The sandblaster nozzle tip is an important piece of the sandblasting unit. Tips are available in a variety of materials with varying durability, and as such, are subject to wear. The tip chosen for a unit is dependent upon the job at hand.

The blast nozzle accelerates the air and abrasive as the mixture exits the end of the hose. The nozzle tip dispenses the abrasive and controls the flow. Due to this, they are the quickest-wearing component on a sandblasting unit.

CARBIDE TIPS are the most wear resistant. They are expensive but last the longest. They are ideal when using harder abrasives.

CERAMIC TIPS are the second most wear resistant and are the most commonly used. They are less expensive than carbide.

STEEL TIPS wear out quickly, especially with harder abrasives. They are commonly paired with siphon sandblaster units, which use less pressure.

The tip used depends on the job; however, carbide tips are often the most popular.

There are three carbide types available:

COMPOSITE CARBIDE

BORON CARBIDE

TUNGSTEN CARBIDE

Tip size will determine the size of the compressor needed. A larger diameter hole means more air is needed. As tips wear, the hole will get larger and more air will be used. Additionally, more control is needed to work efficiently.

The flow of the abrasive is compacted into a narrow stream at the tip, so the output flow is strong. Tips wear out quickly if the sandblaster has a high abrasive to air ratio. To reduce wear, adjust the valve to lower the ratio. Depending on the grit, another option is using a smaller diameter hose.

Wear and tear should be monitored, because a nozzle tip should not exceed approximately 20% wear. This is measured by noting an increase in the diameter. Changing out nozzle tips when needed will decrease sandblast time and increase efficiency.

When using a sandblaster, it is important to keep safety in mind. Even if sandblasting equipment is regularly inspected, users must stay alert to potential dangers.

Eyes and lungs should be protected from abrasive particles and dust. Ears should be protected from the excessive noise of the equipment.
