Manufactured with premium grade aluminium oxide grain giving superior durability and flexibility. Aluminium oxide flap wheels are ideal for hard to reach areas where a wheel or disc will not fit and can be used for a wide variety of applications including blending and finishing. Wheels are designed with a 3mm or 6mm steel shank which runs through the wheel creating better balance, a reduction of chatter, and reduced operator fatigue. They also permit quick changes on air tools when using other abrasive products.
