Question 2

Which surfaces can I safely grind with this cup wheel?

Accepted Answer

You can grind concrete, stone, masonry, tile, and other hard surfaces. The double-row diamond configuration provides faster material removal and a smoother finish on these materials.

Question 3

What benefits does the double-row design provide over a single-row wheel?

Accepted Answer

The double-row design distributes grinding work across two rows of segments, resulting in faster material removal, more even wear, better heat dissipation, and a longer overall wheel life compared to a single-row wheel.

Question 4

What are the key specifications I should know before using it?

Accepted Answer

Key specs include a 7-inch diameter, double-row diamond segments, and compatibility with standard angle grinders. It’s designed for durability and heat resistance to minimize overheating during use.

Question 5

How do I install and use this wheel with an angle grinder?

Accepted Answer

Power off and unplug the grinder, verify arbor compatibility for 7-inch cup wheels, attach the wheel with the proper flange, secure the guard, and tighten firmly. When grinding, use steady, moderate pressure and keep the tool moving to avoid overheating. Always follow your grinder’s manufacturer instructions.

Question 6

What safety precautions should I follow when using this disc?

Accepted Answer

Wear eye protection, a face shield, gloves, and a dust mask if needed. Ensure the grinder’s guard is in place, inspect the wheel for cracks before use, avoid exceeding the wheel’s rated speed, and keep hands and clothing clear of the spinning disc.

Question 7

What kinds of results can I expect in terms of finish and efficiency?

Accepted Answer

You can expect rapid material removal with a smoother finish on hard surfaces. The diamond segments are designed for durability, so you’ll typically achieve longer wheel life and fewer disc changes compared to standard abrasive discs.
