Pferd 33700088 Threaded Arbor Die Grinder 5/8-11

Product Description

The PFERD 33700088 is a threaded arbor designed to adapt die grinders for use with abrasive discs and buffing or sanding accessories. It features a 1/4 inch shank that seats directly into a die grinder collet, and a 5/8-11 threaded spindle that accepts standard grinding or buffing wheels. The center hole size is 3/8 inches, matching a wide range of rotary abrasive accessories. Weighing just 0.08 pounds, this arbor adds minimal mass to the tool setup while providing a secure, threaded connection between the grinder and the mounted accessory. It is sold individually as a single-piece unit.

This arbor is intended for use in metal fabrication, grinding, blending, and surface finishing applications where a die grinder serves as the primary power tool. It is suited for work on ferrous and non-ferrous metals in shop environments. The 1/4 inch shank makes it compatible with standard die grinder collet sizes commonly found in industrial and maintenance-grade air and electric die grinders. Machinists, fabricators, and maintenance technicians typically use this type of arbor when mounting cut-off wheels, flap discs, or buffing pads onto a die grinder platform.

Insert the 1/4 inch shank fully into the collet and tighten securely before attaching any accessory to the threaded spindle. Verify that the accessory being mounted is rated for the RPM output of the die grinder before operating.
