A fine parting tool

[Kevin DParticipant @kevind]

A HSS broken cutting saw blade was begging for a second life. Taper groung faces 80dia. x 1.6 thick HSS Co5% used for cutting s/s tube. When ground it gives about 10mm cutting depth. The first design has the blade center 1mm below lathe center height. It allows the blade to be rotated up to tool center and gives some top rake.The next design will only have 0.5mm below. This would avoid excessive grinding to obtain front clearance. If it digs in it rotates down and away from work. Great for circlip and oring grooves.

Plenty of scope for resharpening there

Nice one, a really useful bit of recycling there

It's an old idea but a good idea, If memory serves Herbert or Ward used the same system on capstans

I came across circular form tools in the 70s on CVA cam autos. Good way to use up a small slitting saw.
