What is a drill?
(OP)
Is it something that goes into a chuck. Or is it the whole machine?
During my shop training days we were always told that a "drill" goes into a chuck and a "drilling machine" turns the chuck and there is no such thing as a "drill bit". Similarly, "mill" - "milling machine".
If this is the case, what should I call my hand-held DIY tool? It seems silly to call it a machine.

RE: What is a drill?
Drill bit and drill machines will be nouns. May be drillng bit or drilling machine would be more appropriate.
The DYI tool is a machine.
RE: What is a drill?
RE: What is a drill?
a. a shaftlike tool with two or more cutting edges for making holes in firm materials, esp. by rotation.
b. a tool, esp. a hand tool, for holding and operating such a tool.

My OED is a little one from my school days. Held together with tape these days. When it finally crumbles I will cry.
RE: What is a drill?
It can be any number of tools; a hand cranked drill, a drill motor, a well drilling machine, a hardened steel shaft driven by a hammer wielding miner, even a device pulled by horses or a tractor for planting seeds. The thing that inserts or attaches to the tool is a "drill bit". The same bit can go into a hand drill or a drill motor or a drill press. The bit is NOT the drill, it cannot make a hole all by itself, it must be combined with a drill. The drill on the other hand can have multiple types of bits, many of which and not specifically called "drill bits" depending on their design. But when, for example, a Forstner bit is attached to a drill motor, the tool is still called a "drill", not a Forstner Actuator.
Also, anyone who has served in the military knows that a drill is not necessarily a useful tool!

RE: What is a drill?
I was thinking back to an advert by one of the industrial tool manufacturers, possibly Hilti, from ages ago. The tag line was "Hilti. Don't buy toys." An old friend kinda adopted it and mocks 'DIY' tools because he works in heavy construction with some fairly serious portable tools. I guess I've picked it up too!
Actually, some DIY tools just plain scare me. How anyone can make a safe 2000W angle grinder and sell it for £30 after shipping it halfway around the world (from China) beats me.

RE: What is a drill?
I hear you. Just a parallel to this, you can get in some trouble by referring to 'serious' items as 'jokes'. I got into some hot water because I referred to some 'technical' details we show on contract drawings as "cartoons" which I had picked from someone else. I always thought it was funny, one of my clients did not. In fact, when I pointed out to the contractor that the installation did not meet the information shown on one of the "details", the Owner sided with the contractor, reminding me that I had referred to that "detail" as a "cartoon' once, so it could not be taken seriously. Trust me this is a true story.
So you do not want someone getting injured usig a tool that you may have advise and blaming you that he was told that it was a toy!!.
By the way, my name is Rafiq. Never mentioned it here before.

I'm Jon, but I've been Scotty to friends since primary school. Jon really should be Jonathan, but that is reserved for Sundays and for those days when I'm in real trouble with my mother!
Anyway, I hope you sacked your client.

If you told me your family tree included the former Queen singer I'd be impressed!

Sorry to disappoint, but I chose my profession for a reason

RE: What is a drill?
Seriously; if I order a drill bit, I expect to receive a twisty thing that both makes and enters a hole.
If I order a drill motor, I expect to receive a powered device to turn the twisty thing.
If I am using SDS drill-bits, I order a Roto-hammer.
If I am breaking concrete, I order a very large Roto-hammer, complete with chisel bits and pointed bits (sometimes called bullpricks, and there are a couple of true stories of faux pas' on that name).
Reality check:
If I order a drill, or an SDS drill, I may be very frustrated, and have no-one to blame but myself.
I will order drill bits, drill motors and roto-hammers.
While the purists argue over semantics, my crew will have the correct tools and will be too busy making holes to join the argument.
Not to mention the purists who have an idle crew who have 3 times received drill bits and are still waiting for drill motors while someone complains that someone else doesn't know a drill from a drill.

To this day (practically every day) I still refer to these items as stated above and have never been asked "What do you mean"?
Nowadays --- who knows????
RE: What is a drill?
Aside from the "seed drill" there are several other devices on the farm that are called "drills".
There has got to be a "rock drill" as I have a gallon of rock drill oil.
The brace and bit was the first and only truly portable hand held drill-driver.
RE: What is a drill?
Two devices, The bit is the twisty thing and the brace is the crank that turns it.
As in;
"This bit is fine, but I need the other brace. The ratchet is broken on this brace."
re; My previous post, I have recently moved into an area where the "correct" name for a roto-hammer is a hammer drill. It only took us about 30 seconds to agree on the "correct" name.
"Do you mean a hammer drill?"
"Yes I do,"
As long as I am in this area the roto-hammer is the hammer drill.

RE: What is a drill?
Everyone grab your drill motor and put the bit into it.
Very well,
OK you guys in back too now!
What's next?
Anyone?
OK, you there.
Correct!
Before using the tool be sure you have a safe workplace, determine the suitability of the tool to the material, check the edge of the cutting tool, be certain of the suitability of your attire, and keep all foreign objects clear.
Now,,,,,, drill!!!
Everyone halt!!!
I see some of you forgot to check the direction of rotation!
Again,,, and,,,, GO!!!

I had a couple of left-handed drill bits that I used to create much fun around the shop floor...

RE: What is a drill?
This link contains discussion and a couple of images of a tool made by Watts Brothers Tool Works. I remember my father showing me pictures of one of these things a long time ago. It's a practical implementation of the Releaux mathematical principle. Took me a while on Google to find it!
