The best wood lathe drill . . .

I’ve been away for a while and am very pleased to see that I am continue to get a few hits on this site.
As a wood turner who generally uses a drill to set the final dept of many of my turnings I have always struggled with the center hole and the square sides that most drills leave at the bottom of a hole. Another problem I was always dealing with was the heat build up from friction and the difficulty in removing bits once the hole was complete.

I have now developed a way to make a nice round bottomed hole by repurposing a wood drilling “Speed Bit”.


These reshaped bits drill really well and easily with very little heat,to just about any dept a person could want to drill. There are lots of extension available which allow holes as deep as one would want to go.

The cutting action is smooth and clean in hard and soft woods when these bits are held in a chuck in the lathe tail stock. They cut beautifully in end and side grain.

I currently make them in three sizes 1/2″ – 3/4″ – 1″.

If you ever use a drill bit to set the depth of a bowl, box or hollow form you must try this bit!

Should you wish to try one, please email me for pricing and shipping costs.



  1. I would like more info on your rounded speed bore for making round bottom holes, can you make it bigger to create an egg cup ?? percy 450 292 0079

    • I haven’t made any larger sizes which means I would need to remake my jig but I’m certain it could be done.
      Percy, do you have any idea what size would be needed? Would you be drilling into end grain or side grain?

    • Sorry about that! I will for sure have to take another look at my pages to be sure it is easy to reply to me.
      I’m hopeful that you can wait for a week or so for a response as I am currently away from my office and shop on vacation.
