I have some lettering that is 1/4" tall. I have a 60-deg v-bit but it’s too large for the fine detail needed. I’m thinking a 30-deg would be good, but maybe a 15 or 22-deg would be better?
Any preferences on v-bit or tapers spiral ballnose bits (1/32")? I’ve read 30-deg is a good all around, but I can’t find any size of the engravings that’s it’s suitable for.
I use the Amana which we sell quite a bit for smaller/finer text/engraving:
Recommended bit angle for a given text size:
- <1" 45–60°
- 1–2" 60°
- 2–4" 60–90°
- 4–6" 90°
- 6–10" 90 to 120°
- greater than 10" 120° or greater
I have a 15 degree and a 20 degree vee bits that I use a lot. I got them from Amazon but they work very well.
I also have a 60 degree Groovee Jenny from Cadance Manufacturing that does a great job but would not work well for real small work. But for larger vcarve jobs it works well.
The finer the line the smaller the angle needs to be.
I have no doubt in recommending the 30° GrooVee Jenny downcut vbit for small letters. I mask the letter engraving with “shelf paper”, seal with shellac and paint.
These bits are an investment. I don’t think they’ll ever wear out.
You didn’t say material your working with but if it’s aluminum, the R.25mm tapered ball nose works great for me.
that’s a bit I’ve had for a long time that I still havn’t used. makes sense through I may have to finally try out the tapered ball mill in some brass
