Fitted with six HSS blades, this deburring tool is a perfect complement to the essentials in a machinist tool box or construction site. **Ensure that appropriate eye protection is worn during use.**

VERSATILE: Our burr removal tool is suitable for use with a variety of materials, from plastics to metals, and even wood. Whether you need a deburring tool for metal or to smooth out a new cut in plastic or resin, this tool provides a safer surface and an extra level of polish to a fresh cut. This tool’s internal deburring design also allows it to punch holes in metals and other material, and it can even drill counter sinks.
