Cheap Reversible Threading Attachment?

[Boyan Silyavski]

Hi,

i will have to obtain a threading attachment, its not for production jobs, will be attached to my small mini mill BFE65 and used mostly for m10 and M8 , mild steel. And may be M4 eventually which i do in the thousands but till now using Makita cordless driver cause they are in brass and this way seems faster

Main problem being is that i discovered that on my belt grinder project, M10 and M8 have to be perfectly square for the rollers to be square to plates. And thats quite time consuming to do by hand.


I looked here and there but dont have the money for brand reversible heads.

Cheapest i found are the Soba, then slightly more expensive the red Vertex and then even more expensive the silver Vertex ones. /Chronox web site/

Any thoughts on that? Somebody have one of these? Do they work well? Of course i will be using brand machine taps and use the attachment on the mini mill.
