3M 7010328366 Flange Adapter 3/4 Inch Flap Wheel

Product Description

The 3M 7010328366 is a stamped and formed sheet metal flange adapter designed to reduce a 1-inch internal diameter core, flange, or wheel bore to accept shafts smaller than 1 inch in diameter. This adapter is sized for 3/4-inch shaft fitment and is used with 5-inch through 8-inch diameter flap wheels. Metal fabricators, maintenance technicians, and grinding professionals install this adapter when mounting flap wheels onto angle grinders or bench-mounted arbors with undersized shafts. The sheet metal construction keeps weight minimal while maintaining the dimensional accuracy needed for concentric, vibration-free wheel mounting.

This flange adapter is used in grinding, blending, and finishing applications where flap wheels are the abrasive of choice. It is suited for light industrial and shop environments where operators need to adapt existing flap wheel inventory to fit available tooling. Compatible with 5-inch through 8-inch diameter flap wheels that have a 1-inch bore, core, or flange opening.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel mounting procedures.

Confirm that the adapter, flap wheel, and spindle are rated for the same maximum RPM before operating. Follow applicable ANSI B11 and OSHA abrasive wheel safety standards when mounting grinding accessories.
