Step Drill Performance Test

[FerdinandII]

I wish he would have tried them out on some 304 stainless steel, but I have to give him props for at least using three different steels (including AR400 !!!).

Hello FerdinandII,
I watch him from time to time and this was a great review I too have a few in my tool set my favorite is my Klein brand I use my GreenLee hole punches a lot too .

Hello FerdinandII,
For sure and I do have some Amplifier projects to finish one of them is a Amplifier based on the Tube 5902 which was used for rocket guidance systems in the day .
Lately between work and repairing stuff for my customers my projects get put on the back burner .
