Zirconia Alumina Cutting Wheel for Angle Grinders

The United Abrasives-Sait 20125 is a depressed-centre cutting wheel built with zirconia alumina abrasive grain. It fits angle grinders equipped with a 5/8-11 threaded arbor. Metal fabricators and maintenance crews use it for straight cuts on steel and stainless profiles where a durable, fast-cutting wheel is required.

Consistent Cut Rate Through Thick Sections

Zirconia alumina fractures in a controlled way to expose fresh cutting edges during prolonged contact with the workpiece. This self-sharpening action keeps the wheel biting through heavy wall tube, plate and bar stock without the rapid dulling seen on conventional aluminium oxide wheels in the same application.

Low Vibration and Reduced Operator Fatigue

The depressed-centre design centres the cutting plane close to the grinder spindle, limiting side load and run-out during normal use. Less vibration reaches the tool handle, so the operator can maintain a steady feed rate for longer periods. Heat builds more slowly in the workpiece, lowering the risk of discolouration on heat-sensitive alloys.

Questions about this item

How much heat does the 20125 cutting wheel generate during extended use?

Zirconia alumina abrasive runs cooler than standard wheels, reducing heat buildup on the workpiece and the wheel itself during long cutting sessions.

What grinder spindle does the 5/8-11 arbor require?

The wheel fits any angle grinder or pneumatic tool with a standard 5/8-11 threaded spindle, no adapter needed.

Will the 20125 wheel work on older grinders that run at lower RPM?

Yes, the zirconia alumina grain cuts efficiently across a wide speed range, so it performs well on older tools that cannot reach modern maximum RPM ratings.
