3M Cubitron 3 Series Fibre Disc, 115mm Disc Diameter, 80 Grit - 7100349587

This Fibre disc is an abrasive accessory for high-speed metalworking operations, designed for use with angle grinders and other powered finishing tools. It employs a ceramic abrasive for sustained material removal and is suited to tasks where controlled cutting and heat management are important.

Features & Benefits

• Re-engineered precision-shaped ceramic grain delivers Faster cutting
  Grinding aid reduces pressure and limits metal discolouration
  Stiff Fibre backing provides durability and tear resistance
  Strong resin bond supports heavy-duty grinding and weld removal
  Maintains Sharp cutting points for long-lasting abrasive life

Applications

• Suitable for weld seam removal on stainless steel and carbon steel
  Ideal for bevel preparation and edge blending in fabrication
  Used with angle grinders for robotic or manual grinding operations
  Suitable for deburring and surface preparation of non-ferrous metals
  Used in automated finishing lines for part throughput optimisation

What hole size is required for mounting on 115mm spindles?

It uses a 22mm centre hole to fit compatible flanges and backing pads.

How does the abrasive manage heat during extended use?

The mineral shape and included grinding aid promote cooler cutting and predictable wear under varied pressures.

What is the maximum safe rotational speed for these discs?

They are rated for safe operation up to 13,300 r/min.

How are they packaged for workshops and production environments?

The discs are supplied in packs of 25 to support inventory rotation and minimise changeovers.

Which backing type supports high-pressure applications?

A Fibre backing combined with a robust resin bond gives resistance to tearing during medium- to high-pressure grinding.
