Needleguns

Desco Needleguns — or Needle Scalers — are designed with productivity, ergonomics and durability in mind. Desco needleguns are offered in a variety of sizes and are all capable of being outfitted with dust collector attachments for use on flat surfaces, inside corners and pipe. When utilized with Desco critical filtration vacuums, our tools are suitable for applications involving lead abatement, silica dust mitigation and radioactive decontamination.

 

Model 40 Needleguns

Stop repetitive motion syndrome! Using the latest technology for vibration suppression, this dust free needlegun operates with far less vibration than ordinary needle scalers. The 3-CFM air requirement allows this needlegun to operate on a limited air supply.

 

Applications

Needleguns excel at cleaning in and around obstacles where other tools are not effective.

 

Removing coatings

Removing millscale & non-skid

Cleaning castings

 

Removing rust & corrosion

Cleaning angles and corners

De-slagging welds

 

Needles Conform to Shape

Desco needleguns have the ability to conform to the contour of the surface they are cleaning. In the process, the needles adhere to an objects shape while stepping over obstacles and stepping into voids. As a result, needleguns produce excellent results in places where other tools can not.
