2×72インチ PRIZMA 構造粒 アルミナ酸化物 X-wgt サンディングベルト 4個パック (PRO)

I was blown away by how long these belts held their edge on a batch of stainless handles—the X-wgt backing really does stop belt wandering. The PRIZMA structured grain cut consistently from the first pass to the last, and I never had to swap belts mid-project.

These belts cut through hardened steel way faster than the generic ones I was using before, and the structured grain doesn't load up with metal. Still cutting sharp after a full day of grinding.

I've been using these on my 2x72 grinder for knife making and they cut through steel much faster than the cheap belts I had before. The X-wgt backing holds up well under pressure without tearing, and they seem to last a good while.
