If You know the Arrow Cup, You’ll Love the Rapida
If you know the Arrow Cup Wheel, you’ll love the Rapida.
The Arrow has earned its place as a go-to for fast, aggressive grinding — and in our Arrow Cup overview video, you’ll see why it’s built to perform.
The Rapida takes that same trusted DNA and refines it for the toughest, high-strength concrete.
But when the concrete is extra hard, slick, or burnished — the Rapida Cup Wheel takes over.
The Rapida is built for speed and control on the hardest slabs. It takes everything the Arrow does well and pushes it further for jobs that demand faster, cooler, and cleaner grinding under pressure.
What Makes the Rapida Different
The Rapida isn’t your everyday cup wheel — it was curated for the toughest concrete conditions.
Where most soft bonds would overheat or glaze, this high-quality soft bond stays cool and sharp, even on dense, burnished, or high-MPA slabs.
Its cap-cutter segment design gives each pass a crisp, consistent cut that clears material fast without smearing. This wheel thrives on extremely hard concrete, not recommended for soft or abrasive surfaces.
Product Highlights:
High-quality soft bond engineered to stay cool in extreme conditions.
Cap-cutter segments for sharp, efficient grinding.
Purpose-built for hard, burnished, or trowel-smooth concrete.
What Is a Concrete Cap?
When concrete is trowelled and treated with curing agents, it forms a thin, dense top layer known as the concrete cap.
This cap seals in moisture during curing, making the surface extra hard and smooth — almost like a glaze over the slab.
Visually, it can look shinier, darker, or more polished than the rest of the concrete.
It’s tough, strong, and great for durability — but it’s a nightmare for grinders unless you have the right tooling.
The Rapida Cup Wheel’s cap cutter design was built specifically to break through that hardened surface layer, exposing fresh concrete underneath for a faster, cleaner grind.
Why Contractors Love It
Contractors who want results over replacement love the Rapida.
It’s made for those who’ve hit slabs that feel like glass and still need to grind through before lunch.
If you already trust the Arrow Cup Wheel for everyday prep, the Rapida Cup Wheel is your next step up — a serious solution for serious concrete.
