Diamond-tipped core bits for wet coring drill through reinforced concrete, brick, and block. They require coolant or lubricant during drilling and have coolant holes that allow water or cutting oil to flow to the bits' center.

Cobalt steel zero-flute countersinks provide good wear resistance when machining hard materials at high speeds. Zero-flute countersinks have a single flute that passes through the center of the countersink. This minimizes vibration and chatter during use and prevents chips from sticking to the tool. Zero-flute countersinks leave smooth, clean edges on holes and are used to expand the top of an existing hole in a workpiece to ensure screws install flush with the surface of the workpiece. They are commonly used for installing aluminum frame storefronts, glass and window design, and architectural metalworking applications.
