Let’s see the difference between two V Bits. Oak Wood, motif size is 2.5" square.
Before and After.
Hmmm. Perhaps you could cut the same pattern at the same depth of cut? I can’t appreciate the difference. What are you seeing?
They’re same size, can’t you see the difference on sharp cut edges. I use to run same tool path twice to get a little better edges before. Second pattern came this clean at once.

1/8 bit only
I bought 1/4 inch*1/4inch 4 flutes straight shank, is this collet 4.5 mm ER11-A fit ?
A 4.5 mm collet equals a .177 inch shank size. A quarter inch shank is .25 inches so that collet is only about .073 inches (1.85mm) to small.
You will need a .25 inch collet for a .25 inch bit (with a .25 inch shank) It should be easy to find a .25 inch ER11 collet.
