This flap disc is an abrasive finishing product designed for medium to high unit-pressure grinding on metals. It combines aluminium oxide mineral with a specialised ceramic-shaped grain to deliver consistent cutting on carbon steel, stainless steel and nickel/chromium alloys. Supplied in packs, it is intended for use on guarded angle grinders in industrial settings where controlled material removal and weld blending are required.

Features & Benefits

• 40 grit enables aggressive stock removal and Rapid metal shaping
• Resin bond offers Durable abrasive life under heavy load
• Polyester backing with fibreglass hub gives stable support during use
• Centre hole 22.23mm ensures secure mounting on compatible grinders
• Available in Type27 and Type29 forms for varied grinding angles

Applications

• Suitable for weld removal and preparation on steel structures
• Ideal for deburring and edge chamfering in fabrication
• Used for surface blending on stainless components in production
• Can be used for metal preparation prior to coating or painting
• Suitable for repetitive grinding tasks in mechanical workshops

What substrate composition is the abrasive suited to?

The mineral mix combines aluminium oxide with a precision-shaped ceramic grain formulation, optimised for carbon steel, stainless steel and nickel/chromium-based alloys.

How should packs be stored to maintain performance?

Retain items in their original packaging and store at about 16°C to 26°C with 35 to 50% relative humidity

follow first-in first-out rotation to reduce shelf-life loss.
