The is a box of abrasive discs built for real stock removal — no fluff, just performance you can feel. These aren’t your typical soft paper discs; the zirconia grain cuts aggressive and keeps cutting longer than economy pads.

Grab a full 100‑pack and you’ve got a stash of 100 mm discs with a 16 mm arbor hole that fit most 4 ½‑inch grinders and sanders — and because they’re designed for metal and tough surfaces, they won’t waffle out under pressure. Each piece is made to tear through welds, blend edges, and scuff up surfaces fast without shredding like cheaper discs do.

Key Features:

• Zirconia Alumina Grit - bites hard into metal so you can grind faster and spend less time scraping.
• Tough Fibre Backing - adds strength so discs don’t fold or rip on you in the middle of a job.
• 100 Pc Box - plenty of discs so you can get through a big project without running out.
• 100 mm Diameter - fits standard 4 ½‑inch sanders and grinders you already have on the rack.
• 36 Grit Coarseness - aggressive cut for heavy stock removal and weld prep.

Applications

On the job site or in the shop, this zirconia fiber disc shines where you need blunt force sanding and grinding — think removing rust, shaping welds, cleaning up castings, or prepping metal surfaces before paint. It doesn’t just work on steel; in practice you’ll find it handy on iron, stainless, and even some wood applications when you need to strip fast.

Why Choose This Model

Here’s the thing — there’s plenty of cheap discs out there that fall apart or load up with gunk by the second pass. This 100 piece zirconia pack gives you the breathing room to keep working without babysitting your abrasives, and that matters a lot when you’ve got sheets of metal to knock back or welds to flush out.

Technical Specifications Explained

• Disc Diameter - 100 mm means it fits most grinders and disc sanders you see in professional kits.
• Bore Size - 16 mm center hole ensures it seats properly on common 4 ½‑inch tools.
• Grit Size - 36 grit is coarse, so you’re cutting metal and material quickly rather than polishing.
• Material - Zirconia alumina grain stays sharp under heat and stress — cuts longer than cheap aluminum oxide discs.
• Pack Quantity - 100 pieces keeps you stocked up and saves you runs to the store.
