Thin Metal Cut-Off Wheels 4" & 5" (50 pcs) — Ultra-Thin 0.8mm Cutting Discs for Angle Grinders
Thick, slow-cutting discs waste material, generate excess heat, and leave ragged edges that need grinding down afterward. If you're cutting metal pipe, rebar, sheet steel, or stainless for automotive, fabrication, or construction work, the disc you choose directly affects your cut quality and job speed. These 0.8mm thin cut-off wheels are built for DIYers and tradespeople who need clean, fast cuts without the frustration.
Each pack contains 50 reinforced fiberglass abrasive cutting discs in your choice of 4 inch (100mm) or 5 inch (125mm) diameter, both with a standard 7/8" (22.2mm) arbor. The ultra-thin 0.8mm profile reduces kerf width and heat buildup, while the reinforced fiberglass mesh backing resists shattering under load. Rated to 10,000 RPM (4") and 13,300 RPM (5").
Use these discs for cutting mild steel and stainless steel tubing in metal fabrication shops, trimming rebar and angle iron on construction sites, automotive exhaust and body panel cutting, and general-purpose metal cutting with a 4" or 5" angle grinder. The 50-piece bulk pack keeps you stocked through extended projects without mid-job supply runs.
Compatible with: 4" Angle Grinders · 4.5" Angle Grinders · 5" Angle Grinders · 7/8" (22.2mm) Arbor · Corded & Cordless Grinders
Not suitable for masonry, tile, wood, or plastic. Always inspect discs for cracks before use. Never exceed the rated RPM. Use with grinder guard installed.
✅ Key Features of These Thin Metal Cut-Off Wheels
- Ultra-Thin 0.8mm Profile: Narrower kerf means less material removed, less heat generated, and faster cutting speed compared to standard 1mm+ discs — cleaner cuts with less cleanup.
- Reinforced Fiberglass Backing: Double-layer fiberglass mesh reinforcement resists disc shattering and lateral flex under load, maintaining structural integrity at full RPM.
- Cuts Metal & Stainless Steel: Abrasive compound formulated for ferrous metals including mild steel, stainless steel, iron pipe, rebar, and sheet metal — no disc swapping between materials.
- 50-Piece Bulk Value Pack: Stock up for extended projects or job site use. Bulk quantity reduces per-disc cost and eliminates mid-project supply interruptions.
- Standard 7/8" Arbor Fit: Universal 22.2mm arbor fits the vast majority of 4" and 5" angle grinders without adapters — swap in and get cutting immediately.
- Two Size Options: Choose 4 inch (100mm) for tighter access and lighter grinders, or 5 inch (125mm) for deeper cuts and higher-capacity grinders — same ultra-thin spec in both.

❓ Frequently Asked Questions
What materials can these cut-off wheels cut?
These thin cut-off wheels are designed for metal and stainless steel, including mild steel, iron pipe, rebar, and sheet metal. They are not intended for masonry, tile, wood, or plastic.
What is the maximum RPM for these cutting discs?
The 4-inch discs are rated to 10,000 RPM and the 5-inch discs to 13,300 RPM. Never exceed the rated RPM of the disc or your grinder, whichever is lower.
What arbor size do these wheels use?
Both sizes use a standard 7/8" (22.2mm) arbor, compatible with most angle grinders on the market. No adapter is required for standard grinders.
How thick are these cut-off wheels?
The discs are 0.8mm (approximately 1/32") thick — an ultra-thin profile that minimizes material loss and heat buildup for faster, cleaner cuts compared to standard 1mm+ discs.
Are these wheels compatible with my angle grinder?
Yes, as long as your grinder accepts a 7/8" (22.2mm) arbor and the disc diameter matches your grinder's guard size. The 4-inch disc fits 4" and 4.5" grinders; the 5-inch disc fits 5" grinders.
How do I get the cleanest cut with these discs?
Hold the disc at 90° to the workpiece and apply steady, even pressure — let the wheel do the cutting. Avoid side pressure or twisting, which can cause disc breakage. Always use the grinder's guard and keep bystanders clear of the cutting plane.
What safety gear should I use with cut-off wheels?
Always wear ANSI-rated safety glasses or a face shield, cut-resistant gloves, and hearing protection. Ensure the grinder guard is properly installed and inspect each disc for cracks or chips before use. Discard any damaged disc immediately.
