What is an Abrasive Blade?

A bonded abrasive wheel is a self-sharpening grinding (or cutting) tool composed of hard abrasive grains held together by a bonding material.

Husqvarna abrasive products are available in a variety of shapes, sizes and specifications for a wide range of cutting, grinding and finishing applications.

Abrasive Grain Types

• Aluminum Oxide is a tough, wedge-shaped, man-made ceramic powder used for cutting or grinding.
• Silicon Carbide is a hard, sharp, man-made ceramic powder used for cutting or grinding concrete, masonry, stone and similar materials.

Bonding Material

The bond in most Husqvarna abrasives is a synthetic resin which holds the wheel together and supports the exposed surface grains.

Reinforcing Material

Woven fiberglass cloth reinforcing provides added strength and flexibility. One or more layers of reinforcing are used, depending on the application.

Wheel Types

Wheel types are identified with a numeric code in the specifications (see image on right). Wheel Types

Abrasive grain grit sizes are included in the specifications for Target raised hub wheels, cup wheels, grinding stones and fiber sanding discs. Grit Sizes

The hardness of an abrasive wheel represents the bond strength of the wheel and the wheel's ability to hold on to abrasive grains under cutting or grinding loads. Bond Hardness
