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.
Application:
- Jewellery finishing
- Automotive metal trim polishing
- Deburring machined parts
- Model making and restoration
- Precision polishing of small or delicate components
- Insert the mandrel into the rotary tool and tighten the collet or chuck.
Mount the polishing point by:
- Pressing onto post (smooth post mandrel), or
- Screwing onto the threaded mandrel (wheel or cylinder types).
The shank of the rotary cutter is securely locked in place by fitting it in the corresponding collet or making use of a keyless chuck.
Rotation speed:
Most rotary tools have the benefit to adjust the rotation speed. Many tool bits that fit in rotary tools have a maximum speed setting. This can normally be found on the packaging.
All materials react differently to speed and will need the tool bit to rotate slower. It is recommended to start using accessories on the slower speed first, before increasing the speed as needed.
The diameter of the tool bit fitted also determines the rotation speed. The larger the diameter, the slower the speed. If the speed is set too high, it could bend the shank/shaft resulting in injury.
