We’ve reviewed Wiha screwdrivers and bit drivers, and I made the mistake recently of visiting the Wiha Tools website again. If you’re a tool fetishist like me, you won’t be able to leave their website without buying something!
They make all sorts of interesting tools that you never knew you needed.
I feel the urge to go back there soon — they have a new type of torque screwdriver that uses bits and measures down to 1 inch pound! You never know when you’ll need one, and if you do, and you don’t have it, it’s too late!
What drove me to the Wiha site this time was a recent oil change I did on my new (to me anyway) 1984 BMW R100RS “Last Edition”.
I had no idea what I was getting in to — the oil filter is hidden behind the fairing and involves removing the thermostat for the oil cooler.
Maybe it’s just me, and my Airhead-riding friends tell me that “you’ll get used to it”, but it was definitely the hardest oil filter change I ever attempted.
Part of the problem was, of course, not having the right tools (at least that’s the excuse I gave to my wife after spending 4 hours in the garage)!
I only have about a zillion dollars worth of tools, but I was shocked — SHOCKED — to find that I didn’t have a long enough hex wrench to do the job!
The stretch in and around the right-hand exhaust pipe, fairing and thermostat to reach the one single 5mm socket head cap screw that was holding me back from getting the thermostat housing off.
So as soon as I finished the job, I went online to see what Wiha offers to help solve the problem. I was originally looking for a set of long hex wrenches (see below), but I found the Wiha “Magic Ring” series of hex wrenches, and they looked like just the ticket.
The so-called “Magic Ring” is a patented Wiha invention (“Wiha” is from Willi Hahn). The Magic Ring hex wrenches have a ball end surrounded by a very small spring steel ring.
I’m guessing that these hex wrenches are made using the electrical discharge machining (EDM) process, because they appear to be of high precision and the curvature is of a type that I don’t think a normal machine tool could process.
The Magic Ring feature is available on a number of hex wrench types.
They include the Wiha “SoftFinish” drivers shown here; ball-end T-handle; ball-end L-keys; ball-end hex bits and standard hex wrenches. Each Wiha tool is available individually and in various combination sets.
The set shown here is from the 367-series, part number 36795. It includes a 3, 4, 5 and 6 mm driver.
It was only $17.46, and I figured I’d be better off with the smaller hex sizes, as the larger socket head cap screws are usually more accessible on a motorcycle.
There’s also a 6, 9 and 13 piece set, in both metric and inch sizes. The Wiha “SoftFinish” grips on these drivers are really nice.
They are not too soft, but give a great tactile feel and the curvature of the handle makes them a pleasure to use.
The Magic Ring feature works great; snap the end of the driver into the screw, and it really holds tight.
