Frequently Asked Questions
Can I use a regular metal cut off wheel to cut aluminum?
You can, but a standard aluminum oxide disc designed for ferrous metals create intense friction and will load up quickly on aluminum. The heat from cutting melts aluminum particles into the abrasive grains — the disc glazes over and stops cutting, or fails entirely. A disc with an AO+SiC blend is formulated to resist that buildup and stay cutting longer on aluminum and other soft metals.
What metals can this disc cut besides aluminum?
These discs work on aluminum, copper, brass, bronze, and other non-ferrous soft metals. They are not recommended for steel or stainless steel — use a standard ferrous-rated cut off wheel for those materials.
What angle grinders are these compatible with?
These fit any 4.5" angle grinder with a standard 7/8" arbor — DeWalt®, Makita®, Metabo®, Milwaukee®, Bosch®, and most other brands. Max RPM is 13,300, so confirm your grinder's rated RPM does not exceed that before use.
Are these discs certified or safety rated?
Yes. These discs are MPA Tested and comply with ANSI B7.1 and EN 12413. Manufacturing is ISO 9001 certified. Max RPM is marked on each disc — do not exceed it.
