Well made and a big time saver,don’t hesitate just order. I’m ordering a second set. The shipping is fast. Thanks PwnCNC amazing product…
Bought 1/8 inch and 1/4 inch collars for CNC Router bits work great
They work really good. Now I don't have to zero my z. They save time.
I needed to do some fine detail work on a some 3D carvings: clearing with an 1/8” ball nose and extra detail with a 1mm ball nose. However, when I used a bit setter to swith between 1/8” and 1mm I seemed to be randomly either under cutting or over cutting.
The collars remove the random aspect which means I can, in a sense, fairly accurately specify the relative relationship (height) between the respective bits when they are mounted in the spindle. The difficulty is, of course, this takes some experimental runs as the collars can only be set to a degree of accuracy.
