Pferd 33700087 Threaded Arbor Die Grinder 1/4 Inch

Product Description

The PFERD 33700087 is a threaded arbor designed for use with die grinders in metalworking, fabrication, and surface preparation applications. Threaded arbors serve as the mounting interface between a die grinder spindle and abrasive accessories such as mounted points, buffing wheels, or sanding drums. This arbor features a 1/4-inch shank diameter, making it compatible with standard 1/4-inch collet die grinders. It is a single-piece accessory sold individually and is well suited for technicians and tradespeople who need a reliable, direct-fit arbor for rotary tool setups.

This threaded arbor is appropriate for light industrial and trade shop use where die grinders are employed for grinding, deburring, polishing, or surface blending. It is typically used in HVAC fabrication shops, pipefitting operations, electrical panel fabrication, and general mechanical service environments where die grinders are part of the standard tool inventory. The 1/4-inch hole size and shank diameter align with widely used collet sizes in pneumatic and electric die grinders.
