Diameter 4-1/2" (115MM), bore 22.23mm, 5mm deep double segments,Steel Core:3mm,Grits:40/50;Max RPM 13300 Efficient:larger grinding diamond double segments for grinding large amounts of material removed quickly,finer finish,controlled grinding very effective, and time saver Durable:strong body treated by heat,5mm deep diamond segments and better quality diamond matrix for longer life Light weight,vibration-free designs greatly reduce operator fatigue and it's holes provide more efficient dust collection Dry or Wet use on Angle Grinders,Floor Grinding,Polishers and Grinders to grinding concrete masonry,rock. Works great on Concrete Masonry rock stone surfaces

Package included: 1pc 4-1/2" (115MM)Angle Grinder Grinding Double Row Cup Wheel Wet/Dry Use Concrete Masonry,Block Concrete Floor Grinders

Feature:

1.Diameter 4-1/2" (115MM), bore 22.23mm, 5mm deep double segments.

2.Double row of diamond segments for fast, controlled grinding and Open segment layout reduces risk of loading/clogging.

3.Durable:strong body treated by heat,5mm deep diamond segments and better quality diamond matrix for longer life.

4.Light weight,vibration-free designs greatly reduce operator fatigue and it's holes provide more efficient dust collection.

5. 4" Smaller diameter diamond grinding wheels are useful for smaller sections of floor or edges.

6.Larger diameters spin faster (and therefore cut faster) and are more stable and less likely to dig into the concrete surface.

Application Machine:

Can be fixed on hand held angle grinder or floor grinding machines

Application:

Engineered for dry or wet concrete smooth grinding, leveling, or coating removal,Finishing,Rough deburring and Shaping of construction material surface,stone, masonry,blocks, kerbs
