Review on Irwin 88702 6 Extension Bit by Jay Kenville

Needed a forstner bit extension to drill holes in wall studs as the bit needs to be securely attached to the extension as forstner bits don't reverse as well as standard bits. This tends to make them jump out of the expansion, and if they're inside the wall that's a problem. Should be useful for reaming and threading. Good that it also has two adjusting screws.
