Title: R.R. Drill
Post by: ridjrunr on August 04, 2013, 01:14:51 PM
Speaking specifically about ram rod hole drills, is it best to have a 118 or 135 degree drill point or would a brad point be better versus a conventional point ? I got an extended drill that is good and true but the drill point is bad and needs to be reground and re sharpened.
Any input is appreciated.

Dan ,
a regular drill point will work but  IMO they like to drif to much. i no longer  use them for  RR  holes other then for a short  hole like on a  pistol .

 i have made a couple just from regulare cold roll . frankly i dont pay much attention to the angle but   to say they are rather flat .
 then just come back and  run your mill down one side  so as to make a 1/4 cut out of the bar.

Here is a 5/16" drill I just made. It is made of A2 tool steel and hardened to 59Rc. I believe this is what Charles is talking about. I know the picture is not the best but hope you get the idea.

Yes, I am familiar with gun drills. I just wasn't expecting them to be so usefull in wood. Especially with that point geometry. But I can see the benefit of the rigidity in that style.
Ya learn something new every day :toast

TOW sells ones like that pic of melsdad, they cut well--just go REALLY slow & clear chips each 1" or less.....Tom
