Name this cut please

Ok, don't shoot me down in flames, but it was nearly 30 years ago I did my units so memory is not my strong point!  I have unit 13 and I think this was part of it, felling trees over twice guide bar........So you make your gob cut then bore into the centre of the gob and fan the tip of the bar around to remove the centre wood, then bore into the back of the tree parallel with the hinge, (leaving a little more to compensate for the centre bore) and fan around the back, to fell the tree. This cut is called?? TIA

I'd call that a letterbox. I think the letterbox name mainly refers to the bit you bore in through the back of the gob (that sweeps the middle of the tree out) but if you're doing that bit then you're doing the rest of it.

Yes it's what Husqvarna call sweep around ( or something like), with the inclusion of the letterbox bore.
