Threaded parts with diameters less than 0.125 in. are hard to deburr. That’s because the rough edges or ridges left by machining are so small. Heavy nylon deburring tools or butterfly brushes are fine for larger threaded components, but what about the microburrs on smaller threaded parts? They need precise polishing rather than aggressive deburring.

Manufacturers and machinists can send these parts out for deburring, but that increases costs and extends project timelines. Mass finishing techniques have drawbacks, too. Fortunately, Brush Research Manufacturing (BRM) has the solution. That’s the subject of a recent article in Commercial Micro Manufacturing magazine.

As this article explains, BRM makes miniature deburring brushes that enable in-house burr removal. These cost-effective brushing tools support both manual and automated deburring, too. You can use them with your existing CNC equipment, or in pin vise with or without an electric drill.

BRM’s miniature deburring tools comes in different sizes and filament types, so which type do you need? To learn more about the best way to deburr small threaded parts, download Removing Microburrs from Small Diameter Internal and External Threads, an article from Commercial Micro Manufacturing magazine.
