The Edco 12501RC is a three-pack of right-hand Magna-Blades for Magna-Trap floor grinders, giving concrete surface-prep contractors an aggressive, cost-controlled way to strip soft and thick coatings without gouging the slab. Because each block carries a replaceable, eight-sided tungsten carbide insert, crews get maximum life from every blade by simply rotating to a fresh edge instead of replacing the whole tool.
Built for coating and mastic removal
- Stripping mastic, tacky paint, resins, tar, fiberglass, and heavy industrial build-up from concrete floors.
- Prep work where the coating is at least 1/16 inch thick and can be cut with a knife, the general rule for choosing a blade over a diamond.
- Warehouse, retail, and industrial floor renovations that need fast removal while leaving a CSP 0-1 profile.
Magna-Blades clean by shearing the coating off the surface rather than grinding into the concrete, so the operator removes the failed material without unnecessarily profiling the slab underneath. This right-hand (RH) set is designed for dual-disc grinder models; pair with left-hand blades as your machine requires for balanced, counter-rotating coverage.

Frequently asked questions
What is the difference between the RH and LH Magna-Blades?
RH is the right-hand version used on dual-disc grinders. Dual-disc machines run counter-rotating discs, so they use both right-hand and left-hand blades; match the set to the position your grinder calls for.
What coatings do Magna-Blades remove?
They excel at soft, thick coatings such as mastic, tacky paint, resins, tar, fiberglass, and heavy industrial build-up. A good rule is that if the material is at least 1/16 inch thick and can be cut with a knife, use a Magna-Blade.
Can the carbide be reused?
Yes. Each block uses an eight-sided tungsten carbide insert that can be rotated to a fresh edge multiple times before the block is replaced, which lowers your tooling cost.
Will they grind into the concrete?
No. Magna-Blades are designed to shear coatings off the surface without grinding into the slab, leaving a CSP 0-1 profile.
