Great Core Bit

by - verified purchaser
I used this to drill 17 holes trough a 3.5" thick brick facade. I chucked it up in a Milwaukee right angle drill @ 750 rpm. I used a 2x10 template w/ predrilled 3" holes to position the bit. It took a while to get the hang of drilling a straight hole by hand but after the first 4 holes it went smoother. This bit did a great job of clearing the debris and ran cool. Great product.
