IRWIN Screw Extractor Set, Hex Head, Multi-Spline, 25-Piece (53227)

Q: If any extractor is difficult to get a bite on a rounded out socket will a little hammering on the extractor damage it?

A few taps to "set" the extractor are fine. As you'll note, these are wedge-shaped (tapered) to jam the extractor into the bolt to grip it. Work slowly; i.e., start with a socket or regular wrench to grip and turn the extractor counter-clockwise after it's seated to remove the bolt. DON'T use a cordless drill to speed up the process; it will likely chew things up, making it worse (this is true with any extractor). These are also referred to as "easy-outs"; if used properly, they can save the day. These DO NOT work well with plastic pipe fittings, as they tend to expand the threads of the fitting, jamming it in even tighter. As Robert George mentions, don't drill the hole bigger than one-half (1/2) the diameter of the bolt you're trying to remove, as that will expand the metal threads to jam it in even tighter. On the smaller ones, you may need a sliding T-handle wrench (not included with this set) to grip the extractor to turn it. You can buy those separately (0-1/4" opening and 1/4"-1/2" opening), or you may already have them if you own a tap and die (thread-cutting) set.

Q: Does it include a 25/32

Yes it does. It has all sizes from 1/8" through 7/8" in 1/32" increments.

Q: Is that 3/8" drive on the back of these?

These extractors do not have a 3/8" drive in the back of them. Instead, they have a Hew-head and are designed to be used with either a 1/2," 5/8", 3/4", 7/8" or 1" socket or spanner (depending on screw size being extracted) to drive them.

Q: I have a 5 mil recessed hex bolt in a brake caliper that is stripped out. Can I use this to get the bolt out ?

Recommended tool to use would be a EX-2 Spiral Screw Extractor Part number 53402.
