Get Inside Hard-To-Reach Areas

The Standard Abrasives™ Unitized Mandrel is a tool attachment designed to hold a small Standard Abrasives™ Unitized Wheel. The 1/4? shank diameter fits a 1/4? power tool collet or drill chuck. An integral part of the overall application, the mandrel helps operators effectively deburr and finish intricate or hard-to-reach areas.

Easy Attachment

Some Standard Abrasives™ Unitized Wheels come with Quick Change Attachment Styles: TS, TR and TP. This mandrel was especially designed for center hole (CH) unitized wheels without Quick Change attachments. The mandrel facilitates easy fastening of the abrasive wheel to the tool. It drives CH wheels with 2-3? diameters and a 3/8? center hole. Made with steel, it is exceptionally durable and long-lasting, so it can stand up to repeated wear and be used during heavy-duty applications.

Max. RPM for this mandrel is 25,100, enabling operators to use it effectively with high-speed wheels and tools.

The Standard Abrasives™ Mandrel is a helpful accessory for tackling hard-to-reach areas and getting inside tight spots on the workpiece.
