Counterbores

Counterbores are one of the many types of special high speed and carbide cutting tools we make. They are used to cut distinctive forms on the internal diameter of parts or to make unique design holes in parts. The major advantage of counterbores is that several diameters, angles, and radii can be cut at the same time. You can get them in high speed steel or carbide. At QJ Tool, we use our more than 25 years experience and all counterbores go through our finishing and grinding department where they are ground to the exact form by our highly experienced employees. This process insures only the highest quality counterbore cutting tools.
