As a machinist, the amount of metal you remove may not need to be more than .00001", (one ten millionth of an inch). However, that's to be very 'technically literal'. Gauge blocks or pin-gauges, in mold & tool making instances would be very concerned about .00001". Still, my point is that, in metal materials, one must remove a certain amount of that metallic surface in order for it to be polished. The ramp of a 1911 would likely polish up easily providing the gun maker didn't leave tool marks deeper than .0001" (one, one ten thousandth of an inch). The American measurement system in machine shop and manufacturing in general, has always made it hard to explain to someone who would typically note "one tenth of an inch" like this: 0.100. In fact, in a machine shop, if you said something like "face-off one tenth", the machinist would remove only this much material: 0.0001, which is extremely small. An average human hair is about .005". One tenth of a human hair is .0005". Therefore, "one ten thousandth of one inch is .0001", which is 5 times smaller than .0005" and about 1/50th of a human hair... I guess this is why they're trying to convert to the metric system. I retired almost 20 years ago and even then, there was a lot of resistance to converting to the metric system because the measure tools, cutting tools, blueprints, and the general machining references would all have to change. Just the machinist's standard set of measuring tools that each experienced machinist of 5 to 6 years or more, owned, would have cost well over $500 in 1980, and over $1100 in 1987. Very few of the tools purchased before 1985 included a metric scale and many still don't. I owned an advanced set of hand tools purchased over a 25+ year time span. In 1992, I was contracted to a small tool-making machine shop, which was broken into and all the tools were robbed. The company's insurance would only pay 80% of each man's replacement tool costs. I received a $4200 check and I was not very happy about it... So you can see why many American machinist don't want to switch to the metric system. It could potentially be very expensive and that's just one aspect of at least five conversion points, which the complete conversion could cost. FWIW **Q: can you use this as a final polish on agate?** A: Thank you for asking your question. Our polishing compound is 400 grit and not something you would use for a finishing compound. We would recommend you get a jewelers rouge with a higher grit to do the final polish on agate. **Q: It is suitable for polishing glass..?** A: No, Dremel 421 polishing compound will not polish glass. **Q: Can anyone say with authority what the grit size is and what material the grit is? Is it diamond or quartz/sand or something else?** A: Hello, The compound is 400 grit. It is 76% silicon carbide and 24% vitrified bond. It is not classified hazardous. ## Customer Reviews ### ⭐⭐⭐⭐ Review *by A***ー on 9 May 2018* 内容量が少ないのか気になりますか、使い勝手がよく色々な素材に使えます。 ### ⭐⭐⭐⭐⭐ Review *by J***N on 18 April 2024* Compré este compuesto para la amoladora dremel tengo que decir que el pulido que hace es espectacular,sobre todo si son para superficies pequeñas,he quedado satisfecho con el producto ### ⭐⭐⭐⭐⭐ Review *by A***W on 28 October 2024* I bought this product to polish the brass house numbers that were tarnished now they shine again thanks to this polishing compound from dremel ## Frequently Bought Together - Dremel 421 Polishing Compound - 100PCS Polishing Buffing Wheel for Dremel Polishing Kit, Polishing Wheel for Dremel Tool Accessories, with 1/8" Shank for Dremel Buffing Wheels - Dremel 726-01 Cleaning & Polishing Rotary Tool Accessory Kit with Storage Case, 20-Piece Set - Includes Buffing Wheels, Polishing Bits, and Compound --- ## 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.in/products/205146130-dremel-421-polishing-compound](https://www.desertcart.in/products/205146130-dremel-421-polishing-compound) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-23*
