Good Day,

My name is ***** ***** I'll try to help you. Fosdick radial drills are no longer made anymore since 1982. I assume that you're referring to the power downfeed, is that right?

What material are you drilling? What's the HP of the drill? If it's the power feed that's your problem, have you tried smaller drills and is the feed rate exceeding the hole size and material hardness?


Customer: replied 2 years ago.
Drilling stainless steel 2 1/2"thick, this machine was made in 1951 has a 15hp motor
Was drilling @133rpm. I don't remember the feed rate
Expert:  Machinery Mark replied 2 years ago.
I will consult my tech. It seems that 133 rpm may be fast but I would like to know the feed rate at rpm/inch that you had set. Please send me the feed rate that you were using.
Customer: replied 2 years ago.
Sorry had to make sure my information was correct
The spindle speed was 31rpm, the feed rate was .004
Lever A was on number two but it does not shift in or out
The spindle stops under load

My repair tech is out of town because of the July 4th holiday and will be back Monday. I apologize for this delay, but he's repaired many Fosdick radial & sensitive radial drills. It sounds like the slip clutch inside the power feed may need some adjustment. The slip clutches are there to protect the machine's downfeed mechanism from stripping gears. Again, I appologize for the delay.
