Review on Betan Cornhole Drilling Adapter BI Metal by Jeff Westra

This was a real bargain and I wasn't expecting to get it. I bought this as a spare in case I break the new Spyder bit in the drywall. SUPERIOR QUALITY and performance outperforms others that cost 5X more at 1000%. After use there is no dullness, drilling 87 holes in drywall and plywood for Can Lights and still cutting just as well as the first hole. It was a really great price that I didn't expect. I will definitely buy more of these in other sizes.
