Review on Irwin 88702 6 Extension Bit by Jimmy Hargrove

Sometimes you have to drill through the walls to get to the wiring. Telephone, cable TV and Internet use require their own access point. Most drills don't reach. This gadget does a great job. It is solid steel and feels heavy. The Allen key also holds the bit well. A little problem; The extension head is about 5/8" in diameter and the two small set screws usually stick out about 1/16". This puts a limit on how small a hole you can make at full range. However, I consider this extension to be a must-have in a drill set. Very well made, should last forever. Fast shipping too.
