I have many Spetool bits. They have the database for Vectric which is excellent. Can't find any issues with any Spetool bit I have used. A few have broken - but that is on me for pushing it too hard ;)

I fell into making cabbage boards by chance, when my son-in-law loved the coasters, I laser engraved for him and asked about a cribbage board. We have a CNC machine that has a spindle, and I decided to give that a whirl to make one for him as a special present. Little did I know, the bit type and shape plays a huge role in the quality of the product as well as protecting your machine. I needed something that would work for pulling chips out of the cut, and not overheat and potentially cause a fire when drilling dozens of holes. This is a very nice bit and I could see it used in multiple applications, but the drilling of the holes in the cribbage board was my main purpose. It has definitely met and exceeded my expectations.

First individual bit I’ve bought and it works great. Used it on some hard wood to carve out letters and it was clean and never really got hot
