Maximize Wet Suppression

In addition, take these steps to maximize wet suppression:

• Add small amounts of water into bailing air. This is known as "wet drilling."
• Use equipment with a needle valve control for proper regulation of the water flow rate.
• Add water slowly until the visible dust cloud has been significantly reduced.
• Use a water filter in front of the needle valve control, so that it does not get blocked by small debris in the water system.
• Do not use more water than is needed to control the dust. Using just the correct amount of water will increase the bit life.
