1/2" Indexable Boring Bar

[mikey]

This application is a through hole in cast iron, probably no more than .050'" to clean up a vise I bought a while back that's binding.

Of course I want to get tooling that will have other uses as well. Maybe a set like this?

I'd only need the longest one for my task, could buy a single but maybe I should be ready for future jobs....

If it were me, I would go for this M42 set from KBC Tools. Good guys, good tools.

I found this: Solid Carbide 1/2" Indexible Boring Bar. Yes, it's for a lathe and it's 5-1/2" long, but the 1/2" carbide shank will be stiffer than anything else you'll find

I have that exact bar... I've had no issues at all making light cuts at slower speeds in cast iron, steel, stainless, and aluminum. The only issue is the length, if you don't have a lot of clearance on your mill.

Saturday must be vise repair day. I'm tuning up a Reed 406 using cobalt bars, it's like cutting butter.

Hey Firstram,
Is that a Chandler boring head? I bought one and still haven't used it yet. I need to make an arbor for it first.
Does it work as good as they say?

It is, I bought it from a member on here. It's a little stiff but smooth, I'll pull it apart for a cleaning one of these days.
