SlimFix Locking 1/4" Bit Holder For 1/4" Insert Bits Impact Rated

Rated 4 out of 5 by Michael Z. from Good design; wider applications? Works smoothly and locks securely with 1" insert bits; also seems to retain full-length power bits just fine, although for some reason this feature is omitted from the specs (??) It thus appears pretty competitive with the other W's locking bit holder system, which also (explicitly) handles both. The Wiha is much slimmer for reaching fasteners in close quarters (11mm vs. 15mm diameter), a major advantage. On the other hand, the business end of the Wiha is also somewhat longer (43 vs 25mm) and, unlike the competitor, the Wiha takes two hands to change bits, since its unlocking action is toward the handle.Wiha doesn't currently appear to offer a screwdriver handle with this system, which is puzzling. Their 26--in-1 handle has a similar looking bit chuck, but it's incompatible with standard bits.

Rated 4 out of 5 by Brian K. from Nice bit holder I like the locking feature of the bit holder, but you can't stick it all the way down in a battery operated driver as the locking feature is unable to work properly. You have to keep it about 1/2" or so from bottoming out on your driver when mounting it.

Rated 5 out of 5 by Bill from Perfect This holder works great for our impact drivers. We can quickly and easily change bits depending on the job. We have them for everyone in my department.

Rated 5 out of 5 by Adam K. from Best bitholder I've ever used Works fantastic with the 29mm bits. 25mm bit's sit a little deep but not so much with it's a problem
