Flexovit® Shank Mandrel Adaptor for Die Grinder Wheels 

The Flexovit® Shank Mandrel Adaptor is a high-quality accessory designed to securely mount Type 1 cut-off wheels and other die grinder wheels onto standard die grinders and rotary tools. Engineered for precision, durability, and safety, this mandrel adaptor ensures optimal performance and compatibility across a wide range of industrial cutting and grinding applications.

Crafted from premium-grade steel, the Flexovit® Shank Mandrel is built to withstand high RPMs and extreme conditions. Its rugged construction ensures maximum clamping strength and resistance to bending or deformation, even under heavy loads. The mandrel features a standard 1/4" or 3/8" shank size (depending on the model), making it compatible with most pneumatic and electric die grinders. It accepts wheel thicknesses from 1/32" up to 1/8", supporting cut-off wheels with small diameters such as 2", 3", and 4".

Ideal for use with Flexovit® Type 1 cut-off wheels, this mandrel adaptor enables fast, precise cuts in metal, sheet steel, tubing, and other materials. It’s frequently used in automotive repair, metal fabrication, construction, and general maintenance work—especially where access is limited, and smaller wheels are required.

Installation is quick and secure, thanks to the easy-to-use screw clamp mechanism that locks the wheel in place. Flexovit® ensures that every mandrel meets strict safety standards, including compliance with ANSI B7.1 for powered abrasives.

Whether you're a professional fabricator or a maintenance technician, the Flexovit® Shank Mandrel Adaptor is the trusted choice for safe, reliable wheel mounting on die grinders.
