Festool Angle Grinder Discs & Accessories

Angle grinder discs are what make the grinder earn its keep, whether you're cutting steel, dressing welds, or cleaning back rust and paint.

When you're on a deadline, the wrong disc just burns out, snatches, or leaves a mess to tidy up. Festool angle grinder discs and accessories are built for controlled cutting and consistent finish, so you get through metalwork and prep faster with fewer disc changes. Pick the disc to suit the material and the guard setup, then crack on.

What Jobs Are Angle Grinder Discs Used For?

• Cutting steel box, angle, threaded rod and fixings cleanly when you need fast trimming on site without dragging the chop saw out.
• Grinding back welds and dressing edges on fabricated brackets, gates, handrails and frames so parts fit up square and don't snag hands or cables.
• Stripping rust, paint and old coatings off metalwork before priming, welding, or bolting up, so you are not sealing dirt under the finish.
• Cleaning up burrs and sharp corners after drilling or cutting, especially on sheet and plate where a quick pass saves split gloves and torn sleeves.

Choosing the Right Angle Grinder Discs

Match the disc to the job and the grinder size, because forcing the wrong disc is how you get slow cuts, cooked edges, and kickback.

1. Cutting vs Grinding (Do not mix them up)

If you need to slice through metal, use a proper cutting disc and let it do the work. If you are flattening welds or shaping steel, use a grinding disc; side-loading a cutting disc is asking for it to shatter.

2. Disc diameter and thickness

If your grinder is set up for 115mm, stick to 115mm so the guard fits and you keep control. Thin cutting discs are for quick, clean cuts in metal; thicker grinding discs handle pressure better when you are dressing welds.

3. Material and finish

If you are working mild steel day to day, choose discs rated for metal and keep a couple spare because they disappear fast on rough cuts. If the job is prep and clean-up, go for the right abrasive or cleaning disc so you are not smearing paint and rust around instead of removing it.

Who Are These For on Site?

• Steel fixers, fabricators and welders who need reliable cutting and grinding discs that stay predictable when you are leaning into the job.
• Maintenance teams and fitters doing repairs on plant, gates, brackets and frames, where you need the right disc in the van to cut, prep, and finish in one visit.
• Groundworkers and general site teams for trimming rebar, bolts and metal edging, then cleaning up sharp edges before concrete or handover.

How Angle Grinder Discs Work for You

A grinder is only as good as the disc on the front. The disc type controls how it cuts, how much heat it builds, and how tidy the finish is.

1. Cutting discs

These are thin and designed to cut on the edge, so they get through metal fast with less drag. Keep the cut straight and let the RPM do the work, because twisting in the kerf is what causes snatching and premature wear.

2. Grinding and finishing discs

These are made to take pressure and remove material, which is what you want for weld dressing and shaping. They leave a controllable finish, so you are not chasing deep gouges with flap discs or sanding afterwards.

3. Cleaning and prep discs

These are for stripping back coatings and contamination without chewing into the base metal. They are the ones that save time on refurbs and repairs, because prep is what makes paint, primer, and welds behave.
