Review: Perfect for polishing jewelry, metals etc… - This is a wonderful polishing compound for use on silver/ gold/ stainless steel jewelry or other items like that. I would suggest using with soft wool/ fabric dremel polishing wheel tools. The softer the better. Very good product and quality. Review: It is best to wipe down the surface with a wet cloth ... - I currently work as a janitor and decided to try out this product in addition to the products provided by my company to clean stainless steel and metal dispensers and handicap bars, as well as the plastic toilet paper dispensers. This product is very affordable. I purchased this product for under 10 dollars, with most of the options having a free-shipping option available. The product arrived in 2 days which was extremely quick. I did expect the container of product to be larger but realized that a little goes a long way. This product can be applied with a brush or a soft cloth. The brush and other accessories would have to be purchased separately if one wanted to go that route. It is best to wipe down the surface with a wet cloth first to remove any excess dirt and then dry it with a dry cloth. I placed a small amount of the compound on the cloth and applied it to the areas that needed polishing. I expected it to be somewhat clumpy as it is a fairly thick product. However, it was quite the opposite. When applied, the product spread on nice and even. The smell of the product is tolerable and not too strong and the stain it leaves on the cloth comes mostly out with soap and water. The only complaint I have is the amount of product. I wish there was a bit more product for the price, but again, the product can and does go a long way if used properly. So in all, for the price, it is a cheap and easy quick fix for polishing up metal and plastic products. It gives a shiny and clean polished look. Gets ride of marks, and smudges and even gets rid of some rust, which I didn’t expect! ## Features - Ideal for polishing or brightening - Can be used on metals and plastics - Can also be used to remove light surface imperfections - Apply with cloth or felt polishing accessories and nylon bristle brushes ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00004UDH4 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #46,398 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #24 in Abrasive Finishing Compounds #4,038 in Power Tool Parts & Accessories | | Brand | Dremel | | Color | Silver | | Customer Reviews | 4.4 4.4 out of 5 stars (2,756) | | Date First Available | July 28, 2017 | | Finish | Brushed | | Global Trade Identification Number | 00080596004217 | | Grit Material | Nylon | | Grit Number | 421 | | Grit Type | Light | | Included Components | household-polish | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 0.96 ounces | | Item dimensions L x W x H | 4.13 x 0.17 x 4.13 inches | | Item model number | 421 | | Manufacturer | Dremel | | Material | Solid Compound | | Number of Items | 1 | | Part Number | 421 | | Pattern | Solid | | Power Source | Hand_powered | | Product Dimensions | 4.13 x 0.17 x 4.13 inches | | Shape | Rectangular | | Size | Pack of 1 | | Style | Classic | | UPC | 080596004217 | ## Product Details - **Brand:** Dremel - **Grit Material:** Nylon - **Grit Type:** Light - **Item dimensions L x W x H:** 4.13 x 0.17 x 4.13 inches - **Material:** Solid Compound ## Images ![421 Polishing Compound - Image 1](https://m.media-amazon.com/images/I/51SQtHUSxzL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Can I use this for a feeding ramp on a 1911 45 acp?** A: Technically, you cannot polish a metal surface w/o removing metal. 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 ### ⭐⭐⭐⭐⭐ Perfect for polishing jewelry, metals etc… *by C***N on February 9, 2026* This is a wonderful polishing compound for use on silver/ gold/ stainless steel jewelry or other items like that.
