How many strokes per minute minimum and maximum?** A: This is ultrasonic and not profiler **Q: Is there any warranty?** A: I'm not sure if there is a warranty but considering the price is not even one quarter of the price on most ultrasonics l considerate a good investment are you smiling regularly with no issues **Q: What kind of air coupler is used in this item?** A: That is an excellent question. The air coupler is not recognizable to me and doesn't fit any connections that I know of (industrial, automotive or ARO), and there is no way to switch it out, so probably going to have to return the item. ## Frequently Bought Together - SI FANG Turbine Reciprocating Pneumatic Ultrasound Grinder Micro Pneumatic Air Pencil Die Grinder Kit for Mould Metal Lapping Filing Grinding Buffing Polishing Sanding Tools - NEIKO 10649A Micro Air Die Grinder | 1/8" (3mm) Capacity | Pencil Type | 54,000 RPM | For Cleaning Dies, Rotors, Backing Plates, Brake Pads, Mounts, Etc. - Astro Pneumatic Tool 218 1/8" Pencil Type Die Grinder - 56,000RPM,Black,gold,blue, 42377 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/141362816-turbine-reciprocating-pneumatic-ultrasound-grinder](https://www.desertcart.us/products/141362816-turbine-reciprocating-pneumatic-ultrasound-grinder) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-31*
