Hi folks,
I make parts out of baltic birch and some areas of those parts can be relatively thin (like 1/4"). In those areas, a common problem I have is that the upper or lower layer chips away. I've tried down cut and up cut bits and have found that the problem is less overall with non-spiral, straight bits, but still too common. I generally use 3/16" to 3/8" bits. I've tried faster feed rates, slower feed rates and haven't found that there is much difference. For you more experienced people, my question is, Is my goal to completely or nearly eliminate those pull outs unrealistic? Or is there a sweet spot I might find with the bit type/size, feed rate, etc.?
Sorry if this topic is covered well somewhere else - I searched and didn't find much. Would love to peruse other existing threads if you know of any.
Cheers!
