Burrs created during cross-drilling can affect dimensional tolerances, cause part misalignments, and limit the overall efficiency of machined components. For manufacturers, machinists, and metalworkers, surface finishing success begins by choosing the right deburring tools for removing cut, torn, folded, and jagged metal.   Miniature deburring brushes with abrasive-filled nylon filaments have their advantages, but all-stainless steel tools are especially tough and long lasting. Plus, unlike other types of metal brushes, the filaments of all-stainless steel tools won’t corrode and leave after-rust deposits on finished parts. As a full-line supplier of surface finishing solutions, Brush Research Manufacturing (BRM) has the tools you need for deburring smaller cross-drilled holes. ## **Stainless Steel Deburring Brushes** ![Miniature Brush Kit](https://blog.brushresearch.com/hs-fs/hubfs/Blog_Images/Miniature_Brush_Kit.jpg?width=250&name=Miniature_Brush_Kit.jpg "Miniature Brush Kit")BRM’s family of [Series 81A brushes](https://info.brushresearch.com/miniature-deburring-brushes-series-81a) feature an all-stainless steel construction and can be driven by hand or used under power. These deburring tools have an overall length of 3” and come in a variety of brush diameters. If your only option is to buy a large set of tools, the cost may keep you from investing in the deburring solutions that you really need. That’s why BRM offers a [12-piece mini-brush kit](https://info.brushresearch.com/download-miniature-deburring-brush-12-piece-kit-brochure). Choose Series 81A stainless steel brushes for workpieces made of cast iron or steel. These miniature deburring tools are great for removing chips, breakout burrs, micro burrs, and other surface imperfections that can affect part quality and consistency. BRM’s miniature deburring brushes can also be used for surface preparation, internal cleaning, and rust removal. ## **Deburring Tool Specifications and Use** Series 81A deburring tools feature .003” filaments and are available in a variety of sizes, including very small brushes with diameters of .014”, .018”, and .020”. These deburring tools may be small, but they can have a big effect on your parts finishing operations. For example, by removing small surface imperfections from hard-to-reach areas, miniature deburring brushes can improve part quality and consistency.   [Series 81A](https://info.brushresearch.com/miniature-deburring-brushes-series-81a) deburring tools are also easy-to-use. Because they’re non-loading, they won’t clog with debris. To run a tool under power, just chuck the metal stem in a handheld electric drill. Don’t reverse the brush inside the hole, however. For manual deburring, use Series 81A deburring tools with BRM’s double-end pin vise. Built with double collets on both ends, it’s a safe and reliable tool-holder. ## **Find Mini  Cross-Hole Deburring Brushes at IMTS** Are you headed to IMTS 2016 in September?
