Boring bars are a common tool used to make existing holes bigger and are an essential tool in machining. Steel and carbide constructions are common materials. Steel boring bars may need to be reshaped after moderate use, but carbide bars are stiffer and therefore result in more chatter. You will need different lengths and diameters for different jobs, so consider sets with a range of boring bar dimensions and ratios. Some sets may require slight adjustments to fit your tools and your needs. Ensure that the boring bar set you select is the right fit for the materials you typically work with and will provide a smooth cut without damaging the material.
