4-1/2" Abrasive Cut-Off Wheels for Metal — Fast, Clean Cuts on Steel, Iron & Rebar
Whether you're trimming rebar on a concrete pour, cutting angle iron for a fabrication project, or slicing through structural steel on a renovation job, running out of cutting discs mid-task kills momentum. These 4-1/2" x 7/8" abrasive cut-off wheels are built for tradespeople and serious DIYers who need reliable performance across a full day's work — not just a single cut.
Each disc measures 4-1/2" (115mm) in diameter with a 7/8" (22.2mm) arbor hole and a slim 0.045" (1.1mm) cutting profile. The 5-pack format means you have backup discs on hand for extended jobs. Constructed from aluminum oxide abrasive bonded under high pressure, these wheels deliver consistent bite and controlled heat dissipation cut after cut.
Ideal for structural steel fabrication, rebar prep before concrete pours, HVAC ductwork trimming, and general metalworking in the shop or on-site. Compatible with most 4.5-inch angle grinders — a go-to consumable for contractors, welders, and home workshop builders.

What is the maximum RPM rating?
These wheels are generally rated for up to 13,300 RPM. Always verify your grinder's RPM does not exceed the disc's rated speed before use.
Are these discs safe to use?
Yes, when used with proper PPE (face shield, gloves, hearing protection) and within the rated RPM. Always inspect discs for cracks or chips before mounting.
What thickness are these cut-off wheels?
These are thin cut-off wheels, typically 0.045" (1.1mm) thick, designed for fast, clean cuts with minimal material loss.
Can I use these for grinding as well as cutting?
No. Cut-off wheels are designed exclusively for straight cutting. Using them for side grinding can cause disc failure. Use a dedicated grinding disc for surface work.
