3M 15014 Deburring Wheel Mandrel 1/8 in Shank

Product Description

The 3M 15014 is a deburring wheel mandrel designed to mount abrasive deburring wheels onto rotary tools, die grinders, and similar power equipment. The mandrel features a 1/8 inch shank diameter and a 3/16 inch wheel hole, making it a compact, precise-fit adapter for small-diameter deburring wheels. With a shank length of 1-11/16 inches and compatibility with wheels up to 1 inch in diameter and 1/4 inch in maximum width, this mandrel is built for controlled deburring, edge finishing, and light material removal tasks common in metalworking, HVAC fabrication, and mechanical service environments. It is a straightforward, single-piece accessory that connects compatible abrasive wheels to standard rotary tooling.

This mandrel is suited for use in shop and field settings where technicians need to deburr pipe ends, sheet metal edges, drilled holes, or machined surfaces. It is commonly used in HVAC, plumbing, and general mechanical trades when preparing copper, steel, or aluminum components for assembly. The compact shank size allows it to fit into close-clearance areas where larger tooling is impractical. It accepts wheels with a minimum diameter of 1/2 inch and a minimum width of 1/8 inch, covering a practical range of standard deburring wheel sizes.
