Rated 4 out of 5 by Nice tool, needs a minor improvement This is a very nice tool that works very well. I bought it to use with large hole saws for wood and they work together quite well. This is a very solid tool that gives the user a lot of confidence in the kind of job that has a relatively high risk of both injury and part damage. The only real flaw I found is that this otherwise solidly built chuck has a set screw lock for the arbor that has an allen key size of apparently 2mm (that's not actually indicated anywhere, but 3/32 is clearly too large and 5/64 is too small). What this means is that the first time I tried to tighten down the set screw it rounded out and the arbor was permanantly stuck with the hole saw I'd just put in place. After considerable work I was able to loosen the set screw just enough that I can engage and disengage the arbor lock now to trade out hole saws, but I'll never be able to lock it down again. If I could somehow back the set screw the rest of the way out I could replace it with a case-hardened set screw, or better yet just a machine screw so I could get a good hold on it if it jammed again, but that doesn't seem to be in the cards. It seems to operate safely without locking down the arbor, so it's still a functioning tool and it otherwise does its job well. The design should be modified to allow a slightly larger set screw with a larger allen key size so that it won't be so easily damaged. March 12, 2013
