Innovation in Abrasives

Rex-Cut Solutions for a Superior Finish

The unique technology of cotton fibre bound The Rex-Cut allows roughing, blending, and polishing in a single operation, offering safer, quieter, and faster solutions than traditional abrasives.

Rex cut cotton discs for thinning/blending

Cotton fibre abrasive discs

The original and patented Rex-Cut discs. Their unique structure of abrasive-bonded cotton fabric layers will not load, offers a uniform, smooth finish, and allows working with heat-sensitive materials. Ideal for deburring, blending, and finishing on steel, aluminium and titanium.

Rex cut high-performance grinding wheels for welding

Grinding wheels and discs

Range of harder discs designed for aggressive cutting and grinding tasks. They include bonded abrasive technology to offer a high material removal rate (strong cutting) with reduced vibration and noise. Perfect for heavy-duty work on welds, castings, and in the metallurgical industry.

Rex cut mounted grinding wheels deburring precision

Finishing and polishing products

From mounted wheels to quick-change discs, this range focuses on smooth deburring, surface conditioning and preparation for final polishing. They are ideal for working on grooves, contours and hard-to-reach areas without altering the geometry of the workpiece.

Rex cut ceramic discs titanium inconel

Special Solutions for Aerospace and Medicine

Rex-Cut develops specific abrasives that meet the rigorous standards of critical sectors. Products designed to work with Titanium, Inconel and other aerospace materials, ensuring component integrity, high load-bearing strength, and an unsurpassed precision finish.

Why choose Rex-Cut Abrasives?

Unique cotton fibre technology

Unlike resin abrasives, the bonded cotton structure provides a cushioned sanding action. This reduces heat generation and eliminates the risk of scorching or material distortion, especially on stainless steels and sensitive alloys.

Processing time reduction

The ability to rough out and leave a finish ready for fine polishing in one step eliminates the need for multiple disc changes and tools, drastically increasing productivity and reducing labour costs.

Greater safety and comfort

The cotton binder absorbs some of the vibration and noise from the grinding process. Furthermore, the discs wear down slowly and in a controlled manner, minimising the risk of breakage and offering a quieter and safer working experience for the operator.

Uniform and consistent finish

Rex-Cut abrasives are designed to continuously expose new abrasive grain as the cotton fibre wears away. This ensures a uniform cutting action and consistent finish quality, from the first use to the end of the disc's life.

Material versatility

They offer proven solutions for efficient work on ferrous and non-ferrous metals, including carbon steel, stainless steel, titanium, aluminium, chrome, and various plastics.

FAQ – Frequently Asked Questions about Rex-Cut

What makes Rex-Cut's cotton fiber technology unique?

Rex-Cut's patented technology uses layers of Cotton cloth bonded with abrasive (silicon carbide or aluminium oxide) and a soft binder. As the abrasive wears away, the cotton fibre sloughs off, continually exposing new abrasive grit. This cushioned action drastically reduces heat build-up and prevents scorching, material distortion and metal loading on the disc.

Are Rex-Cut discs suitable for working with titanium and stainless steel?

Yes. Rex-Cut is highly recommended for Stainless steel, titanium and Inconel. Its low heat generation is critical for stainless steel, as it minimises the risk of corrosion and deformation. For titanium, they offer controlled cutting action, which maintains the integrity of the workpiece.

Can I use a Rex-Cut disc for polishing and deburring at the same time?

Yes, that is one of Rex-Cut's main advantages. Many of their discs and wheels are designed to perform tasks Roughing (material removal), blending and pre-polishing in a single operation. This significantly reduces the process steps and total work time.

What is the maximum operating speed of Rex-Cut abrasives?

The maximum operating speed (RPM) varies depending on the type and diameter of the disc or wheel. It is crucial to follow the indication printed on the label of each product and not exceed it Maximum Operating Speed (Max. RPM) for security and performance reasons. Our technical team can advise you on the optimal speed for your specific application.

Are there specific Rex-Cut products for the aerospace sector?

Yes. It's a key manufacturer in the aerospace industry and offers specific formulations (such as fine-grain aluminium oxide or silicon carbide wheels) designed to work with special alloys like titanium and chrome, where a precision finish without surface contamination is required.

What disc or wheel formats does Rex-Cut offer?

Offers a wide variety of formats to suit any tool, including:
Flat discs for angle grinders.
Wheels fitted for working on contours and hard-to-reach areas.
Cotton fibre wheels for deburring and finishing.
Quick Change quick-change discs for agile processes.

Does Rex-Cut work well with aluminium without loading the disc?

Yes, thanks to its cotton binder and porous structure, Rex-Cut abrasives are very effective on non-ferrous metals such as aluminium. Cotton fibre helps prevent loading (clogging of the disc with soft material), maintaining a clean cutting action and extending the product's lifespan.
