This high-performance sanding disc from 3M is made with a precision-shaped grain that wears evenly. It has a grinding aid incorporated to keep the disc cool, prolong its working life and enable working on heat-sensitive alloys without warping the workpiece. The grit is strongly resin-bonded to the stiff fibre backing to resist tearing. This wheel is an ideal choice for applications such as removing steel welds, edge chamfering and machining grooves. Its reliable cutting effectiveness minimises the grinding pressure needed, reducing user fatigue.

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.

This disc is suitable for grinding stainless steel and other non-ferrous alloys such as aluminium and titanium.

No, using this disc to grind wood isn't recommended.

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.

A. 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).

A. No, these are not recommended to be used on wood, just the metals.
