With its precision-shaped grain, this 3M fibre disc offers exceptional performance. An incorporated grinding aid keeps the disc cool and also improves longevity with the help of the strong resin bond between the grain and the fibre. With cutting efficiency maximised, you can grind with less pressure, meaning less fatigue for the operator. The Roloc quick-attachment system locks into place without the need for fitting tools, speeding up your workflow. Use this disc for challenging metal grinding jobs such as chamfering, machining grooves and removing steel welds, as well as metal sanding.

• Stiff fibre backing resists tearing
• Ideal for work on hard and fast-to-grind metals such as stainless steel and high-nickel alloys
• Coarse P60 grit is suitable for grinding or heavy sanding
• Maximum safe speed of 30,000rpm enables high-speed working

• Construction
• Agricultural
• Boatbuilding

Using the 3M™ 787C outperforms conventional ceramic discs. Designed to be used with a 3M™ backing pad with an angle grinder or sander. This fibre wheel is well-suited to edge chamfering, machining grooves, removing steel welds and more.

When grinding or sanding metal, appropriate protective clothing should be worn, including gloves, goggles and a dust mask. Operators should be trained and aware of any hazards associated with the material they're working on.

This disc is recommended for use with metals only and shouldn't be used on wood.

The Roloc™ system from 3M™ provides a secure attachment on heavy duty applications. It allows for Roloc discs to be quickly swapped out from one application to another in seconds. The plastic threaded button or screw is designed to easily and quickly screw on a Roloc disc pad (50 mm backing pad - 288-471).

• Cuts hard and fast to grind metals like stainless steel and high nickel alloys

The 3M™ 787C heavy-duty fibre discs are great for weld removals, grinding and blending large and small metal areas. This could occur in industries such as farm and construction, automotive, ship and boat building, metal fabrication.

The 787C is used for stainless steel and other non-ferrous alloys such as aluminium and titanium, the 782C disc is used for carbon steel (Sold at RS).

These abrasive discs are designed to be used on metals and are not recommended to be used on wood.

What safety requirements should I observe?

When grinding metal or sanding, appropriate personal protection equipment should be worn. Gloves, eye protection and even respiratory protection are essential PPE for general purpose grinding and polishing applications.

For safe operation of an angle grinder, be sure you have participated in appropriate training and are aware of all safety advice relevant to the material you are working on.
