Q: Can you tell which spade bit drilled 15 holes and which bit only drilled 1 hole?
A: It’s only a guess by looking at them. Even though most spade bits look the same, their tip design and mix of carbides can vary greatly, thereby varying their overall effectiveness.
The only real way to know how one bit compares to the other, is to physically test them again each other (in the same substrate, until failure). For this reason, we offer a Risk-Free Trial Pack & BOGO for first-time customers.
