3M 769F Ceramic Type 27 and Type 29, 150 mm, 80 Grade, 20 Grit 20 Per Pack

This flap disc is an abrasive tool designed to remove material and blend welds on metal components within industrial environments. It combines a blend of aluminium oxide and a ceramic precision-shaped grain to deliver steady cutting action under medium to high unit-pressure use. The product suits both fixed and portable grinding equipment and is supplied in packs for repetitive workshop operations.

• Aluminium oxide and ceramic PSG blend delivers consistent stock removal
• Resin-bond construction maintains abrasive integrity during heat exposure
• Polyester Y-weight backing yields controlled flexibility and contact
• Fibreglass hub support reduces disc distortion at higher speeds
• Centre hole 22.23mm compatibility simplifies arbor mounting
• Available in 80 grit for higher material removal rates

• Suitable for weld blending on carbon steel and stainless steel
• Ideal for deburring and edge breaking on fabricated parts
• Used for surface preparation of nickel/chromium alloys prior to finishing
• Can be used with angle grinders for heavy-duty metalworking tasks
• Suitable for repetitive grinding in automation and mechanical workshops

It is intended for carbon steel, stainless steel and nickel/chromium-based alloys where medium to high-pressure grinding is required.

Keep in its original packaging at 16°C to 26°C and 35 to 50% relative humidity using a first-in, first-out rotation to avoid shortened shelf life.

Use only on guarded tools and do not trim the fibreglass support plate to prevent injury
