Description
The 3M 787C is a fibre disc with precision-shaped ceramic grain and grinding aid. 3M designs it for very fast cutting on difficult metals, in particular stainless steel and nickel-rich alloys.
Specifications
- Mineral: 3M precision-shaped ceramic grain, with grinding aid.
- Backing: firm fibre, resin bond.
- Grits: P36, P60, P80 and P120.
- Diameters: 50 and 75 mm (type R), 100 mm (16 mm bore), 115, 125 and 180 mm (22 mm bore).
For stainless steel and nickel alloys
These metals are difficult to grind: they conduct heat poorly, so it stays concentrated in the cutting zone. The disc heats up, dulls and discolours the part. The grinding aid of the 787C lowers the cutting temperature; the ceramic grain keeps cutting instead of rubbing.
3M highlights the cost per part: a tougher abrasive lets you work more parts than with conventional discs.
Applications
Grinding welds on stainless steel, chamfering, stock removal on heat-resistant alloys, heavy grinding in boilermaking and pipework.
Using it well
Mount the disc on a backing pad of the right diameter. Keep an angle of 15 to 30 degrees and firm pressure. On stainless steel, keep the disc moving so as not to concentrate heat. The small type R diameters fit a die grinder with a Roloc disc holder.
