Review on SPTA Carbide Burr Set: 10Pcs 1/4'' Cutting πŸ”ͺ Diameter, Double Cut Tungsten Carbide Burrs for Carving, Polishing, Engraving by David Guliford

Revainrating 1 out of 5

They are made cheaply. They cut well but bend very easily.

I had to open a slot on the aluminum junction box. The shank of the bit bent almost immediately after beginning to use it. I don't think it took a full 2 seconds before it caught the aluminum and bent the racquet shaft. I would be afraid to use them on anything harder than wood for fear it might break and test the effect of your glasses. I wouldn't recommend them to anyone.

Pros
  • Hands-free operation
Cons
  • Some shortcomings
