3M Fibre Disc 1187C Cubitron III 125x22mm 36+ Slotted (25-Pack) 7100310794

For aggressive stock removal and weld grinding, this 3M fibre disc stands apart through its precision-shaped ceramic grain that continuously fractures to expose sharp cutting edges. The slotted design reduces loading on soft metals while the stiff fibre backing delivers controlled grinding action on angle grinders.

Highlights

• Cubitron III precision-shaped grain for fast, cool cutting
• Ceramic aluminum oxide abrasive for long life
• Slotted disc reduces loading and heat build-up
• 125 mm diameter with 22 mm bore fits standard angle grinders
• Coarse 36+ grit for heavy material removal
• Resin bonding on vulcanized fibre backing
• Pack of 25 discs

In daily use

Mount the disc on a 125 mm angle grinder and tackle weld seams, bevels, and edge chamfering on stainless steel, mild steel, high nickel alloys, and cast iron. The precision-shaped grains stay sharp longer, reducing the need for frequent disc changes and maintaining consistent cut rates throughout the disc's life. The slotted design helps prevent clogging when working with softer materials, while the fibre backing provides the rigidity needed for flat, controlled grinding.
