The rotational burst performance of the Zhibiao350 cut‑off wheel

Today we test the rotational burst performance of the Zhibiao350 cut-off wheel.

Its marked critical burst speed is 6548 RPM.

We keep increasing the speed. It holds steady, and burst only at 10577 RPM.

You can do the math. Compared with the marked standard speed, it delivers a substantial safety margin.

This speed difference is the safety buffer reserved for your practical-site operation.

The quality of mesh backing, resin and bonding process are all reflected in the burst speed.

Important note: This is a laboratory-only extreme test.

Never exceed the speed marked on the nameplate during actual construction work.
