Well, I'm not usually one to advocate cheap tools from lands far away. But I first bought an internal (ID) grooving tool with a specific carbide insert which I normally don't use. The bar arrived after several weeks but I realized I ordered the wrong inserts (my mistake). So I found the correct inserts, they were spit cheap. For a few bucks more, got a parting tool holder thrown in. We are talking 15 Kanuck bucks (probably 7.50 USD equivalent the way we are going lately LOL)
I must say it works very well. Nice controlled chips, no abnormal cutting pressure, inserts fit the pocket well, no obscure unobtanium screws. I've also got HSS & T-blade & a different, older style of carbide, it does a comparable if not better job. I think this will be my go-to parting/grooving tool now. Plus, a/p chart below, a particular insert may span many different shank sizes (both internal & external). Some of the more industrial blade holders are quite specific. Now, I haven't used a 'good' insert tool to give a firm comparison, but I'm happy with my purchase for hobby purposes.
I bought a BXA retrofit blade from Shars a couple weeks ago. It's light years ahead of the HSS blades I've used in the past.

Plus one on this recommendation...
I am a new machinist and was having a hell of a time parting with a traditional tool. I purchased a similar Shars tool with carbide bits and it made my experience with the lathe 100 times more enjoyable. Now I don't have to worry if I am going to break off the parting tool in the work
In the first step, a pre-drilled centre hole is machined to the finished dimension. The turning tool must protrude a long way for this purpose, which leads to instability. The result: fluctuating surface qualities, surface roughnesses between 5 and 10 μm and low feed rates of no more than 0.06 mm, resulting in a long machining time. Our System 110, a particularly stable tool system for challenging applications with a shaft diameter of 10 mm, provides a solution here. Whether long projections, large groove widths or large machining depths: The System 110 offers a wide array of options. A special wiper design ensures effective smoothing of the surfaces and significantly higher feed rates. Our layer of TiAIN nanoA is used to increase tool life.

Machining engineers often use two or more tools to groove different flutes on the outside diameter: Separate tools are often used for pre-grooving and finishing. The problem? Each tool change cycle leads to dimensional fluctuations and increases the machining time. The 128 Grooving System offers a more economical solution. Blanks are available in widths of 10 to 28 mm. The entire contour, including chamfers and transition radii, is ground onto these blanks. This allows the user to machine the entire contour with just one tool. A Gühring coating tailored to the application enhances the performance further. The tool holders are particularly sturdy thanks to their clamping screw with M6 thread and a V-shaped contact surface.
The outside diameter of the drive shaft needs to be serrated. Milling this profile requires precision and a high surface finish. In addition, the machining time should be reduced, for example by increasing the number of teeth, which is difficult in confined spaces. System 305 is perfect for this. Due to its compact design, this special tool is particularly stable. Despite limited space, four indexable inserts whose special geometry is adapted to the component requirements can be mounted on a milling body with an internal coolant supply. Thanks to three usable cutting edges, they offer good cost-effectiveness and their FIRE coating has proven successful in steel machining.
When creating a keyway, the grooving tool does not rotate, but is pushed into the hole. A long protruding tool is required here, too, but this is often unstable and leads to vibrations. In addition, a burr forms when the tool emerges, which then has to be removed manually. System 128 is also the solution here. The contour of the flute has already been ground into the cutting insert. The sturdy special basic body features innovative cooling channel technology to optimally supply the cutting edge with coolant. The result: Burr development is minimised and tool life is increased.

At the end of a turning operation, the parting off of the component usually occurs. Process-reliable chip removal is one of the key points here. If chips jam in the flute, this can lead to tool breakage. System 222 is the solution here. The new parting off plate for steel materials impresses with its combination of effective chip breaker, coordinated carbide and a FIRE coating. The chip breaker ensures safe chip constriction, meaning the chips run off without jamming. The tool holders with optimally arranged coolant holes support chip removal.
