Deep sockets are one of those tools that, every so often, I could’ve really used but managed to get along without. So I got a , Wera’s 05004525001 deep socket set (1/4-inch drive). It’s got 9 pieces, covering M5 up to M13 and including the one half-size (M5.5) that Wera offers for these. Their complete range of deep sockets, at least for 1/4-inch drive, runs from M4 up to M15. I tend to work on smaller contraptions with smaller pieces, so I bought an M4 socket individually, removed the M13 socket and stowed it away, bumped the remaining sockets down by one, and seated the M4 at the front.
At the same time, I got the smallest Mitutoyo feeler gauge (184-305s) and radius gauge (186-110) sets from a different retailer. There are 13 leaves in the feeler/thickness gauge set and it spans 0.5-1mm, in 0.05mm intervals between 0.05 and 0.3mm and then in 0.1mm jumps from 0.4 – 1mm. The radius gauges run from 0.4mm to 6mm this way: 0.4mm, 0.8mm, 1mm, 1.2mm, 1.5mm, and 1.6mm and then from 1.75 to 3mm at 0.25mm intervals and from 3.5 to 6mm at 0.5mm intervals.
I also wanted small needle/pin gauges. This time, I went cheap and picked up a Chinese set that covers apertures from 0.1 up to 1.0 mm at 0.01mm intervals. The image above gives you an idea of the packaging. It’s not a photo of my set but rather a couple of images from the seller’s product page that I’ve combined for illustrative purposes.
