I’m trying to track these bits down after reading recommendations. ---

I havent gotten that far yet! Lol there are posts on her about that. If I remember correct the bit will leave burn marks when its getting dull but there may be other indicators, not sure. ---

I can tell when a bit is getting dull from the quality of the cut. You’ll get a little bit of hairiness from a sharp tool, but a dull one will give you a really ugly cut that you’ll spend forever cleaning up. I typically change out bits anywhere between 20-40 hrs of cutting depending on how hard I’ve been on the tool. Examples! 😃 'Cause if you’re like me, you need visuals. This is what I get from a fresh tool: ![IMG_20180805_162539](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/2X/5/5b8746f26a9bbc6971cbe964da6810f0656ba7aa.jpg) These parts were cut with a tool at the end of it’s life: ![IMG_20180805_110844](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/2X/5/5a789aae9ae122d41ac3d98ebf14b0149dac42c5.jpg) ---

No problem, I enjoy sharing as much as I can. I remember when I first started CNC machinist, I wish I had someone to help me figure it out. > [@Gero](#): > > Short I feel like that’s a first. I’ve told my wife before “I just need to make a quick post”, to which she responds: ![image](https://canada1.discourse-cdn.com/flex031/uploads/maslowcnc/original/2X/1/1ac55fa9252915820ef97209db56319156b88086.jpeg) But maybe that’s just me. ---
