Counter Bores (2 Products)

Counter bores are specialized cutting tools used to create flat-bottomed cylindrical holes, allowing fasteners like socket head cap screws to sit flush with or below the surface of a workpiece. These tools are essential for achieving a clean, professional finish in machined assemblies.

How to Choose

Select a counter bore based on the diameter of the fastener head and the pilot size required for your existing hole. HSS taper shank designs are built for heavy-duty use in industrial drill presses, providing the rigidity needed for precise, repeatable results. Ensure the pilot matches your hole diameter for accurate alignment.
