| Split die screw point angle |
| (1/1) |
| hosinsky:
I have a split die, M12x1.75, and need to make a holder for it to be able to use it. The conical screw, which keeps the die open, what angle should the point have? Goran |

Goran, I made a tailstock die holder for my lathe with the "die expander" screws 60 degrees included angle. I copied that from the screw in an old Presto die stock, which looked about 60 degrees, and used silver steel/drill rod and hardened it afterwards, to make it last a bit longer when used to expand HSS dies. I don't think the exact angle is very important. Andy |
