The Reinforced Mini Screw Mandrel is a fundamental accessory for any serious rotary tool user, providing a secure and stable mounting point for a wide variety of unmounted wheels and discs. Built for durability, this mandrel features a 3.2mm (1/8') shank, making it universally compatible with Dremel tools, die grinders, and flexible shafts. Unlike standard light-duty mandrels, the reinforced design offers superior rigidity, ensuring that your cutting, sanding, or polishing wheels remain perfectly centered even during high-RPM operations.
At the business end, the mandrel features a 4.4mm tip diameter in a precise cylindrical shape. This robust head provides a wide surface area to clamp down on accessories, significantly reducing the risk of discs slipping or shattering under load. The screw-top design allows for quick and easy accessory changes; simply unscrew the top, place your wheel or disc onto the threaded post, and tighten it back down for a rock-solid fit.
This mandrel is specifically engineered to handle the increased torque and pressure of professional-grade tasks. Whether you are mounting small cut-off wheels, felt polishing bobs, or sanding discs, the reinforced construction minimizes vibration and prevents the shank from bending. It is the ideal choice for craftsmen who require a dependable, long-lasting hardware solution for their precision grinding and detailing projects.
