2.35mm shank diameter is the standard for dental handpieces so compatiblity shouldn’t be an issue, and we’re ordering the 12-piece box because of that it covers most composite finishing steps without needing separate kits.

It runs at 15,000rpm, which is pretty much the sweet spot for silicone and felt heads—too fast and you risk heat buildup, too slow and it won’t cut efficiently, so this spec actually matters for getting a consistent finish.

Basically, the kit mixes silicone, goat hair, leather, silicon carbide, felt, and cotton heads—so for the oral rehab guys doing composite restorations, they’ll have everything from initial contouring to final gloss in one box, though it’s not ideal for heavy metal or ceramic work.

We usually have stock form the Henan facility, but I’d confirm lead time if you need it in under 20 days or so—sometimes the 12-piece packaing gets held up if they’re running a batch of teh larger kits first.

One thing you don’t see on the spec sheet: the silicon carbide heads are denser than the felt ones, so they wear slower—better than standard silicone-only kits for high-volume clinics where heads get swapped every few restorations.

Anyway, the MOQ is one box, and the COA covers purity on abrasive compounds, which is about what you’d expect for a mid-tier composite kit—good enough for most practices but not certified for implant surfaces.
Yes, the 12pcs in the box include different grits and materials—like silicone for pre-polish and felt for high shine—so you can handle a full restoration without grabbing extra tools.
Sure, we can send you the MSDS and a material test report for the silicone and silicon carbide parts. Just ask your sales rep when you place the order.
MOQ is just 1 box, but for five chairs you'll probably want at least 5-10 boxes. We offer volume discounts once you go over 50 boxes.
2.35mm is the standard lab-type shank for slow-speed handpieces, not high-speed friction-grip chucks. It works perfectly with any contra-angle or straight nose cone running at 15,000 rpm.
For 100 boxes, production takes about 7-10 working days, then shipping via sea freight to a US port adds roughly 25-30 days. Air express is faster but costs more.
