Reverse Counterbore: 3/4" Dia, 1/4" Pilot Hole, 4 Flutes, Solid Carbide MPN:191-9J

The reverse counterbore is commonly used in machining and tooling industries for creating clearance holes and cutting internal threads in a variety of materials, including steel, aluminum, and cast iron. Its compact design makes it an ideal choice for applications where space is limited, while its solid carbide construction ensures durability and precision during operation. This tool is particularly useful for creating accurate fastener pilots on blind holes, or for reducing the diameter of a hole to a precise size.
