[TenTec] Eagle Information

[Rick - NJ0IP / DJ0IP]

Small sockets from socket wrench sets work fine for limiting bit travel.

There are other ways to protect stuff inside. One is to use a short bit, 
I keep a few screw machine bits that are only about 1-1/2" long on hand. 
Another more versatile technique is to surround the drill bit with a 
sleeve letting only enough stick out to go through the metal. Sleeve can 
be brass or steel tubing, or a block of wood with a hole drilled through 
it. The nicest technique is to use a Whitney-Jensen hand punch, model No 
5 Jr if only 1-3/4" reach is needed and there's no flange or the model 
XX if more reach and depth is needed. These were far more price 
effective when I bought them than they are now. At least they don't drop 
drillings in the radio. You can capture drillings with a pocket of duct 
or masking tap under the hole.
