🔧 Irwin Industrial Tools 3046008 3 Cutter: The Ultimate Tool for Precision and Efficiency Review

That's what you need for a 1.5 inch hole, just don't hit the metal, this bit on my hand drill will drill holes in about 5 seconds.

Good quick cut although I found the self feed to be a bit slower for me so I loop most of the threads off the pilot which gives me easier control of feed speed. Spencer Boyd [ .]

The 3x chisel is well made and cuts quickly, but it clogs with chips requiring the operator to stop after every half inch of drilling to clear the chips. At least that's how it was when I drilled white pine with it.
