Review on Neiko 10197A 5 Piece Titanium Drill Set by Michael Shim

For the price I think they will be good for my occasional needs - and you might be lucky. Three of the five bits in the set I received had poorly formed guides that didn't drill well when testing PVC and steel electrical boxes. Once the steps are in they cut normally so an existing hole can be drilled or knocked out to a larger size. Full diameter treads are only 1/8" deep so you have to decide what to do with the thicker material. I don't know how durable they will be but I don't use them daily for a living. The case is a little bulky but durable and prevents bits from getting lost or damaged between jobs.
