@Wayne..."to find a new electric drill which is NOT made in China."

Good luck with that.  I'll be interested to see if anyone does come up with anything.

PS...Just read Antedeluvian's reply.  I have a couple of fairly recent De Walt tools at work, I'll check them.

And I think someone else might have some Milwaukee ones, if I find any I'll check them too.

My immediate problem is to find a new electric drill which is NOT made in China. 

I don't know, but if any company does make in the US (based on its name) it would be Milwaukee Tools.

I would also suggest looking at Ridgid Tools

I just found this site for de Walt that claims that they are US build

Which I found on a google search "us made cordless power tools". Seems there may be a few more.

 Elsewhere someone suggested Snap-On

But I think you are going to have to ask them all directly.

Interesting collection David.  I also have many of the gadgets you've shown.

My immediate problem is to find a new electric drill which is NOT made in China.  I have queried many suppliers and manufacturers looking for such and have come up empty.  All of the quality and well-known Japanese brands are made in China, and even Bosch is made in Malaysia.

Help from readers?  Does anyone know of a brand guaranteed to be US or European/Scandanavian made?

Cheers, Wayne

@antedeluvian....I was once looking at my stepped drills and wondering if you had to have the steps, or whther they would work as a cone.  Obviously they do!

Since writing the article and writing this I have used a good few of the tools I mentioned in a videoconference installation at work.

One more kind of drill bit

I have several REALLY LONG drill bits specifically designed for running cables through walls etc. Diameter ranges from 3/8 to 1 inch, with length about 60 inches.  Shanks are designed to have some flexibility and also have holes for pulling a string through after completing the hole.  I use this with (and store with) a set of fiberglass flex rods that screw together to make one 30 feet long.  Great for pulling cables through wiring chases, over suspended ceilings, etc.  I've used these to run both Cat5/6 and coax in several houses (and my office, until management insisted that we had to use licensed electricians for this).  PS: I run a LOOP of string the entire length of the vertical or horizontal run, and use {like pulleys over nails at each end) so I can access the same locations repeatedly to run wires.

I have a variation on the stepped drill bits you show. They are called cone-cuts and they are exactly that- cones wtihout the steps that you have. It seems to me that the original manufacturer doesn't exist any more, but Here is a similar part or the ones in the middle here.

I actually have two for different hole sizes. The porblem as you might guess is actually drilling out the right diameter. I did see a suggestion of using a washer of the right size (or slightly smaller) fitted over the bit to help stop at the right point.

@Max:

 

Yeah, that's me - I have whole series of stuff involving firearms.  That was a lucky shot, but I got about 3 or 4 on that day that are just beautiful.  This is the one I like the most.

 

I even caught the bullet comming down the barrel in a .45 pistol, too!

If you aren't already aware of them, you might like to know about Clecos: http://www.rivetsonline.com/cleco.html which are to sheet-metal working what pins are to dress-making. They're a temporary fastener to hold 2 pieces aligned together while they are drilled or riveted.

If you want a lot of holes evenly spaced, an adjustable rivet spacer is a alternative http://www.aircraftspruce.com/catalog/topages/rivspacer.php?clickkey=6495 to a sheet of perf-board, but whether the extra expense is justified would depend on how important regularity and particular spacing is.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
