The drill bits I had on hand didn't seem to work. So far this is Bosch TI2136 9/64 In. x 2-7/8 in. The titanium coated bit is useful for drilling holes in the utility spoons that I will be using for the hooks. Can't rate durability or longevity as I've only used this drill 4 times. I can say that this drill is way better than what I had on hand. happy
