Pro-source PROSG-14045-40 Straight Air Die Grinder 40000 Rpm

Product Description

The PRO-SOURCE PROSG-14045-40 is a straight air die grinder designed for material removal, deburring, porting, and surface grinding in industrial and trade environments. Running at up to 40,000 RPM on 90 psi shop air, it delivers 0.45 horsepower and draws 1.71 CFM. The 1/4 inch (6 mm) collet accepts standard die grinder bits, burrs, and mounted points. A rear exhaust design directs spent air away from the workpiece and operator. Machinists, fabricators, pipefitters, and maintenance mechanics are the primary installers and users of this tool.

This straight die grinder suits precision grinding, deburring weld seams, porting cylinder heads, and cleaning up castings in fabrication shops, maintenance facilities, and production lines. The compact straight-body format allows access to restricted areas where angle grinders cannot reach. It is suited to both light-duty finish work and sustained material removal tasks where consistent air supply at 90 psi is available.

Designed for use with standard 1/4 inch shank die grinder accessories including carbide burrs, mounted grinding stones, and abrasive points. Requires a compressed air supply capable of delivering 90 psi and at least 1.71 CFM.

Installation Notes

Installed and operated by machinists, fabricators, and maintenance mechanics familiar with pneumatic tools. Before connecting to an air line, verify the supply pressure does not exceed the rated 90 psi and that an inline filter-lubricator is present to protect internal components. Always install the collet and accessory securely before applying air pressure, and inspect burrs or mounted points for cracks or damage prior to use. Follow applicable shop safety requirements including eye protection and guarding when operating at high RPM.
