I bought a ‘99 BF6-31 and retrofitted it with a helical head. It was a custom order; I bought it through Byrd tool for just shy of $1k. Definitely worth it for the performance. There’s no comparison between carbide inserts and HSS knives.
?
I measured the existing cutter head and reverse engineered it to create a detailed dimensioned drawing which I sent to them. Their existing drawing of a BF6 cutter head didn’t match mine exactly. Fortunately everything fit with my custom one and it works great.?
it took them six months to deliver, twice their initial estimate. Communication was poor and only initiated by me; they would have been content to let me languish indefinitely. I’ll never buy another Byrd product again.
