Review on 🦈 Shark Industries PN-20 Die Grinder Cut-Off Wheels 2-Inch x 1/16” x 1/4”, Shark Type-1 Double-Reinforced Thin Wheels with 54 Grit, Max RPM 30,558 (Pack of 10 Cutting Discs) by Jack Bhowmik

Revainrating 4 out of 5

They cut beautifully: Abrasive and finishing materials

They work great. A previous review said they were forever, I would disagree. I did body work on my car and got through 4 or 5. It's all pretty thin steel and I used a combination of these grinding wheels, a saw and my 4 inch router. I haven't had a single explosion, which is good when it comes to those cut-off fiber discs. At $2 a wheel, I'll probably settle for the equivalent of $1 a wheel at the yard store.

Pros
  • Industrial and scientific materials
Cons
  • Protection
