I have a screw on my bike that has a stripped head. In searching for extractor type tools to resolve this problem I came across some 2 in 1 extractor bits that I had not seen before that are used in conjunction with a drill. An example is pictured below. The more common brands seem to be theSpin It Out by Easypower, Grabit by Alden or Speedout. Sears has a set that based on what I have read is the same thing as Grabit. These extractor tools are a 2 in 1 bit. One end of the bit 'drills' the head out somewhat. After drilling the bit is reversed to use the the extractor tip. This type of extractor tool looks pretty slick as compared to taking a regular drill bit and drilling the head of the fastener and then using an easy-out or similar extractor that you have to use with pliers or a wrench. Product reviews seem to vary by brand so I was wanting to see if any of you guys have used products like this and if so what brand you have and if you would recommend it or not.
