Weiler 07725 Brush Arbor 2 Inch Wheel 0.25 Inch Drive

Product Description

The WEILER 07725 is a drive arbor designed to mount small-diameter abrasive wheels and wire brushes onto rotary tools and bench grinders. The arbor accepts a 0.25-inch stem and is compatible with wheels up to 2 inches in diameter. With a maximum rated speed of 20,000 RPM, it is built for high-speed grinding and surface preparation applications. Licensed tradespeople and maintenance professionals use this type of arbor adapter when a direct-mount spindle is not available or when switching between wheel sizes on a common machine platform.

This arbor is suited for light fabrication, weld cleanup, deburring, and surface conditioning tasks in both shop and field environments. It is commonly used in metalworking, HVAC fabrication, plumbing rough-in work, and general mechanical maintenance where small-diameter wire wheels or grinding discs need a secure, concentric mount. The 0.25-inch drive size fits a wide range of compatible rotary tool spindles and drill chucks.

Installation Notes

Installation is performed by trade professionals or experienced end users familiar with rotary abrasive tooling. Always power down and disconnect the tool from its power source before mounting or removing the arbor. Verify that the wheel or brush arbor hole matches the 0.25-inch stem diameter before assembly, and confirm the mounted assembly does not exceed the 20,000 RPM maximum rated speed of the arbor. Follow applicable ANSI B7.1 safety standards for abrasive wheel mounting and guard use.
