CNC Router Accessories price Description聽 This CNC Router Nut, also known as the ER chuck, is one of the most important parts of a CNC engraving machine and is used for drilling, tapping, iron beds, or as a drill tapping tool on a machining center spindle. It determines which materials you can work with and how accurately you can cut them, and can also be used to reinforce or modify machined parts, in a variety of shapes and sizes. It can be broadly divided into two categories, namely drills and milling drills. Drill bits drive directly into the material to drill, while milling bits cut laterally to remove material from the surface of the workpiece, rather than directly through it.
