Abrasive Fibre Disc 3M Cubitron II 982C 115x22 mm, Grit 36+, Pack of 25

3M Cubitron II 982C abrasive fibre discs, 115 x 22 mm, grit 36+ in a pack of 25 are engineered for high-performance metalworking with angle grinders. The discs use precision-shaped ceramic abrasive grains that deliver fast material removal, consistent cutting and grinding performance, and improved life compared with conventional abrasives. Designed for tasks such as weld removal, surface preparation, deburring and heavy stock removal, these fibre discs maintain cutting speed and resist glazing under heavy load.

Advantages

The precision-shaped ceramic mineral provides rapid cut rates and consistent aggressiveness throughout the life of the disc. The fibre backing supports pressure and heat distribution for stable grinding while helping to extend disc life. These discs offer reduced heat generation on the workpiece and improved profile retention, which can lower the number of passes required. The 115 mm diameter and 22 mm centre hole fit standard angle grinders, and the pack quantity of 25 ensures ready supply for continuous workflows.

Suitable for

• Metal fabrication and structural steel preparation
• Weld removal and blending
• Surface cleaning and rust removal before painting
• Deburring and edge breaking on steel components
• Heavy stock removal where fast cutting is required

Key specifications

• Disc diameter: 115 mm
• Centre hole: 22 mm
• Abrasion type: precision-shaped ceramic abrasive
• Grit: 36+
• Backing: fibre disc construction for pressure resistance
• Pack quantity: 25 discs
• Intended tool: angle grinder

How to use

Mount the disc securely on a compatible angle grinder with a matching 22 mm arbor. Use appropriate guards and follow the tool manufacturer’s instructions for safe mounting and operation. Select a suitable speed and apply consistent light-to-moderate pressure, allowing the abrasive to cut without excessive force. Maintain a stable grinding angle and keep the disc moving across the workpiece to avoid gouging and to distribute wear evenly. Replace the disc when cutting performance drops or the disc shows signs of damage.

Recommendations

For best results, wear appropriate personal protective equipment including eye, ear and respiratory protection. Use the 3M Cubitron II 982C discs on clean, dry surfaces and avoid excessive side load. Match grit 36+ to aggressive stock removal tasks; switch to finer grits for finishing passes. Store discs flat in a dry environment away from extreme temperatures to preserve performance.
