Delivering Focus and Repeatability
An integral part of any MicroBlasting system, the nozzle provides focus and acceleration to the abrasive stream generated by the blaster. A good nozzle is designed to resist wear. Comco nozzles are manufactured from high-grade tungsten carbide and feature threads that sit away from the abrasive stream. The superior quality of Comco nozzles guarantees the highest level of repeatability with every blast.

What Drives Nozzle Selection?
Select the right nozzle for your application using the following variables:
This incorporates the base material, size and intricacy of the part. For instance, a part with deep bores usually requires an extended nozzle.
Determine if the application requires deburring, texturing, stripping, cleaning, etching or milling. Nozzle distance is important, too. Some nozzles should be held close to a part to carve precise features, some should be held further back to give abrasive room to travel. If you want to cover a wide area, use a large nozzle. If you need to create precise features, use a small nozzle.
Tank Orifice Size
The tank orifice should be 5x as large as the abrasive. The nozzle should be the same size or larger than the tank orifice.
A Note About Rectangluar Nozzles
Rectangular nozzles are not designed to sweep or fan abrasive over a part surface. More often than not, rectangular nozzles are not an efficient option as their design actually slows abrasive down. Rectangular nozzles are designed to make exact rectangular cuts. These nozzles should be held close to a part surface to get precise features. The spot size from a rectangular nozzle grows rounder and uneven as it is pulled away from a surface.
Hi/Performance Nozzles Deliver Faster Results
All of Comco’s nozzles are specifically designed to meet the challenges of micro-precision sandblasting, but our signature line of Hi/Performance nozzles are designed to deliver better results. A properly-accelerated abrasive stream is invisible due to velocity, yet most MicroBlasting applications require a precise and consistent flow. Therefore, the quality of a nozzle cannot be judged on its outward appearance. It must be gauged on results. Our engineers designed Hi/Performance nozzles to deliver:
3-5x More Life
Hi/Performance nozzles are designed to last 3-5x longer than Standard nozzles. In MicroBlasting, the nozzle is the center of the acceleration process, but turbulence inside a nozzle reduces its lifespan. These nozzles pass abrasive carefully and provide a smooth transition at entry and exit points.
30% More Focus
Proper focus ensures every particle strikes the targeted area. Abrasive particles must travel fast and straight to be effective. Hi/Performance nozzles are designed to reduce overspray by 30%.
30% More Velocity
Abrasive moving at high velocities removes material faster. The internal geometry of a Hi/Performance nozzle speeds up particle velocities by 30%.
Hi/Performance nozzles are available for the AccuFlo® and the MicroBlaster® in the straight, round design used in most applications. AccuFlo nozzles fit the ComfortGrip® Handpiece, and MicroBlaster nozzles fit the MicroBlaster Handpiece. All Comco nozzles are color-coded for easy identification.

Easy Fixturing with AccuFlo Nozzles
Thinking about automation? Starting with Hi/Performance AccuFlo nozzles in your manual application will save time when you are ready to automate. The MB2520 Series nozzles are designed to smooth the transition as your production grows.
All AccuFlo nozzles are quicknut compatible, which means installation is quick! The gold quicknut need only be finger tight to lock the abrasive hose onto the back of the nozzle. There is no need for an additional nosepiece, handpiece, or o-ring.
Maintains Nozzle-to-Target Distance
The AccuFlo nozzle is designed to be held just above its carbide tip, which keeps nozzle-to-target distance consistent through hose and nozzle replacements.
The threads on an AccuFlo nozzle are designed to sit away from the abrasive path. Guarding this significant wear point from the abrasive stream dramatically extends the life of the nozzle.
Standard Nozzles Deliver Variety
Most applications benefit from the efficiency and precision of the Hi/Performance nozzle; however if only occasional blasting is required or if the application requires a different approach, reach for a Standard nozzle. Standard nozzles come in a variety of sizes, angles and lengths.
- Round nozzles, ideal for occasional blasting, feature openings ranging from 0.015″ to 0.046″.
- Rectangular nozzles make precise rectangular cuts.
- Angled and extended nozzles direct the abrasive stream into hard-to-reach areas of a part like deep bores.
- Conductive nozzles are designed for static-sensitive applications. These nozzles limit the potential for a static charge to build up and harm a circuit board.
All Comco nozzles are color-coded for easy identification.
Comfort at Your Fingertips
Long hours blasting need not be hard on your hands! Hi/Performance AccuFlo® nozzles come with the bonus of a well-designed holder. Our ComfortGrip® Handpiece eliminates the need for a nosepiece and locks directly to the nozzle. Plus, it is more comfortable to hold and maneuver for long periods of time.
What makes the ComfortGrip® Handpiece such an asset?
- Patented design provides the ultimate in comfort and performance.
- New ergonomic shape and cushioned grip for a natural feel that’s easier for operators to hold.
- Less resistance to motion for enhanced control and reduced fatigue.
- Fewer parts of this design come into contact with abrasive, which means fewer parts to replace.
- Compatible with most popular nozzle sizes: .018″, .030″, .046″, .060″ ID.
