I had a #6 screw that was broken off 3/4 oak and hoped that this would be the ticket to remove it and minimize the finishing process. The screw extractor simply just broke into three pieces within about 14 seconds of drilling. I was still able to remove the screw but so much for a nice tight fit for a 3/8 dowel. I was required to chip away the 1/4 inch of wood that was cut and then use needle nose pliers to unscrew the screw. If I knew it would last 14 seconds at $13.99 ($1 per second) and end up with a loose fitting 3/8 hole I would have just used a 1/2" hole bit (which I already have) and used a 1/2" dowel
Searched everywhere for this
Use this in boat building application to remove broken fastenings. Have long wanted a small hole saw like this. More length would be better though.
The item is only 2" long and the length is quickly consumed by properly setting it in a chuck. This item would undoubtedly work wonders utilized as shown in the picture. I unfortunately had a deep recessed screw to remove. Heading the warnings about heat and burning the wood, I took my time and slowly drilled in and stopping for all parts to cool. It was at the last part where I hit a knot and the extractor just simply broke. The metal it is made out of is brittle - I only assume they did not heat temper it for strength. Now I had a screw and a extractor stuck in the wood. I would recommend this to a friend - with a very big WARNING.
Useful but needs care
Comes with detailed instructions about how not to squash it in a drill chuck. But better solution would be a separate insertable solid metal core (not necessarily steel, could be light alloy). (Of course I made up my own with an old bolt of matching size.)
Every shop should have this
Easy to use.
