Highlights
- Structural Components: A Cut off wheel typically comprises an abrasive, a binder, and air holes. The abrasive cuts, the binder shapes and strengthens, and the air holes remove swarf and dissipate heat to prevent damage to the cutting disc from overheating
- Working principle: As the grinding wheel rotates at high speed, the sharp edges of the abrasives on the cutting wheel cut the workpiece. The abrasive particles act like countless knives, constantly squeezing, shearing, and grinding the workpiece material upon contact
- Cutting performance: It adopts a 1/64-inch thin cutting wheel design, with high cutting efficiency and compatible with all 4-1/2-inch angle grinders. It can quickly cut off metal materials such as carbon steel, stainless steel, pipes, iron, copper, etc. (not suitable for aluminum alloys), with high cutting accuracy, and can meet some processing requirements with high dimensional accuracy
- Use field: widely used in machinery industry, automotive industry, construction, hardware and other industries cutting
- Safety precautions: When using abrasive cutting discs, you must strictly follow the safety operating procedures. Operators must wear protective glasses, gloves and other protective equipment to prevent debris generated during the cutting process from splashing and injuring people. At the same time, ensure the stability of the cutting equipment and the firmness of the cutting disc installation to prevent the cutting disc from breaking and flying out when rotating at high speed

Detailed Review
The olyrjie 10-Pack 4 1/2-inch Cut Off Wheels are designed for metalworkers, mechanics, and builders who need efficient slicing through common metals. Built to fit all 4-1/2-inch angle grinders, this pack tackles daily cutting tasks across automotive, machinery, hardware, and construction projects.
Each disc features an ultra-thin 1/64-inch design that delivers high cutting efficiency and tight dimensional accuracy. The wheel structure combines sharp abrasive particles, a strengthening binder, and built-in air holes. As the grinder spins, the abrasive particles act like tiny knives to shear metal, while the air holes continuously remove swarf and vent heat to protect the wheel from overheating.
These discs handle a broad range of materials, including stainless steel, carbon steel, iron, copper, and various metal pipes. However, they are explicitly not suitable for cutting aluminum alloys. Safe operation also demands strict adherence to safety procedures, including wearing protective glasses and gloves to shield against flying debris, along with ensuring the disc is firmly installed and the grinder remains stable to prevent breakage at high rotation speeds.
Verdict: If you need an affordable multi-pack of thin cutting discs for steel, iron, and copper fabrication, this set is a solid choice for standard 4-1/2-inch angle grinders. Just remember to use proper eye protection and avoid using them on aluminum.

FAQ
What metals can these cutting wheels cut?
They are designed to cut carbon steel, stainless steel, iron, copper, and metal pipes. They are not suitable for cutting aluminum alloys.
What size angle grinder do these discs fit?
These cutting wheels are compatible with all standard 4-1/2-inch angle grinders.
How do the air holes in the disc work?
The air holes help clear out swarf and dissipate heat during high-speed rotation, preventing the disc from overheating and sustaining damage.
What safety precautions should be taken when using these wheels?
Operators must wear protective glasses and gloves to protect against flying debris. You must also ensure the equipment is stable and the wheel is firmly installed to prevent disc breakage at high speeds.
