thanks mc
I did come across those a while back,they describe them as standard and for brass alu and mild steel.
id like one capable of holding its own with titanium and stainless so not sure on that one although it does say else where on the site regarding stainless..The best grade broach for broaching stainless steel of all types is PM M-4 broaches and changing feeds and speeds it can be done.
im surprised china haven't jumped on these holders.
