About This Product
Diamond Disc for Thick Coating Removal
The Alpha® Spike Disc is a diamond-clustered coating removal disc for removing thick epoxy, urethane, glue, and adhesive coatings. Multiple layers of high-quality diamond grits are vacuum-brazed into clustered diamond beads for fast material removal while maintaining cutting performance throughout the life of the disc.
Coating Removal Without Grinding the Concrete Surface
The Spike Disc removes coatings from concrete without damaging the underlying surface like more aggressive PCD cup wheels can, reducing the need for a separate grinding step after coating removal. This makes it suited for restoration and surface preparation where the existing concrete needs to remain intact.
Open-Mesh Design for Reduced Clogging and Heat
A unique open-mesh diamond layout allows removed material to clear the working surface, reducing clogging and the heat buildup that can burn metal surfaces. The sandwiched rubber-cushioned lightweight body also reduces noise and vibration during operation.
Coating Removal on Concrete, Steel, Wood and Composites
In addition to concrete floor coating removal, the Spike Disc can be used on steel, wood, Glass Fiber Reinforced Polymer (GFRP), and Carbon Fiber Reinforced Polymer (CFRP). It is available in 4-1/2", 5", and 7" diameters with 35 or 50 grit and a 5/8"-11 threaded hub. The disc can also be combined with the Alpha Ecoguard G for a virtually dust-free solution.

Common Questions
Frequently Asked Questions
What coatings can the Alpha Spike Disc remove?
The Spike Disc is designed for removing thick epoxy, urethane, glue, and adhesive coatings.
Will the Spike Disc damage the concrete underneath the coating?
The Spike Disc is designed to remove coatings without damaging the underlying concrete surface, reducing the need for a separate grinding process after coating removal.
What surfaces can the Alpha Spike Disc be used on?
It can be used on concrete, steel, wood, Glass Fiber Reinforced Polymer (GFRP), and Carbon Fiber Reinforced Polymer (CFRP).
How does the Spike Disc reduce clogging?
Its open-mesh diamond layout allows removed coating material to clear the working area, reducing clogging and associated heat buildup.
What is the difference between the 35 and 50 grit Spike Discs?
The Spike Disc is available in both 35 and 50 grit configurations. Select the grit appropriate for the coating removal and surface preparation requirements of the application.
What sizes are available?
The Spike Disc is available in 4-1/2", 5", and 7" diameters. The listed models use a 5/8"-11 threaded hub.
Can the Alpha Spike Disc be used with dust collection?
Yes. Alpha recommends combining the Spike Disc with the Ecoguard G for a virtually dust-free coating removal solution.
