Mini-Arrow Cupwheel (Threaded)
The Mini-Arrow is our most aggressive cupwheel. It’s ideal for intensive grinding on hard concrete or for quick removal of tough coatings, without the extreme tearing effect typical of PCD tools.
Its arrow-shaped segments, angled forward (~10°), are designed to penetrate and slice through coatings and surface imperfections. This geometry enables a dual-action process of scraping and grinding in a single pass — perfect for efficient and fast surface preparation.
The Mini-Arrow is especially effective at removing glue, paint, mastic, thin epoxy, as well as residues from thin-set mortar and grout. It also performs well on sticky or heat-sensitive coatings, with less clogging than traditional cupwheels.
The smaller segment size makes the Mini-Arrow more aggressive than the standard version, but it comes with trade-offs: shorter tool life, reduced stability, increased tendency to jump, and a rougher surface finish. However, its lower segment height improves contact with the slab and adds stability, partially offsetting the reduced control from the smaller segments.
While it can handle thicker and tougher coatings, it doesn’t match the raw power and speed of a PCD tool. If surface finish is not critical and efficiency is the top priority, a PCD is usually the better choice.
Typical applications:
- Removing glue, paint, mastic, and thin epoxy
- Removing sticky or heat-sensitive materials prone to clogging
- Cleaning up thin-set mortar and grout after demolition
- Grinding bare concrete, correcting high spots and trowel marks
- One-step surface preparation: coating removal + concrete profiling
