Schaefer Brush 93516 Tube Brush 5/8 in Stainless Steel

Product Description

The SCHAEFER BRUSH 93516 is a double stem, single spiral tube brush built for cleaning the interior walls of tubes, pipes, and small-bore openings. The stainless steel bristles and stainless steel brush construction make it suitable for use in corrosive environments where carbon steel tooling would degrade. At 5/8 inch in diameter and 6-1/4 inches overall length with a 4-inch brush length, this brush fits tight passages that larger tools cannot reach. The male connection end allows it to attach to a standard extension rod or drill chuck for powered or manual operation. Plumbers, HVAC technicians, and maintenance professionals keep this tool on hand for tube-cleaning and deburring tasks.

This tube brush is used in applications where consistent bore cleaning is required, including heat exchanger tubes, condenser tubes, copper pipe fittings, and similar small-diameter passages. The double stem and single spiral configuration holds the bristles firmly in place during rotation, delivering even contact along the full brush length. It is equally suited to shop bench work and field service. The male connection type makes it compatible with threaded extension handles and standard drill chucks commonly used in mechanical and plumbing trades.

Installation Notes

This brush is installed by threading the male connection end into a compatible extension rod or securing it in a drill chuck before inserting it into the bore. Inspect the bore for sharp edges or obstructions before use to avoid bristle damage or jamming. When using with a power drill, run at low RPM to prevent bristle flare and uneven wear. No special tools or trade licensing are required, but appropriate eye protection should be worn during power operation.
