Description
The 4.5 inch Taz disk is a flat, silicon carbide abrasive designed for safe, damage-free removal of coatings like mastic, urethane, thinset, and more — on concrete or wood surfaces. It’s a cost-effective alternative to the Zec disk, offering similar performance with a 7/8” arbor hole.
These abrasive disks use silicon carbide chunks for consistent cutting without scratching or gouging surfaces. They’re flat and non-dished, making them ideal for use with dust shrouds like the Dust Avenger 005 Kit, especially when paired with a Short AVM adapter nut for proper spacing.
The Taz Disk lasts 1–2 hours under typical use, covering several hundred square feet depending on pressure and surface condition. It works well on both residential and commercial job sites. Whether you’re stripping a garage floor or prepping edges and corners, this abrasive performs reliably without damaging concrete. Its affordable price and easy compatibility make it a go-to for smaller grinders and edge work.
Choosing the Right 4.5 inch Taz Disk Grit
Grit options:
-
16 grit – Most popular. Best all around for coatings under 1/8” thick.
-
8 grit – For thick or stubborn coatings above 1/8”.
-
24 or 36 grit – Use when 16 grit feels too aggressive or you need finer finish control.
For floors over 1/8″ thick coating, you may need to grind lightly with a diamond cupwheel afterward to prep for a new coating. This ensures proper adhesion if you’re recoating the surface.
The Taz Disk is widely trusted for mastic removal, fiberglass prep, urethane stripping, and heavy-duty coating removal. Affordable, reliable, and simple to use, it’s a great tool for any surface preparation arsenal. Choose the 4.5 inch Taz disk as a Zec alternative for precision edge work, smaller tools, and lower-cost coating removal.
The 4.5 inch Taz disk offers a reliable balance of performance, control, and affordability for contractors working on small grinders or in tight spaces.
