Drilling spring steel

[Godwin Hampton]

Jordan,

Twist drills have a flaw; the point has a small edge between the cutting edges, and on hard surfaces this edge does not dig in to allow the cutting edges to do their thing! Try centre-punching the plate heavily where you want the hole, the 'point' falls in there, allowing the cutting edges to make contact!

Slow speed, and generous amounts of cutting oil.

And Good Luck!
