View Full Version : Spade Drills

Picked up some spade drill inserts at a low price on ebay.I am planning to make a holder for these.The inserts are ~ 45mm or 1.772".
The overall lenght of the holder will be ~7.00" with a straight shank to fit in a large drill chuck.(I consider MT,but I may want to use in the mill as well)
Anybody ever make these and do you have any tips,etc.?

I would be sure and use something like treated 4140 or toolsteel,from a longevity stand point.
