4.0 out of 5 stars Adjustible Wood Bit
The good points of the Irwin Lockhead Adjustable Wood Bit is that it gives you the ability to drill holes to your specific requirements.
The bad point is not really bad but the bit is a little difficult to adjust to get an exact hole size. There is a gague on the bit but it is only a rough measurement for the diameter that you need. To get an exact size you need to...

2.0 out of 5 stars Not What is Advertised
Don't be fooled by the poorly worded description, this bit does NOT include the attachment for drilling holes between 3" and 5" in Diameter. It only works from 7/8" to 3". Since I need a 4.75" hole it doesn't really do me any good!

4.0 out of 5 stars Adjustible Wood Bit, June 21, 2007

This review is from: Irwin #45002 Lockhead Adjustable Wood Bit (Misc.)
The good points of the Irwin Lockhead Adjustable Wood Bit is that it gives you the ability to drill holes to your specific requirements.
The bad point is not really bad but the bit is a little difficult to adjust to get an exact hole size. There is a gague on the bit but it is only a rough measurement for the diameter that you need. To get an exact size you need to drill a hole and measure the diameter and adjust the bit until you get the size needed. This bit is not balanced because of the offset to the adjustible cutter so it needs to be used in a drill press at slow speed.

3.0 out of 5 stars Not As Good As It Should Be, September 17, 2010

This review is from: Irwin #45002 Lockhead Adjustable Wood Bit (Misc.)
The set screw that must be loosened in order to adjust the cutting width was in so tight that I could not loosen it. I ended up having to take it to the local hardware store where they had to use a wrench to undo it. Also, the arm that moves back and forth to set the hole width does not slide smoothly, making it very difficult to adjust precisely.

I was disappointed that it made the circle just fine but then it was not very effect in drilling the hole very deep. The center hole was OK but the in between just didn't drill out very good at all?
