Deckel Square Broach

In this weeknight short we make a small square broach on the Deckel single lip grinder. A buddy is working on a project to make some special collets for a tapping head and I thought this might help him. For a description of the project check out YT channel "outsidescrewball" and see what Chuck is working on. Another tuber, channel "James Kilroy" donated the tool steel used for the broach.
