For what precise purpose do you require a nice parallel hole ?

As this is clearly a hand operation presumbly the intention isn't to tap a thread ? Wriggling the drill about widens the opening and so a lightly undersized dril can be used allowing a tighter fit with tapered screws. Also the hole near the surface isn't important as what secures the screw is the head which is oversize for the hole and is drawn in by the thread lower down.

To impress people and exert power over them. Why else ? As this is supposedly in the interests of "security" people are allowed to do this as opposed to playing very loud music out of big louspeakers fitted to their outside walls. Which would be just as annoying but illegal.

Because power tools are a good excuse to browse catalogues and websites and then spend money on toys. More especially if its chargeable on expenses i.e. other people's money

One of my own. When a side road is blocked off by roadworks, why do the muppetts stick a big sign up 100 yards down on the main (unblocked) road saying ROAD AHEAD CLOSED ?

It made some sense when drilling holes in masonry for plugs that would be expanded by traditional (i.e. taper thread) wood screws. It does not real serve any purpose these days with modern screws.

They can be dumb and experienced!

Sometimes they want "range" but can't be arsed to place the lamp high enough up to get it with a sensible bean direction.

Perhaps after you have fitted it a few times, you remember the process without needing to check the instructions.

Speed / lack of hand tool skills.

Is it a wiggle or just repeatedly withdrawing and inserting again to remove the dust from within the hole?

Fitted in the daylight hours so they don't know where it's pointed?

i) this item must be fitted by a registered/qualified tradesman so we haven't included any instructions. I've seen this warning on items that could have been fitted in many incorrect ways and for an incompetent tradesman probably has been.

ii) a tradesman has possible fitted the item before and doesn't need to read the instructions again

iii) some items come with optional parts and/or additional parts to suite different applications.

iv) sometimes its better to discard a manufacturers part and fit a better generic part. Recently I've discarded a really crap mains connector on a light and replaced it with something much better.

Often saves time. Can minimise repetitive strain injuries.

Quite. Would be easy enough to have movable arrows to indicate it's actually a side road to the left or right.

I only do this when I'm drilling a slightly undersized hole because the substrate is weak.

The ones that do this don't think about it. Experience doesn't always improve skill. You can't educate pork.

When I was working and I was assembling something that I'd assembles a thousand times before I relied on memory. Apart from that, manufacturers' instructions are often a bit cloud-cuckoo.

In my last ten years of work, and in my retirement, arthritis and RSI make the intensive use of some hand tools impossible.

As a footnote, I have many fond memories of the days when I used to work alongside my dad. In his eighties and early nineties he did a lot in the workshop, mostly building TV system head-ends, but also doing woodwork. His basic attitude was that he didn't use power tools, but as time begun to weary him I was able to slowly win him over to such fiendish devices as the dremmel, the electric drill, and even the jigsaw. I have five farm gates, and he made them all. Mortice holes were hand drilled then hand chiselled; none of this router nonsense.

Either that or splash out on two signs. NEXT LEFT TURNING CLOSED and NEXT RIGHT TURNING CLOSED. Although then the muppets would probably still use the wrong one in any case. So maybe arrows as well, just to be sure.

I wouldn't mind but the actual side road is completely blocked off with waist high red and white plastic cones, guarding a 6ft deep trench. Basically a person would need to be brain dead to try and drive down it, in the first place.

But maybe its no surprise what with the low traffic neighbourhoods and half the roads already blocked off with planters and concrete blocks.

Covid 19, a No Deal Brexit, and now half the roads blocked off. You simply couldn't make it up, if you tried.

damages drill bits & sometimes drills too

as above, lack of knowledge

why would one read something 100 times? Oughta read it once though! Though most is just daft guff.

it's way quicker. Time is money.

Why do they have the *roadworks planned* signs in such small print that only pedestrians know when it is going to happen?

Speaking of which.. HertsCC failed to collect a road closure sign here if anyone has a need:-)

And surely the spiral on a drill clears the debris from the hole. I can't think of an application that benefits from a tapered hole.

I always throw away the screw plugs that come with products and use a decent brand.

It's supposed to clear it, usually does with masonry but not with wood.

You really couldn't. Round here, a main road, the A24 which is a high street with two lanes in each direction, now has fenced off bike lanes. Giving half the road exclusively to cyclists. Meaning buses now stop in the middle of the road. Blocking it to emergency vehicles - with a major hospital nearby.

Why is the country now run by cretins?

These black on yellow temporary signs are designed not to be read on the move. An excellent way to increase the income from fines.

I don't, but I might carefully pull the bit out while it is still rotating to pull out the dust.

why do farmers use £100,000 tractors to do a job that an old MF-35 could do ?.

That doesn't make sense. Only the deepest part of the hole is widened and that is where the point of the screw ends up, so the plug is never expanded into the widened hole, surely ?.

Pigs are very clever animals. And they keep their sleeping quarters clean to. They only crap elsewhere.

So they can sit in an air conditioned cab and play computer games while the sat nav looks after the steering:-)

Actually the Fergy 35 would only pull a 2 furrow conventional plough and might need water in the wheels to do that in clay. A modern 4 wheel drive might pull a 7 furrow reversible which avoids land working. Perhaps 5 times the work rate. New cost about £885. What would 5 times that be in today's money?

The normal "wiggle" (or orbit might be a better term) will move the shaft of the drill nearest the chuck more than that at the point. Creating a conical hole with the widest diameter at the surface.
