Review on Migiwata Fractional Cobalt Steel Twist Cutting Tools by Logan Broadnax

We are building a large steel building that will require over 4,000 pre-drilled screw holes. We've tried every brand from every big store. After stock ran out (small town, limited supply) I searched the internet and ordered bits from a few different sellers to compare. Those were the best of them all. We are on the fourth box. They just feel sharper and last MUCH longer. Not to mention the dollars saved compared to $3-4 apiece at the store. And yes, we are cruel to them, we have neither the time nor the patience to coddle them. We chew them and spit them out. So for us they were the best and I will order more if we need them. Many Thanks.
