Review on High-Performance EZARC Carbide Hole Saw For Cutting Stainless Steel And Sheet Metal - 1-1/8" (29Mm) Hole Cutter by Michael Miles

I have only drilled 8 holes in 3/16 steel so far. The 3/4 bit is holding up well and cuts fine. Use plenty of cutting oil and go slowly. The pilot bits are not good, predrill all your centering holes with 1/4 drill bit so the pilot bit is just centering instead of cutting. If you order this 3/4 bit or any other, be sure to order multiple pilot bits, you won’t be sorry.
