uxcellChucking Reamer Set Lathe Machine Reamer Straight Flute Milling Cutter High Speed Steel H8 Tolerance (2mm 3mm 4mm 5mm 6mm 7mm 8mm 9mm 10mm) 9pcs

So I bought these to clean out brake calipers (where the pins slide).Size is good. I was pleasantly surprised with how well they worked for the purpose; function was good.The sharpness was far beyond what I expected. Durability is beyond my expectations as well. When I saw how sharp they are I expected that would wear quickly, but they have not.Recommended for light duty at least.

Accurate enough for home use. Nice and sharp.

Worked well for my purpose.

Have used several times and works. Too soon to talk on durability

These are low quality chucking reamers - on par with their price. I've purchased individual reamers from Mcmaster for critical work, but needed a full set to have on hand for general use without having to dole out a pound of flesh. They do seem to be on size, but I wouldn't trust them for critical jobs or harder materials. Most of what I'm using these on is aluminum and delrin - no problem there. Just don't expect these to be high grade and you'll be happy from a price/value perspective.

Great for small engine valve guide clearance

Haven’t used yet, looks like they are exceptionally well made, but I already smell the cheap lubricant and not impressed at how they were packaged. We will see

Exactly what I was wanting !! The tool to fix my broken valve guide !! And I got it the next day !! Great quality and Seller !! I would recommend this product to family and friends !! 💯
