In surface preparation, choosing the right diamond segment on your cup wheel can make all the difference. With a wide range of designs engineered for specific concrete types, material removal, and applications, each style serves a distinct purpose. The right choice doesn’t just improve your results, it can make the job feel a thousand times easier.
Arrow Cup Wheel
The Arrow segment is designed for aggressive grinding and fast material removal. Its V-shaped profile cuts through coatings like a ship’s bow, tearing and pulling away layers as it moves. This versatile design allows you to prep concrete and remove coatings in a single step, saving both time and effort on site.
Best for:
- Removing thin vinyl glue
- Removing carpet glues
- Stripping light coatings
- Removing mortars
- Aggressive concrete grinding
Ideal for early-stage surface preparation when speed, bite, and aggressive material removal matter most.
Spiral Seg Cup Wheel
Spiral segment cups are ideal for edging work with hand grinders. With fewer segments, these tools deliver greater speed and a more aggressive cut, perfect for fast material removal. Cups with more segments are better suited for softer concrete and abrasive materials such as thin-set, providing smoother control and reduced wear.
Spiral segments are also known for leaving distinctive circular or horseshoe-shaped marks on concrete, a characteristic to keep in mind depending on your desired finish.
Best for:
- Removing soft materials
- Removing abrasive materials (thin-set)
- General concrete preparation
Best for detailed edge work and fast removal where control and precision are key.
Teardrop Cup Wheel
Commonly known as the “Wheel of Death,” the teardrop cup wheel is built for the toughest surface preparation jobs. Its distinctive interspersed hole pattern maximises airflow to keep the tool cool, while the heavy-duty segments rip through concrete, coatings, and adhesives with ease.
Available in 5-inch and 7-inch diameters and a range of grit options, this cup wheel is engineered for high performance and fast removal when the job demands power and precision.
T-Seg Cup Wheel
The T-shaped segment leaves a smooth concrete surface creating a contaminant free environment. The design of these segments prep edges, reducing gouge marks and improving uneven wear.
Best for:
- Removing Light coatings
- High Spots/Uneven floor
- General Concrete preparation for coating
Designed for the toughest removal jobs, delivering raw power, speed, and efficiency when you need maximum performance.
