Miniature 4 mm ratchet wrench

[mklotz]

When I was making the adapter for 4mm bits, I noticed that the headroom needed to use the wrench was limited by the length of the bit. If the bits were shorter, they could be inserted into a smaller free space above the fastener. Not a real problem; when necessary, simply cut the 4mm bit shorter and gain a little clearance.

Then it occurred to me that the same thought applies to the 1/4" bits commonly used with this style wrench. I was ready to get out the disk grinder and make a set of amputated bits when it occurred to me that I couldn't be the first person to notice the occasional need of short bits. A quick check on Amazon proved this true...

This set is shown in the photo along with a short 3/16" hex bit compared with its normal sized brother.

Normal size length = 0.98"
Shortie length = 0.59

Headroom gained = 0.98 - 0.59 = 0.39"

Something to keep in mind if you do a lot of work in close quarters.
