The Mini Pyramidal Mandrel is a specialized mounting accessory designed for enthusiasts and professionals who require absolute precision when using unmounted polishing and grinding tools. This mandrel features a standard 3.2mm (1/8') shank, ensuring a perfect, wobble-free fit with almost all modern rotary tools, die grinders, and flexible shafts. Its heavy-duty construction is built to withstand high rotational speeds, providing the stability needed for delicate detailing work.
Distinguished by its unique pyramidal tip shape, this mandrel offers an optimized seating surface for your accessories. The 4mm tip diameter is engineered to provide a secure grip on small polishing wheels, felt bobs, and rubberized abrasives. The tapered geometry of the pyramid head ensures that your attachments are centered perfectly, which drastically reduces vibration and prevents 'run-out' during high-speed operation.
This mandrel is particularly effective for tasks that involve internal polishing or working in tight geometries where a standard flat-head mandrel might interfere with the workpiece. The streamlined design allows for better visibility and access, while the high-strength steel composition ensures it won't flex or bend under moderate pressure. It is an indispensable tool for jewelers, dental technicians, and hobbyists who demand a reliable, professional-grade mounting solution for their custom abrasive setups.
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.
