Grinding Discs for Metal

Heavy-Duty Abrasive Solutions for Weld Preparation, Beveling & Surface Conditioning

At TEC Products Ltd, we supply a full range of grinding discs as part of our wider abrasives and finishing products collection, designed for aggressive stock removal, edge bevelling, weld seam grinding, and surface preparation on a variety of metals. Whether you're working with stainless steel, mild steel, cast iron, or aluminium, our grinding discs deliver powerful performance, long service life, and operator comfort in demanding industrial applications.

We partner with leading abrasive manufacturers including 3M, Norton, Pferd, Cibo, and Klingspor to bring you high-quality discs suited for both handheld angle grinders and bench-mounted grinders, available in a wide range of sizes and grit types.

Key Features:

• High Material Removal Rate: Engineered for fast, efficient grinding even on heavy welds or thick section material
• Long-Lasting Performance: Durable resin-bonded construction with reinforced fibreglass for strength and disc stability
• Application-Specific Options: Choose from discs optimised for stainless, mild steel, or non-ferrous applications
• Smooth Operation: Low vibration and controlled wear rate help reduce fatigue during extended use
• Multiple Sizes & Bore Types: Available in 100mm, 115mm, 125mm, 180mm, 230mm, and more with standard bore fittings

Applications:

• Weld seam removal
• Chamfering and beveling for prep work
• Surface grinding and finishing
• Deburring and descaling
• Fabrication, maintenance, and repair work

We Also Offer:

• Grinding discs for INOX, contaminant-free and formulated specifically for stainless steel to prevent iron pickup and post-weld staining. 
• Depressed centre and flat profile options
• Coarse to fine grit range for controlled grinding or finish prep
• Bulk packs for workshop and trade users

• Cutting discs for slitting and cutting metal, including INOX-specific options for stainless steel

Frequently Asked Questions

What is the best grinding disc for metal?

That depends on the metal and the job. For general work on mild and structural steel, a standard aluminium oxide grinding disc handles weld removal, edge shaping and surface prep well. For stainless steel, use an INOX-specific disc to avoid iron pickup and staining. For harder metals, heavy stock removal or where disc life matters, a ceramic grain disc will cut faster and last longer. For rust and paint stripping without heavy material removal, a poly strip disc is the right tool. Match the disc to the material and the task first, then the grinder.

What size grinding disc do I need?

The size you need is dictated by your angle grinder. Our range covers the standard UK sizes: 4" (100mm), 4.5" (115mm), 5" (125mm), 7" (180mm) and 9" (230mm), with a 22.23mm bore to fit standard angle grinders. Smaller discs (4.5" and 5") give you better control for detailed work, edge finishing and tight spaces. Larger discs (7" and 9") remove more material faster and reach into deeper cuts, but they're heavier to handle and need a larger grinder. Check your grinder's maximum rated disc size before buying, and never fit a disc larger than the machine is rated for.

What is the difference between a grinding disc and a flap disc?

A grinding disc is a solid, rigid disc (usually 6mm or 7mm thick) that removes material aggressively through abrasion. It's built for heavy stock removal, weld dressing and shaping. A flap disc is made of overlapping abrasive cloth flaps bonded to a backing plate. It grinds and finishes in one step, wearing gradually to expose fresh abrasive, and leaves a smoother surface than a grinding disc. Use a grinding disc for heavy material removal, and a flap disc for blending, finishing or lighter grinding where surface quality matters.

Are ceramic grinding discs better than standard ones?

Ceramic discs cut faster, run cooler and last longer than standard aluminium oxide discs, particularly on harder metals, stainless steel and heat-sensitive materials. The ceramic grain is self-sharpening: as it wears, it fractures to expose fresh cutting edges, so the disc stays aggressive throughout its life. They cost more per disc but often work out cheaper per job because you get through fewer of them. For regular work, harder materials, or where speed and disc life matter, ceramic is worth the step up.
