Hi all,
I'm having a problem broaching a simple 3/16" square keyway (1.25" LOC) in the 5/8" bore of a hub I made. I don't do this often and in the past I've had no problem. But this last time I can't keep the broach from running too deep on the backside of hub. It's like the cutting action of the broach is pulling the broach into the hub and away from the guide bushing. I didn't have the proper size (B) broach and purchased an inexpensive import and I'm wondering if perhaps the cutting angle on the teeth is ground wrong. My other broaches are all Dumont and I've had no problem with them. Or is this a setup/execution problem?
