STUB DRILL BITS
$4.10
There are 3 stub drill bit sizes:
The 5/16″ and 11/32″ stub drill bits have a 1 3/4″ flute length and the total length is 3 1/16″. The standard wood bit is longer and tends to “wander” if it hits a tight wood grain.
You may also like to buy the Bottoming Tap which cuts threads to the flat bottom. This is recommended for the hard exotic wood.
The 7/16″ stub bit is used for the Threaded Inserts Some wood or especially acrylic and resins do not hold threads well and the brass inserts make it a lot easier.
Lathes Specifications: here is a list of lathe spindle sizes and Morse taper if you are not sure.
These drill bits are made in America

The stubby bit results in virtually no deflection of the bit when drilling the hole in a bottle stopper. Accordingly, the result is a well centered hole into which to mount the blank to the bottle stopper mandrel.

I am pleased with the drill bit, it is just what I was looking for. The rapid delivery was very much appreciated, Ruth said 2 to 3 days and I thought, “yeah right, I’ll see it in a week or so.” Two days later it was in my mail box. Thank you. Great system.
