3/4" Lathe Internal Boring Bar Turning Tool Holder S20R-MWLNR08 with Indexable Carbide Turning Insert WNMG432

Just what I needed

What a nice boring bar. I use it all the time. I use it on some things that I shouldn’t use it for but it works very well. Thank you for this.

The tool holder works well, clamps well and is pretty solid.The inserts are really cheap and wear quickly, but some high quality inserts. Once I swapped to good inserts the chips started flying.

No vibrations

This boarding bar comes with 11 inserts, the pack of 10 and mine was loaded with another. The WNMG inserts have 6 cutting edges so that is 66 indexes that you can do without buying a new pack of inserts. This is a very ridged bar it has a very negative rake so keep that in mind when ordering this bar. That was one of the pieces of information that was missing before I got mine.

Good for light duty hobbiest taking light cuts. not rigid enough for deeper boring jobs or heavier cuts. fairly decent if you only need to bore about 2.5 3" deep.

I could not ask for anything more....great product...

Fits perfectly in my 200 series tool holders
