Indexable Lathe Turning Tool 21Pcs Kit 1/2'' 12mm Shank 7 Pcs Metal Lathe Tool Holder Set with 14 Pcs Turning Inserts for Turning Grooving Threading Boring Carbide Inserts Carbide Turning Tool

Best up grade I've made in a long time

They work great

The media could not be loaded. Some of the inserts can't brake a chip to save their life, but mostly I can produce really good surface finishes with them.

These lathe turning and boring bar tools are well made and a great value. The cutting inserts have multiple cutting edges and fit perfectly in their respective tool holder. The included insert locking wrenches also have a molded thumb-and-finger tab enabling ease of changing the tool holder inserts. A well made addition to small lathe fabrication needs.

Great set of lathe tools. Have small lathe and they work wonderfully well. Very good quality for the price.

Good 👍

Works well in my mini lathe, good value for the tooling

The part that's good is the holders are accurately machined for a good fit and the inserts are very sharp. I can get a good surface finish even with .001" finishing cuts.But there are some flaws with this set that really diminish its usefulness. There are no left hand bits, so no way to turn the rim of a disc, or face toward the centerline. The external threading tool is biased so you can thread to a shoulder, but it is so much easier and safer to thread in reverse away from the chuck with the tool upside down, and for that you need a bit biased the other way.The boring bar has only .75" of relief so you can not bore any deeper without either grinding relief along the bar or angling it in the toolpost to provide the relief, which substantially increases the minimum bore size. The internal threading tool had the same issue, but of course you can't angle it because the insert is square to the axis of the bar. This insert is very small: the maximum thread pitch is about 14 TPI (1.75mm) and the minimum diameter the bar will fit inside is about 5/8" (16mm) so there is absolutely no standard nut you can thread with this tool. The external threading tool is a bit bigger and could go to 8 TPI (3mm), which is still not great.All in all, I'm disappointed in the set and expect I'll only use a couple of the tools to any extent, so what seemed like a low price is certainly not, at least for my use cases.
