2 X 72 吋 鋁氧化物 J Flex 棉質精加工皮帶

I used these on my stainless knife blades and the closed coat aluminum oxide cut way faster than the generic belts I had before. The cotton backing is soft enough to follow contours without gouging the metal.

The J Flex backing on these 2x72 belts is surprisingly supple, so they hug curved metal surfaces without any stiffness. I used one for a full hour on stainless and the closed coat aluminum oxide stayed sharp the whole time, no glazing or excessive wear.

The cotton backing on these belts is exactly why I grabbed them, and it makes a huge difference on metal—no tearing or shredding even under pressure. The closed coat aluminum oxide keeps the grit cutting smoothly for a long time, so I’m not swapping belts every few minutes.
