Great Tooling Find

[roadie33]

Got some more tools out of the Evapo-Rust and getting ready to toss these transfer punches in.
I believe I might have enough Taps to last a while now.
I'm going to have to get another tool box to hold all of this now.








These were some of the Reamers that were never used. From 1/2" to 1". Also 3/4" and 7/8" taps.

Mike, the primary purpose of the pilot is to ensure concentricity to the thru-hole. Certainly they would reduce chatter if it fit well in the pilot hole, especially in the case of a deeply recessed counterbore. At times, the desired size counterbore is not a standard end mill, which many people use for the purpose.

Incidentally, IIRC correctly, fillister head machine screw heads have the same OD as the heads on SHCS.

Thanks for clearing that up for me Tony. Mike

Oh, on those Rigid dies, at least the top one is marked M.P.T for Male Pipe Thread.....so no good for bolts/screws. Olde tyme marking would have been IPT, for Iron Pipe Thread, or even MIPT, as if you could cut internal threads with them, ha.
