Review on 🔪 Rocaris Stainless Steel High-Speed Hole Saw by Dean Ledet

If you are looking for inch sizes, skip this set. How do you say; I have used some on fiberglass, wood and plastic and they have worked very well. However, I always drilled a small pilot hole to help center the drill. I have not used any of the bits on steel or iron. The teeth are aggressive and I think this is best done on a drill at low speed with plenty of cutting fluid. The price is very attractive and each cutter comes in its own small plastic case. I love this little set and have found many uses for it even though it's metric! Buy it, you won't regret it!
