Do they make a hole saw set that lasts?
I've had sterett , greenlee, Bosch , Milwaukee , and countless others .
They are all hard to keep.
Carbide being best .
Not sure if they were worth the money though.
My favorite is still the Blair Holecutters. The make both carbide and standard ones, I have not tried the carbide one. The key is slow RPMs and heavy pressure. Most smaller drill motors cannot not provide enough torque to spin the cutter at a low enough speed.
