Tip for small drill bits.

[sak]

Was just wondering is anybody has a tip on small drillbits. My pinvise does not accept small drill bits anybody. Not sure if its just worn out. The pinvise does not grip the smaller bits. Perhaps a pinvise meant only for the smallest bits?

Thanks

There are different sizes of pin vises you have one that is tooo big for the smaller bits.

Some pin vises have different chucks which you have to change out for different size bits.

My pinvise has a chuck at both ends, one for small bits , one for larger. But even the small end wont grip them anymore, perhaps I will try the glue idea. Thank you

If you're using a Dremel, get yourself a universal chuck. It works like the chuck on regular drill.

Check the chuck on your pinvise. There are different sizes and you might just need a smaller one.

The smallest collets (collet is what they are called, as opposed to chucks FWIW) go down to infinity, meaning they should be able to close completely without any twist drill inserted in them. I have found, over time, that the infinity collet can gather dirt or modelbuilding debris in the slits chat are cut in them, at 90-degrees crossing at the exact middle of the collet when viewed from the end. Debris, even rust can happen in those slits, keeping them from being able to close completely when the threaded collar that tightens them is screwed in until it stops.

This debris or rust can be removed, by taking the collet out of the pinvise, and a piece of fresh, stiff 400-grit Wet-or-Dry sandpaper (used DRY please!) is slipped through the slots, from one side of the collet to the other, and then pulled/pushed back and forth (when you've done that to one side of the slit, remove the sandpaper, and flip it over to get the other side of the slit, then repeat this process for the slit that crosses the first one you cleaned. Every time I have done this (and my oldest pinvise is probably 35yrs old now), when I put the smallest of numbered twist drills in the thing, tighten it down, it holds the drill bit very tightly once again.

Or just get a drill press.
