Cuts well in various sizes

Cuts well in various sizes and does well. Runs clean, no scratches. My only concern is that it takes some time and patience to adjust the bit to the exact size you want to cut. You either press the bit and it doesn't move, or you press it and it moves 1/8 inch. It's hard to find a happy medium with a turnbuckle and thread combination. Trial cut, readjustment, trial cut, breakage, post-processing.

Pros
  • Tools and Housewares
Cons
  • Slightly wrinkled

Adjustable Wood Drill Bit

The benefit of the Irwin Lockhead Adjustable Wood Drill Bit is that it gives you the ability to drill holes that meet your specific needs. a little tricky to set up to get the exact hole size. There is a gauge on the bit but this is only a rough measure of the diameter you will need. To get an accurate size you need to drill a hole, measure the diameter and adjust the drill bit until you get the right size. This drill bit is not balanced due to the misalignment of the adjustable cutting edge…

Cons
  • Obsolete Model

All in all, not bad with a little fix

Irwin Adjustable Wood Drill Bit works once you take out the crappy set screw that comes with the kit and buy yourself a new one. It's a little difficult to use as it's unbalanced. As for the accuracy of the scale, I had no problems. I've been looking for one of these things for a while and I'm happy to say it works well for me. UPDATE Jan 2013 I still use this from time to time. My spare screw is still holding. I found that you actually have to tighten the screw to keep the blade from moving…
