Chicago Pneumatic T023990 6 Inch Palm Orbital Sander

Product Description

The CHICAGO PNEUMATIC T023990 is a 6-inch palm-style random orbital sander designed for pneumatic finishing applications. Powered by compressed air at 90 psi with an 18 CFM air consumption rate, it delivers 10,000 orbits per minute through a 0.375-inch orbit diameter. The 1/4-inch inlet connects to a standard shop air supply via a minimum 0.38-inch hose. The PSA (pressure-sensitive adhesive) backing pad accepts standard 6-inch PSA abrasive discs. This tool is sized and weighted for one-hand operation, making it practical for surface prep, paint finishing, and bodywork where extended use is common. Weighing 4.8 pounds, it provides substantial feel without excessive operator fatigue.

The T023990 is suited for automotive body shops, woodworking operations, metal fabrication, and general surface finishing in both residential and light commercial settings. It handles material removal and final finishing passes on large flat or gently contoured panels. Technicians and finish carpenters reach for this class of tool when a larger pad diameter is needed to cover surface area quickly. The random orbital action reduces swirl marks compared to straight orbital tools, making it appropriate for final-stage finishing work ahead of painting or coating.

Key Features

• 6-inch round PSA backing pad accepts standard pressure-sensitive adhesive abrasive discs
• 10,000 OPM operating speed for efficient material removal and finish work
• 0.375-inch (10 mm) orbit diameter balances cut rate with surface finish quality
• 90 psi operating pressure with 18 CFM air consumption — verify compressor capacity before use
• 1/4-inch air inlet with a minimum 0.38-inch (10 mm) hose size requirement
• Palm-grip design at 4.8 pounds supports extended single-hand operation
• No vacuum port — use in conjunction with a separate dust collection setup as needed

Compatibility

Designed for use with standard 6-inch PSA abrasive discs. Requires a compressed air supply capable of maintaining 90 psi and delivering a minimum of 18 CFM at the tool inlet.

Installation Notes

Installation is performed by pneumatic tool technicians or end users familiar with shop air systems. Before connecting or disconnecting the tool, depressurize the air line and verify the supply valve is closed. Ensure the air hose meets the minimum 0.38-inch inside diameter requirement to avoid pressure drop and reduced tool performance. Do not exceed the rated 90 psi supply pressure, and install an inline regulator and water separator to protect the tool and maintain consistent operating conditions.
