Deep hole drill

A while back there was some discussion about making a drill longer than currently available. I made this one 40 years ago. I had never seen a wood tip on a drill in any store I had ever been in. Not sure if there were any WW specialty stores or not. Never thought about it. Lumber yards and hardware stores were my world.

It is a 3/8 inch x 12 drill bit. I held it in a vise on a drill press to drill a ¼” hole in the end. I used a 5” piece of ¼” drill rod for the extension. Soft solder was used for the joint.

To get the wood boring tip that would run true in curly maple, I hand ground it on the corner of a grinding wheel.

As PBS”S RED GREEN would say,”If women don’t find ya handsome they at least should find ya handy,” Very handy bit.

You made this when you were 5 years old? Man that is amazing! Curly maple was just invented & mountains of king crab were discovered in Alaska that year. I should know, I wrote the Bible! ;)

Studie~ On that Bible written thing where you wrote the part where the wife must obey the man, would it have killed you to have put in the word…silently!? Sheesh! Clearly you needed an editor. What was that, first draft?

cool. working as an electric contractor we used long drill bits all the time, from 12” to 8’ long (yes, thats 8 foot). they can be found in electric specialty stores (usually for contractors only). they are used mostly for remodeling jobs to drill in the walls and pass cables between floors without having to break open the walls. however, I’ve never seen a brad point on those they are all twisted ends – great job on the hand shaping of it!

Nice looking bit. I use similar tools here at the shop I work at. The point that you have ground on that, we call them sheet metal points. They are similar to a brad point, but work much better IMO. They work especially well in aluminum or any other soft metal, because they stay on center, the holes stay round, and if properly ground, the size is consistently spot on.

BAck when I made that, all the long drills we have today weren’t available in the wholesale houses.

When I first learned about that drill point, I ground a few to use on sheet metal, they do work great especially when yoiu have to have the hole precisely placed.
