High polish finish, perfect for what I needed them for; precise machining.

5.0 out of 5 stars Works with 1" Bearings
Reviewed in the United States on May 12, 2024
I built a 20" band saw and purchased 1" bearing and a 1" shaft. Even with freezing the shaft I couldn't get it onto the bearings. So, I purchased this. Since it isn't driving a gear, It's OK that the bearings fit a little loose (nothing a small shim made from a strip of aluminum from a pop couldn't fix). I used a grinder to cut this shaft into two 250mm lengths for the upper and lower bandsaw wheel shafts. The chrome is nice since there is 90% humidity where I live at times and I don't have to worry about it rusting.

Wood sanding wheel, used this to hold the wheel. Added some ball bearings & hooked up to an old drill that only spins one way. Works great.

4.0 out of 5 stars Cetme jig bar
Reviewed in the United States on July 8, 2024
This bar is the right diameter to bend a cetme flat around and buying it though amazon was the cheapest option. It didn't flex in the press, just worked out great.

These rails are straight and smooth just what I needed.

5.0 out of 5 stars Fine rods, very inert
Reviewed in the United States on November 9, 2023
They are exactly 10 mm in diameter. They are very round. They do not more or complain. What could possibly go wrong?

5.0 out of 5 stars Came to spec, look smooth and consistent
Reviewed in the United States on June 29, 2023
I measured these with my calipers and found them to be right on spec. They look clean and are straight from what I can see. I am not a machinist, just a hobbyist building things in my garage, so I am sure they'll be more than sufficient to my needs.
