Q: What are the shank diameters?

Dear friend Head Diameter *Shank Diameter * Length 6.3MM: 6.3MM*5MM*37MM 8.3MM: 8.3MM*6MM*40MM 10.4MM:10.4MM*6MM*39MM 12.4MM:12.4MM*10MM*46MM 16.5MM:16.5MM*10MM*47MM Any question ,just feel free to tell us Regards Preamer

Q: How do these perform on stainless steel to deburr holes?

They work good in a2,d2, and stainless 304. I have several types, 60, 82, and 90 deg. I don't run a high rpm though. I use these in a hand drill motor and in my mill. Remember start slow, multi blade with light chip depth will give a good finish. They're though enough to champher an edge also, at least occasionally!

Q: What is the correct speed to avoid the chattering that leaves a very poor finish in the countersink?

Try running them at a higher speed and make sure EVERYTHING is as solidly locked down as possible. good luck
