I am doing a lot of toy cars, trucks and so on and I need a reliable hole saw that does not "burn down" after a couple of uses. I am very careful using them (low speed, smooth pressing on the drill press...) but it doesn't help much. After some uses, they are already dull. By the way, I am using pine most of the time, it's not a hard wood.
I thought about buying them, but unfortunately in Europe you don't get a good offer as in the USA, where you can buy a bunch of them for not much money and in a different range of sizes. So I decided I would make mine as they suit me better.
Anyway, what is your experience with these hole saws and what kind of material (eventually producer) would you recommend?
Thank you for your comments.
