This flap disc is an abrasive finishing product designed for medium to high unit-pressure grinding on carbon steel, stainless steel and nickel/chromium alloys in industrial settings. It is intended for use on guarded powered tools and offers a balance of material removal and surface refinement for fabrication and maintenance tasks.

Features & Benefits

• Aluminium oxide and PSG mineral blend increases cut rate and life
• Resin bond maintains abrasive integrity under heavy use
• Polyester Y-weight backing provides stable wheel support
• Fibreglass hub construction enhances rotational stability
• Available in multiple grades to suit finishing needs

Applications

• Suitable for weld blending on steel fabrications
• Ideal for surface preparation before coating or bonding
• Used for burr removal on machined components
• Can be used for deburring and finishing stainless assemblies
• Suitable for repetitive grinding in production lines

What backing and hub construction does it use?

It uses a polyester Y-weight backing together with a fibreglass hub to deliver a stable support structure and improved wheel rigidity during abrasive operations.

Which abrasive minerals are incorporated and why?

A blend of aluminium oxide and a precision-shaped ceramic grain is used to balance material removal with abrasive longevity across mixed metals.

How should the product be stored to preserve performance?

Store in original packaging at 16°C to 26°C and 35 to 50% relative humidity on a first-in, first-out basis

exposure to high heat or humidity may reduce useful life.
