Can be used with a standard electric drill.
Make a half-round mark, then hold the drill straight.
Reduced drilling speeds, low drilling pressure, and increased use of water lubrication will greatly extend the life of the drill bits.
Use coolant.
Minimum pressure.
For drilling granite, marble, masonry, concrete, tile, ceramic, hard plastic, etc.
As a general rule, the smaller the diameter of the bit, the higher the drilling speed.
The harder the material, the slower the drilling speed should be.
If you smell a burning smell, back off! Either your speed is too high or the pressure you are applying is too much.
Your drill bit should never be hot to the touch, not even lukewarm..
