Anyone know who has .029 OD under size straight pins &

who makes a STRONG .035 drill bit to fit a regular chuck hand drill?

If you are only going to shop hobby shops, X-acto has drill bits even smaller than that. They only come as strong as they are. 

They are HSS. I don't break too many of them.

I just got some pins from Walmart to pin 1/24 bodies and for pinning my HO chassis at the rear axle.

Irwin makes small bits also. I use a .032 or .035 for cleaning out the pin tubes.

A motor is only as fast as the chassis it's in.

By asking that the drill "fit" a hand drill chuck, are you looking for something with a, say, 1/8 shank and then the .035 (#65) drill size ground the rest of the way? Those are called circuit board drills... only bad part is they're carbide. I have never seen them in HSS...

Hi John,

I don't know where reduced shank very small drill bits can be had, but you can get hex-shank drill chucks to fit your hand drill's "regular" 1/4" or "3/8" chuck.  These should be able to hold down to 1/32" drill bits or even smaller.

I just chuck the tiny bits into the mini-drill bit casing, then chuck the casing into my drill motor.

The OD is .373"so it fits a 3/8" chuck.

I purchased a StyleX (DT-626) Drill Bit Kit in Seoul, Korea, last week for about $13 US  :)

 

It contains 14 bits ranging in size from .02 to 1.5 mm in 0.1 increments.

 

The 0.7 mm bit equals 0.02755"

Carbide will break if you bend it at all while drilling.  You may want to try a cobalt drill bit, wire size #65. 

 

You can order them from McMaster Carr, part#
