OSCARBIDE 1/2" Shank Nickel Plated Indexable Lathe Grooving Parting Holder Heavy Duty with 10 Pieces GTN-2(QC1402) Carbide Inserts QA08R-20 Right -Hand Cut Off Tool

Worked great for making an axle c clip groove deeper! Took it slow with lots of lube on this hardened shaft 😆😆

Cut steel like butter…wish I could part off bigger pieces though!

Used one time and it worked great but then the second piece I had to part, the product broke. I was parting 3/4” mild steel rod and I was going slow so I wouldn’t put much pressure on the tool, but then all of a sudden the tool snapped. Don’t buy!!!

Richard and easy to use easy clean up

Tool cuts nicely, but can easily be overloaded. Tool cannot take any sideloads - accidental or otherwise. Please note that I am an amateur metalworker, so take this review as a grain of salt.

Good quality and performance for the size of the holder.

I was excited to get this tool because I am tired of dealing with the hassles of HSS parting tools. Upon arrival, it seemed like a nice, well designed tool. I used the tool for the first time yesterday. I was cutting some 1018 steel. I was using cutting fluid and light tool pressure taking a .002" cut. The tool made it about .060" into the work piece with no chatter or other issues and suddenly broke just behind and under the carbide insert. I believe that the steel that the tool is made of was too hard in this area and became brittle and broke like it was a piece of glass. Now I have a box of 10 of the GTN-2 carbide inserts with no tool to use them in. I purchased another parting tool from another company and have not had any issues. I really wanted to like this tool.

Accurate with great tooling longevity
