Coated Bits vs. Non-Coated
I've see there are both types and wonder what others think about the cost difference vs. durability. In your opinion, is it worth the extra money? There's so much experience here I'd like to know what you've discovered.

I use carbide bits and don't have any problem with burning or tear out.

Thank you Ray. I'll order the less expensive ones. My wife will like that.raymassez wrote:I use carbide bits and don't have any problem with burning or tear out.

Re: Coated Bits vs. Non-Coated
I have near 40 years as an engineer in metal cutting.
I have conducted tests and Design of Experiments on various coatings.
I will vouch for good coatings, in metal cutting, but not in wood.
Wood does not need coatings and money spend on coatings for wood is not a good investment.
I will not use cheap cutters. I am a true blue believer in using the best cutters I can get - but not better than I need.
I do NOT buy coatings for my woodworking tools.
Coatings add lubricity (slippery) to the tool surface and they add hardness. They help with chip welding on the cutting edge of the tool. Wood does not "weld" to the tool surface.
