Vacalon HP Mandrels mount rubber polishers, separating discs, diamond discs and wheels on a straight handpiece. A screw passes through the disc and threads into the mandrel body, clamping the attachment firmly for stable work in the lab or the operatory.
The four styles
- Standard – general-purpose, compact; 5 mm head
- Heavy Duty – a thicker upper shaft for more rigidity under load; 5 mm head
- Wide Head Heavy Duty – an 8 mm head that clamps more of the disc or wheel, steadying wider attachments
- Premium – a tapered profile for a more refined feel in the handpiece; 5 mm head
Details

About mandrels
ISO 10323 sets the bore diameters of discs and wheels so that they and the mandrels they run on are interchangeable. A sandpaper mandrel holds the sandpaper used to finish denture acrylic.
A mandrel is an axle, spindle or arbor, usually tapered or cylindrical, placed in the hole of a part to support it while it turns. ISO 13295 covers the mandrels that carry discs and polishers in dentistry.
How mandrels and arbor bands differ
- Mandrels — The holder that goes into the handpiece.
- Arbor Bands — The coated abrasive band itself, not the holder.
- Rotary Accessories — Adapters, chucks and a felt mounted kit, filed beside the mandrels and arbor bands.
What to look at when choosing a mandrel
Fit: the bore of the disc or wheel has to match the mandrel, which is what ISO 10323 standardises.
Size: ISO 2157 sets the nominal diameters of the working part of burs, laboratory burs, grinding instruments, diamond instruments and mandrels, and how they are designated.
ISO 6360 identifies every dental rotary instrument by a 15-digit number.
Speed: OSHA's abrasive-wheel rule has the spindle speed checked against the maximum operating speed marked on the wheel.
