5 euro, ebay item 151942760125. No to speak of that it could be sharpened 100 times if you have a grinder, i pay to a guy here locally 2 euro each time to grind it fresh. When i am lazy i use it for final slot cut, instead of changing bits

I'm really careful with my Nine9 engraving tool inserts ;-)
