Meet the Milwaukee 5 in. D X 7/8 in. X 1/8 in. thick Metal Cutting/Grinding Disc—a purpose-built abrasive for serious metalwork. Designed to fit standard 5" angle grinders with a 7/8" arbor, this disc delivers dependable performance for cutting, shaping, and finishing ferrous metals in one versatile wheel.
The slim 1/8" thickness combines fast material removal with precise control, helping you complete cuts and deburring tasks more efficiently. With a maximum operating speed of 12,250 RPM, this disc is tuned for high-performance metalwork, providing steady, predictable cuts across steel, iron, and other common metals used in fabrication and repair projects.
Key features and benefits
-
Dual-purpose capability: cuts and lightly grinds in a single wheel, reducing tool swaps and downtime on the job.
-
Optimized thin profile (1/8"): minimizes binding and heat buildup while delivering clean, rapid cuts and smooth deburring.
-
Standard compatibility: 5" diameter with a 7/8" arbor fits most common household and professional grinders, making it a practical choice for shop pallets and mobile crews alike.
-
Reliable Milwaukee quality: built for consistent performance in demanding metalworking tasks, from fabrication to renovation projects.
-
Boxed packaging: single-disc packaging protects the wheel from contamination and ensures it arrives ready to install.
Use cases and ideal applications
- Cutting through steel plate, angle iron, pipe, and other ferrous components for fabrication and repair work.
- Deburring and smoothing rough edges after cutting, weld prep, or fabrication, yielding cleaner joints and safer finishes.
- Notching and trimming metal profiles in garage, workshop, or job-site environments where versatility is valued.
- Quick material removal on light to moderate grinding tasks without switching tools mid-project.

Why choose this Milwaukee disc over alternatives
When you’re tackling metalwork, predictable performance matters as much as raw cutting power. This disc from Milwaukee combines a refined thin-profile design with a robust construction that’s built to withstand regular use in fabrication, maintenance, and repair settings. The 7/8" arbor is a staple in many grinders, reducing compatibility concerns, while the 12,250 RPM rating provides ample speed for efficient cuts without sacrificing control. If you’re balancing cutting speed, edge finish, and reliability on ferrous projects, this disc offers a practical, shop-tested solution that keeps you moving.
Practical tips for best results
- Inspect the disc for any cracks or damage before use; never install a damaged wheel.
- Always use the appropriate guard and wear eye protection, hearing protection, and gloves when operating an angle grinder.
- Match the wheel’s RPM rating to your grinder’s maximum speed to avoid wheel failure or unsafe conditions.
- Work with controlled, steady passes to maintain edge quality and extend the disc’s life.
- Keep the workpiece cool with intermittent cuts to reduce heat-related edge discoloration and warping.
