Engine valve hones ?

[CrotalusAtrox]

Picked these up at a sale and need some help identifying them. I think there used to hone valve seats but not sure My car mechanic skills are oil changes, brake changes and a few clutches.

Thanks

Not hones, but valve seat cutters. The shafts with the threaded ends are pilots, in different sizes to fit different valve guide sizes. Probably don't have much use or value nowadays, possibly might be useful to open up a seat for a larger valve before finish grinding. Seats are pretty much just ground today, or probably CNC machined.

Wow, that's an extensive set of pilots. Cutters look like good quality. It would be nice for someone with the drive tools they fit.

I have a similar set, but not nearly that many valve guide pilots. I've used it to recut the valve seats of many, many motorcycle engines, and also Model A Ford valve seats,too.

Looks like they are meant to be driven by hand, with a tee bar, looks like a bar laying on top of the pilots.

Those look like a set of K.O. Lee valve seat cutters I have somewhere.

One of the double-enders is clearly marked "Beard", a maker of reamers and cutting tools. It is likely that the others are a different brand.

It looks like a couple of the heads are designed to hold sandpaper, probably for smoothing out roughness from the cutters or polishing hardened seats.

agree with 454ragtop that is a hand operated valve seat cutter set.

can't tell if they are carbide or not, but keep in mind, there are lots of those sets still being sold today (most from India for some reason), and even many of the older ones are not for hardened valve seats.

I have a few just like those and looked into buying a set to complete it. almost everything I saw was noted as not for hardened seats. unless you get into the modern neway cutters with the carbide inserts. still useful though if you work on older stuff and small engines.
