Review on 5-Piece Brazed Diamond Polishing Bit Set With 1/4" Shank For Cutting, Engraving And Buffing Stone, Concrete, Ceramic, And Marble - KangTeer by Pop Henneghan

Revainrating 5 out of 5

Worked as needed on quartz countertop

These are a lot smaller than I expected, but they did the job. I needed to expand a circular airgap hole in my quartz countertop. It took a bit of elbow grease and about an hour of grinding, but managed to use the largest bit here to take the hole from 1.25" to 1.5".

Pros
  • The brazed diamond heads on these bits are strong and long-lasting, making them an ideal choice for repeated use in heavy-duty applications.
Cons
  • High price point
