If you are working on a large project which requires heavy abrasive work, whether it’s grinding down heavy welds, aggressively removing stock, or preparing a surface for the next step – you need an abrasive disc that truly performs. Some abrasives can feel like you’re fighting the material, which in turn causes slow progress and quick wear.
To help you avoid this situation, at Engweld we are proud to offer a wide range of 3M fibre discs. These fibre discs aren't just ordinary sanding discs; they're high performing abrasives designed by 3M to cut faster, last longer, and make the toughest material removal jobs feel smoother and more efficient. 3M is a global manufacturer in the world of abrasives, constantly ahead of what is possible. Their fibre discs are a prime example, they are engineered with advanced grain technologies and with durable backings.
Fibre discs are a go-to for heavy-duty grinding and surface preparation thanks to their robust construction: a strong, rigid fibre backing coated with a layer of abrasive grain. This design allows for aggressive material removal, making them perfect for tasks such as weld removal, bevelling, cleaning up scale, and general stock reduction. What sets 3M fibre discs apart is their proprietary technology, which ensures:
We've carefully selected the leading 3M fibre disc lines to meet the demanding needs of our professional customers:
These discs are made with the 3M’s Precision Shaped Grain (PSG) technology. This revolutionary ceramic abrasive is geometrically designed to fracture and form incredible sharp points that slice through metal rather than gouging. This results in unprecedented cut rates and enhances long disc life, especially on challenging materials like stainless steel, mild steel, carbon steel, and exotic alloys.
Some of the main products in this range of premium discs are the 3M Cubitron 3 1182C, the 3M Cubitron 3 1187C and the 3M 982Cx Cubitron II. These three 3M Fibre discs are good if you are looking for high performance fibre discs from one of the most renowned manufacturers in the world of abrasives. Paired with a proper backing pad, you’ll have the best combination possible for your next project.
The 3M Fibre Disc 787C and 782C also features 3M’s Precision Shaped Grain (PSG) technology and delivers excellent durability and a fast cut rate. This makes them a reliable performer for a wide range of medium-pressure grinding and finishing applications.
Find a range of 3M 787C with the 3M Fibre Disc 787C 125mm X 22 P60G Grit for instance and from the 3M 782C range, the 3M 782C 115mm Sanding Disc 60G. It’s a versatile option for general metal fabrication and maintenance, offering a great balance of performance and value for everyday metal fabrications tasks.
When selecting a fibre disc, the type of abrasive grain is paramount, defining its cutting aggression, durability, and ideal application.
Aloxite Fibre Discs, primarily made with Aluminium Oxide, are the most common and economical choice. They are a good all-rounder for general purpose grinding on mild steel, iron, and non-ferrous metals, offering consistent performance for tasks like blending and light stock removal.
Stepping up in performance, Zirconia Fibre Discs feature a tougher, more durable abrasive grain that fractures to maintain sharp edges. These are excellent for medium to heavy stock removal on mild steel, carbon steel, and some stainless steel applications, providing a longer lifespan and faster cut than aluminium oxide.
For the most demanding jobs, Ceramic Fibre Discs stand out, often utilising Precision Shaped Grain (PSG) technology. These highly engineered ceramic grains are exceptionally hard and sharp, designed to self-sharpen and cut aggressively for extended periods, making them the superior choice for high-pressure applications, heavy weld grinding, and working with hard metals like stainless steel, exotic alloys, and high-strength steels.
All fibre discs require a Backing Pad to function correctly on your angle grinder. These pads provide the necessary support and flexibility. This will ensure the disc's abrasive grains can work efficiently and safely, transferring power from the tool to the workpiece effectively. Our selection of 3M Backing Pads include 3M 115mm Red Ribbed Back Up Pad and the 3M 100mm Centre Pin Backing Pad M14.
Choosing the right 3M fibre discs with suitable backing pad is paramount to not struggle while working on grinding welds, blending and light deburring. During these parts of the project, using correctly specified equipment can save you time and money.
But fibre discs aren’t the only 3M Abrasives that we have in stock on our website. You can also find on our online shop or in our Uk Stores, 3M Cutting Discs, 3M Grinding Dics, 3M Flap Discs and 3M Non-Woven Abrasives. And because safety is a paramount when working with these types of product, we also stock 3M Dust Masks & Respirators or even 3M Versaflo to protect you against hazardous fumes and 3m Ear Protection to protect you against the noise generated during the process.
