We offer both PREMIUM ceramic resin fiber discs (RED in color) as well as PREMIUM aluminum oxide (brown) resin fiber discs in packs of 25! Ceramic is best used for hard metals such as stainless steel and steel. Aluminum oxide discs are best used on soft metals such as aluminum.
Our ceramic shredder flap discs will last 3-4X longer than zirconia discs and will last 8X longer than aluminum oxide! These discs are comparable in quality to the 3M cubitron II discs. The Ceramic grain provides increased durability and faster, more aggressive cutting action than aluminum oxide or zirconia discs.
There are two main right angle grinders that we recommend that are fantastic quality and are only separated by a cord! We recommend one cordless grinder and one corded 4-1/2" right angle grinder.
Cordless Makita XAG04Z goes for around $ 120 and is a GAME changer for people looking for a cordless 4.5" right angle grinder.
Corded Makita 9557PB Grinder goes for about $ 85 and is what we would use for the money!
