Rock Creature
That's me taking a picture of it at Newport Beach R.I. Notice its head on the right, one eye is showing. It appears to have a trunk or some sort of a beak. On the left of the body you can see its big fat tail that curled up as it died. It has a big round body. Its legs are not seen, they're under the body. I call it the Rock Creature because it has the ability to blend in with the many boulders along Newport shores.

“A Cordless Drill Your Wife Will Actually Appreciate”
Well, anyone with arthritic hands would appreciate it. That statement came from a review of a Bosch PS20 Cordless Drill/Driver. This is just one of many, smaller but just as powerful, drills on the market using Lithium-Ion batteries. This Bosch drill has a chuck that accepts any ¼” hex bit. It has a locking sleeve for locking and releasing bits.
If you haven’t converted to a drill powered by a Lithium-Ion battery and using the ¼” Hex Chuck yet, then you should consider doing it. Portable cordless drills are ideal for driving in screws and for light and medium drilling.
You probably already have a cordless drill and more then likely it’s powered by NiCad batteries. Compare the two drills I have. The bigger NiCad one is my original. The smaller one, a Christmas present from my Son-in-Law uses a Li-Ion battery. That’s a big difference in size and weight.
Besides being lighter, the smaller drill’s center of gravity is closer to your hand so there’s less stress on your wrists. The bigger drill is more front-heavy which puts more torque on your wrist joint.
The next picture shows some of the hex bits that I use. The drill on the left is crimped inside the hex shank. The one next to it is inside a collet. I will not buy more of the crimp types. Some of the drill bits are not crimped tight enough. I’ve had some of their shanks spin out of the drill bits.
To the right of the collet based drill bit is the hex shank with the sleeve unscrewed from the collet. You can buy just a set of collet type hex shanks and insert your own drill bits into them.
The beauty of the collet based drill bit is that you can replace worn or broken bits. The outside of the collet is threaded. The drill inside the collet is tightened with a sleeve that is screwed on to the collet.

In addition, these collets will accept a small range of other drill bit sizes, not just the drill bit size that is labeled on the collet. So if the bit is 3/16 for example, you may be able to replace it with its (closest) metric equivalent or a number sized drill bit.
The only issue in drilling with this drill is that the hex chuck has a little play in it. That makes the drill bit wobble. You can also get a Li-Ion drill with a standard 3-jaw drill chuck. That may be preferable if you need to do precise drilling. You still can drive hex bits with it of course. In addition you can insert a hex drive into the drill and have a quick change hex bit drive drill.
The next item is a bit extension. The rightmost one is a Drive Guide. It is basically a magnetic bit holder with an outer sliding sleeve. Its purpose is to hold the head of the screw from sliding off the screwdriver bit. It is most useful for driving or removing slotted head screws.
On the bottom left is a socket adapter. It consists of a ¼” hex shank at one end and a ¼” square shank at the other end. It is used to drive ¼” drive sockets. Next to this shank is a ½”, ¼” drive, socket
The last 2 items is of my own invention. The first is a ¼” hex bit (Allen wrench) attached to a 3/8” socket drive. You would use a 3/8” Socket Wrench to tighten or loosen ¼” hex screws (Allen screws). In this case I reverse its function. The last item to the right is a scrap piece of 3/8” square aluminum stock. It goes inside the socket drive. I insert the hex end into my Bosh drill.
If you’re familiar with the 3-Jaw Lathe Chuck then you know what a pain it is to open or close the jaws using the chuck key. This system gives me a Powered Lathe Chuck Key.
A word of caution. Don’t mess with a Li-Ion battery. You may have replaced dead Ni-Cad cells, as I have in the past, but these batteries are different. Don’t take my word for it, do the research yourself.
