As to the amount of force to apply when drilling holes, you need to consider the size of the bit, too. I've found that finer-gauge bits are impossible to use in any power tool, because they can bend unless the bit remains completely straight while drilling. Any movement, and they can snap.

I use Dremel's drill press rig, with the workpiece immobilized on the table, if I need power behind the bit. But for almost all drilling jobs, on metal or plastic, I've been able to use a pin vise. I use just enough pressure to drive the bit, and I can tell how the progress goes by the filings that come off.

Prost!

Ok I'll admit it.......what exactly is a pin vise?

How about a couple of photos.....and how its used.

All my vises are used to hold items used in car repairs

Hi, njja, here's a picture:



This version has one collet, but there are versions with a collet at each end, one for smaller bits and one for larger bits.

The collet is threaded, and loosening or tightening allows you to place a drill bit in the end, and they you use it for fine drilling.

Prost!

Sorry, the picture didn't end up where I expected it to in the text, but it should be clear.

As a tool, it has cross-over into fine machining and jewelry making/repair. But generally, the motive power (Mr. Big-Word, here) comes from your fingers, twisting the vise with the bit in place, and drilling into your stock.

Hope that helps, prost!

Thanks, I have seen those just never used one, or knew what it was called!

It certainly seems like a useful item, next time I visit my local hobby center, I

will make a point of picking one up!

Can't have to many tools in the hobby room!
