Yes, It does use the Hardinge 4c collets. I am going to look for some of them to hold various shank sizes.
The difference I see between the 374 and 380 is the motor size. My 380 has a full size 1/2 Hp motor. The
manual I downloaded from a site for the 374 looks like the motor is smaller. Don't know for sure. If a HSM
wanted a tool and cutter grinder for not too much money, they should consider one of these if they see one.
It has very nice linear bearings / roller bearings that the table "slides" on. I will report back on how well it works
when I get it working.
