3M 7000148245 Flange Adapter 7/8 Inch Flap Wheels

Product Description

The 3M 7000148245 is a stamped and formed sheet metal flange adapter designed to reduce a 1-inch internal diameter core, flange, or wheel bore to fit arbor shafts smaller than 1 inch in diameter. Specifically sized for a 7/8-inch shaft fit, this adapter allows technicians and tradespeople to mount compatible abrasive flap wheels on equipment with smaller spindle diameters without replacing the wheel itself. The stamped sheet metal construction keeps the adapter lightweight while providing a secure, consistent fit during grinding and finishing operations.

This adapter is intended for use with 5-inch through 8-inch diameter abrasive flap wheels where the wheel's 1-inch bore must be reduced to accommodate a 7/8-inch shaft. It is commonly used in metalworking, fabrication, and surface preparation applications in both shop and field environments. Tradespeople working with angle grinders, bench grinders, or similar rotary tools will find this adapter a practical solution when wheel and spindle sizes do not match directly.
