Need a coarse sanding disc to use on carbon steel? Opt for this one from 3M. It has a grit size of P36 to work efficiently on fabrication tasks such as chamfering and weld removal. Made with a precision-shaped grain, it cuts easily through metal surfaces, so less grinding pressure is needed. The durable fibre backing and resin bonding reduce wear and tears when you're working on mild steel, aluminium and nickel alloy materials.

• Uses strong ceramic minerals to work effectively on metals
• Closed-coat construction with densely packed grains for a more forceful cutting action
• Punched with a centre hole and slots for a universal fit on clamp-fixing grinders

• Ship and boat building
• Automotive repair and car detailing
• Metal fabrication

Using the 3M™ 782C 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 for edge chamfering bevelling, deburring and weld removal on mostly carbon steel.

An abrasive disc with a coarse grade of grit is handy for initial preparation work such as removing excess material. A disc with a fine grade of grit is useful for finishing tasks, such as smoothing out surface imperfections ready for painting.

Using 3M™ precision-shaped grain technology to offer a higher initial and durability to outlast conventional ceramic fibre discs. The grit wears evenly and with the abrasive staying cooler and sharper, the PSG abrasive lasts significantly longer than conventional ceramic discs. These discs will help to step up production with an improved output on both light and heavy stock removal.

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

The 3M™ 782C 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 782C disc is for use on carbon steel, the 787C is used for stainless steel and other non-ferrous alloys such as aluminium and titanium (Sold at RS).

These abrasive discs are desinged for use 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.
