Hello everyone,

I am sorting out some inherited gear cutters. Most of them have the DP and tooth range stamped on them some also have the Pressure angle too.

There are quite a few that have simply P stamped on them where I would expect it to be DP. Do I assume that the P is just a shortened form of DP?

A few have nothing except the manufacturer's number, which I assume are "specials"?

Thanks,

Andrew.

P could stand for pitch which I would guess would be circular pitch (CP).

DP appears to stand for Diametrical Pitch. Number of teeth on a diameter of 1”?

Regards,

Jouke
