I thought a helical one would be best due to the intermittent nature of the cut, but as John S said it only needed witness marks clean across the depth of each jaw. I had the main spindle turning about 100 rpm and the opposing one counter revolving again about 100 rpm, and fed the tool in by hand and it was far less painful than I'd feared. Although steel, the jaws are in the soft state. |
