Drilling Pressure

 

Increasing the  pressure on diamond bits makes the bit cut faster. Not a good ideal with diamond bits. With a diamond drill bit, it’s very important that you:

 

Use very light downward pressure with a touch n” go technique. Let the “drill cut at its own speed.

 

Use plenty of water as a lubricant. A squirt bottle will often work.

 

Increasing the drill pressure will only increase the friction and heat. This not only burns up your diamond drill bit, but could also fracture or crack the material you are working with.

 

When drilling a hole completely through any material,it is important to :Lighten up the pressure even more when you sense the drill bit is about to break through the backside. This reduces chip out on the backside.
