10pcs HSS H8 Reamer Set Straight Shank Chucking Machine Reamer Set H8 Milling Cutter Tool Set for Lathe Chucking Machine Reamer 3/4/5/6/7/8/9/10/11/12mm

Not the best quality reamers, but certainly will do the job.

Poor quality but usable, Chinese junk

Inexpensive metric reamers. Did the job great in my 9x20 lathe. Sharp, accurate and stout (I ran the 10mm one WAY too fast and it took it like a champ). These would be absolutely perfect for someone just starting out on an HF/Seig/Grizzly mini-lathe or mini-mill. Amazing price point, good quality and you get a LOT for your money. I'll add some pictures shortly of them in action on my LMS HiTorque.If any of these wear out or break, i'll absolutely buy another for this price. US Domestically, a single chucking reamer will be more than the $25 price point.

The chucking reamers work. They make mostly round holes of about the right diameter.But not perfectly smooth holes, because they were shipped with the reamers banging against each other in a plastic envelope. The cutting edges were somewhat damaged by the contact with the other reamers.

I use them to clean holes on 3d prints and to make sure they end up with the correct diameter.

Shipped in a plastic envelope inside a plastic bag with no separation between reamers. Cutting edges dinged and not sharpened properly. These need to be separated or individually protected in order to be kept sharp.

I realize these are inexpensive reamers. I failed to realize that company with the ability to make them would know they should be packed separately. Even simple little plastic sleeves would have done job. As it is the abrading between the reamer blades has left several of them with damage to the blades.It seems like 4 cents worth of plastic bags would have been a good investment to avoid a full replacement of the set. even wrapping in paper would have done the job.

First off this is my second set and were sent in a torn and broken manufactures package as the photo shows. The first set came in the same ripped package and one reamer was missing, I sent them back for a replacement set. Amazon is wonderful with making things right and in short order.These are a very inexpensive set of reamers that will clean up a drilled hole to a more or less true size. Good for home use but are not accurate enough for production use.As you can see in the photos of the reamer heads, they are not well machined, the reamer flutes have a wavy rear edge but the front edge is straight and cuts well. Some of the reamers are a shade over the stated size and some are just a shade under. For example the 12mm reamer is 11.95mm the 9mm reamer is 9.08mm.So depending on what you plan to use these these for, you may or may not be happy with the results. BUT, for the very low price these do a okay job.
