Welcome to the forum.
I've never had to clean a bit. When the feed/speed is right you should get chips that carry the heat away from the bit. If you're getting dust or the bit is discolored then your feed is too slow for the given speed (rpm).How do folks clean their bits and how often?
Thanks. That bit went into the trash. Safety is more important than an Andrew Jackson or two.I've never had to clean a bit. When the feed/speed is right you should get chips that carry the heat away from the bit. If you're getting dust or the bit is discolored then your feed is too slow for the given speed (rpm).
What was your feed rate and rpm?I was pushing through the material at what I thought was a good pace
So I should either push harder (probably not a good idea) or slow down the rpms. Ok, I'll slow it down to a bit and see how that goes.Pushing it manually is bound to be inconsistent and likely not nearly fast enough feed rate for that high speed of the router.
I'll give you a for-instance; I cut the full depth of 1/2" Baltic Birch with a 1/4" compression bit running at 18k rpm (4HP spindle) and a feed rate of 175 ipm to 250 ipm. Running like that I produce chips, not dust, and the bit is no more than room temp when I finish a cut because the chips are carrying the heat away.
To be honest, this raised a bit of an eyebrow for me as well. I've always heard "no more than half the diameter of the bit per pass." Shaper seems to say effectively "full diameter of the bit per pass is ok." I planned to keep it at a 1/4" deep cut for the 1/4" bit, but slow it down to see how that changed things.Not being familiar with CNC systems it just seems counter intuitive to cut 1/2" deep on a single pass. But then again maybe CNC because of its consistency can do things we would not consider doing with a handheld router.
Whitesidewhat brand/material is the bit you're using
This bit is finished, totally cant be fixed and looks like it was massively overheated. You should post an imgae of how it was used as something went very wrong, no bit should look like this. NTotally makes sense. Here’s a couple pics.
