This allows for variable speed and shuts off the air completely **Q: I am looking to mount in a lathe quick change tool holder (any one know what the body OD is the blue part)** A: 0.6250",15.87mm according to the mitututoyos, I would make a dual ring assymbly mounted to a tool post, bore the rings six .625 split one ended, drill and thread it to screw the rings closed further to grip the tool. But as always there's more than one way to go about things, I'm sure your could find a 1/2 inch boring bar holder and drill it ou55oversize and put the screws to it **Q: It is leaking air from under the rearend holder when turned on. It does not spin. Just shoots air out of the back. Hose/hose fitting are not leaking*** A: I just returned one with the exac problem. Ive been working on and off for 50 years with small type air grinders but this jewel turned out to be a paste. I was Really disappointed that it didn’t represent its maker very well. One of these shouldn’t be seized just out of box, oiled and connected with correct air supply. **Q: is this any good for use on resin counter tops?** A: I would say it depends on what you're doing. If you're cutting the counter tops then no but if you're etching a design I'd say sure why not. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5 star all the way. *by E***. on January 30, 2025* This is a great tool and works perfectly and is definitely a quality product. Service with this vendor was awesome. I got my product the next morning after ordering it and was able to use it straight out of the box. Even my co-workers liked this and now are planning on ordering one for themselves. I'm very happy with this product and the vendor and I give them 5 stars all the way and would most definitely buy this again. ### ⭐⭐⭐⭐⭐ Tough. *by B***N on February 22, 2026* Tough little tool. Way cheaper than the tool trucks. ### ⭐⭐⭐⭐ Great value but no replacement parts. *by J***H on July 3, 2022* At the time of purchase this was about $50. This tool is very good for that price point. If you can supply ~90psi @ 5cfm this tool will perform well. As the tool has aged it does very well for precision grinding and light polishing. eg jewelry, electrical contacts, bearing surfaces, slightly rusted metal. using the dremel ezlock cutoff wheels this tool will cut like a small high speed low torque dremel. the down side is at low rpm there is almost no torque for cutting applications, plastic is the worst offender. however when polishing or grinding a precise piece this tool is nice because it will not hog out material like a traditional die grinder or a dremel. Over all i would buy again but i would prefer to see a rebuild kit so i can replace the bearings and vanes like IR and Sioux tool offer. ## Frequently Bought Together - Astro Pneumatic Tool 218 1/8" Pencil Type Die Grinder - 56,000RPM,Black,gold,blue, 42377 - 20 Pcs Carbide Burr Bits 1/8" Shank Compatible with Dremel Milwaukee Metal Grinding Wood Stone Steel Carving Cutting Engraving Grinder Kit Attachment Rotary Tool Accessories Set Harder Than Diamond - Carbide Burrs Set JESTUOUS 1/8 Shank Diameter Double Cut Tungsten Carbide Burs Rotary File Carving Grinding Bit for Die Grinder Rotary Drill Tool 20pcs --- ## 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.hr/products/6194340-astro-pneumatic-tool-218-1-8-pencil-type-die-grinder](https://www.desertcart.hr/products/6194340-astro-pneumatic-tool-218-1-8-pencil-type-die-grinder) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
