Indexable Lathe Turning Tool 21Pcs Kit 3/8'' 10mm Shank 7Pcs Metal Lathe Tools Holder Set with 14Pcs Turning Inserts for Turning Grooving Threading Boring Carbide Inserts Carbide Turning Tool

I have an old, clapped-out lathe that gets used at random times, mostly when a project goes off the rails and I need to make, modify or repair something in a HURRY. Because of this, I never know what I'll be making or what material I'll be using. Last time I fired up the lathe, I was modifying a brass hose barb to replace a broken fitting on a plastic car radiator. This was on a Sunday afternoon and I needed that hose barb 5 minutes ago. I bought this kit because I'm not the best at grinding HSS tools for the lathe. I wanted something I could throw on the lathe and get to work, rather than take 3 or 4 attempts to get tool geometry right, hone the edge, etc. This set is inexpensive, uses commonly available inserts, and has several different tool formats. I figured I could buy an entry-level set of tools and then upgrade if/when I needed to. So far, I haven't needed to. I've used these tools on a couple of different projects and so far they've been fine. I've turned brass and mild steel, but also used them to reduce the outer diameter of a tool steel spark plug socket for use in a motorcycle engine. The tool left a pretty good surface finish even though my lathe is worn out and tends to fight me a bit, and it cut the relatively hard steel without a single complaint. If you need an entry level set of carbide lathe tools for next to nothing, you could do a lot worse than this set. The inserts have survived some interrupted cuts and other mild abuse that I for sure thought would have done some damage. So far, I haven't had to switch out a single insert. I'm impressed. This is a perfect kit for a home machinist on a shoestring budget (like me), or for someone who doesn't want to spend top dollar while dipping their toes into the machining world. I'll still keep HSS tools around for specific uses (form tools, cutting plastic or softer metals, etc.) but these will probably do the lion's share of the work in the future.

Very affordable carbide metal lathe tools. As a hobbyist, I'm not a day in day out machinist but I can talk from my past experiences...as a retired shop teacher. My last machining work was high school 40 + years ago and one class in college over 30 years ago. Cutting tools at the time were high speed steel. Carbine cutters were on the horizon... My images show a chess set Rook finished as a keychain. The second image is of the new tool at work in the tool holder and the blue carbide tool that came with my mini lathe. The quality of cut is night and day, when comparing the two cutters. I found the ease of cutting to be much improved and very smooth. I am not impressed with the Tork (star) head screw driver bits that came with the tools. Either they have stripped out or the tiny screw that holds in the carbide cutter. I did have one cutter loosen up during my run today. That was easy to re-tighten the cutting bit. I will purchase a new Tork head screwdriver for future use. I'm happy with my purchase!

Im very satisfied with the tools and delivery! GOOD JOB!

Does the job on my 9x20 mini lathe. Be sure and order extra inserts when you order the kit though Good fit for the 9x20 lathe. Helps improve accuracy because you can replace a broken insert without removing the holder from the tool post. Seems to be durable so far.

Looking for an inexpensive set to start with ...these are the ones! One .007 shim and off we went. The cutters are made to HOG material off yet preformed great! I am very happy with this set!

Los porta insertos son de buena calidad se ven bien y cumplen con las especificaciones, pero los insertos que incluye son de regular calidad y no todos entran en el porta insertos correctamente verifique colocando insertos comprados aparte y cazan perfectamente, si recomiendo el producto teniendo en cuenta que hay que colocar insertos de buena calidad. Si recomiendo el producto.

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.

This is a nice set of carbide indexable turning tools. They are well made and they did perform very well turning steel parts on my metal lathe. They really are 12mm tools, 1/2" is only an approximation.

I got these lathe tools to try on my mini metal lathe. I am by no means an expert when it comes to machining but I found these cutters very easy to use and they left a great finish on aluminum and mild steel. The size of the cutters is nice for removing material to bring a part down to your desired diameter, they are sharp and because they are round you can rotate to get a new sharp edge. It’s important to make certain the cutters are tightly installed to avoid any chatter, but I had no issues with them working loose. I did not try anything with an interrupted cut so this could be a problem in that case. Overall the value for the money is excellent, the inserts alone normally cost what you pay for this set. This is a nice tool to add if you are a hobby machinist.

Great service, great product, will definitely buy from again and recommend to others.
