uxcell1/8" 3/16" 1/4" 5/16" Chucking Reamer H7 Accuracy High Speed Steel Lathe Machine Reamer 6 Straight Flutes Round Shank Milling Cutter Tool Reamer Set for Bore Machining 4pcs

Liked quality for a good price

I’ve only used one so far and it did the job ok

I didn't realize they are mini reamers

These are good reamers that come very close to the stated size. They all measure just a few thousands under size but for most of the work I do they are fine. Overall they are nice and sharp with clean and straight flutes. These all have laser markings of the size on the shanks so they are easy to identify. So, these are good for making small precise holes and the price for all four is very reasonable.

Tools looked great, used the .125 diameter one. Worked fine

this was a gift, the person receiving to was very pleased thank you

Very pleased with the product. thank you!

One of the flutes had a ding in it so much so that it bent the flute, so that one was unusable, I also looked at the edges under magnification and these reamers had uneven grinding on them to the point many of the flutes had the grind taper off or on some part of the edge it just wasn't ground at all. Compared to my more expensive reamers which have a perfectly straight and even grind on all the flutes. So these just aren't useful for me and clearly aren't within their stated H7 spec.Maybe you'll get a better set than mine, but this was my experience.

If you're expecting to ream thick metal with cheap reamers then you deserve what you get. These are perfect for reaming out 3D printed parts, which is why I purchased them. It is true they are shipped loose but under a microscope (you do have one right?) there were no issues. I just 3D printed a stand for them...and used them to ream the holes to fit! No issues. I suspect these would be fine for annealed copper and aluminum but I have not tried it.

These came in a plastic bag no protective covers on the cutting edges haven’t tried them yet also measure over size by half a thousand’s
