FOXBC 5-Inch Metal Cut-Off Discs — 0.045 in Thin Kerf, 7/8 in Arbor (25-Pack)

Reviews

1. R Ruben Salais 1/5

   Broke during my use

   I tried these on a small project and some wheels fractured off the grinder. Not reliable for my setup.

   Five-inch discs reach tight areas

   I like the 5" size because it gets deeper into awkward spots and seems to last. They won't fit some guards without removing or swapping the guard, so be aware of that. No breakage so far; they cut quickly and hold together well. Recommended for those who need extra reach.

   Thin-kerf 5-inch cut-off discs

   This 25-pack is handy for fabrication and shop work. The 5" x 0.045" x 7/8" Type 1 discs are made for angle grinders and handle steel, stainless, cast iron and sheet metal. The thin kerf removes less material and reduces burrs, making straight cuts faster. The aluminum oxide blend is aggressive for rapid removal, and two fiberglass layers add strength for handheld cutting. Rated to 12,200 RPM and fitting a 7/8" arbor, they are a practical bulk supply.

   Simple, effective cut-off discs

   Performs as expected.

5. H Harry M. 5/5

   Sturdy discs for solid steel

   Used these to slice through 1-1/4" solid steel; wear was minimal after several cuts. The discs stayed stable and cut at a good pace. The slightly wider kerf compared with ultra-thin blades removes more material but seems to help longevity. Good choice when durability matters.

6. T the gman in NM 5/5

   Fast, cool cutting with good durability

   I used these on a cordless 4-1/2" grinder for a quick job cutting 3/8" all-thread. They bit through easily with minimal sparks from the guard. The discs lost very little diameter and stayed cool; the thin profile reduces material waste and grinder strain. In a 25-pack they offer strong performance for repeated tasks.

7. B Bob R. 5/5

   Reliable for heavy fabrication work

   I build pergola frames and do a lot of tubing cuts. The 5" size gives more depth than 4.5" discs and they hold up well. They run true, secure tightly to the arbor, and the narrow width focuses on cutting instead of grinding away metal. A 25-pack will last a typical hobby fabricator a long time.

8. T TIF 5/5

   Clean, fast cuts with respectable life

   On 1/8" mild steel tubing the .045" discs slice through quickly with little pressure. Letting the grinder stay at speed keeps the cut clean and avoids glazing. The 5" size reaches farther into stock than 4.5" discs, and the 7/8" arbor fits securely. They remained flat and vibration-free during use, and disc wear has been reasonable over multiple cuts.
