Reverse Counterbore: 1/2" Dia, 1/4" Pilot Hole, 4 Flutes, Solid Carbide MPN:191-5L

Reverse Counterbore: 1/2 Dia, 1/4 Pilot Hole, 4 Flutes, Solid Carbide is a high-quality tool designed for professionals working with metal materials requiring precise counterbores on thin materials or delicate components. The 1/4 pilot hole allows for stable drilling while the 4 flutes ensure efficient chip removal without damage to the workpiece surface. Solid carbide construction ensures durability, allowing this tool to perform reliably in various machining applications such as automotive repair shops or aerospace engineering facilities. The reverse counterbore feature makes it perfect for situations where traditional countersinks might create weak points or structural issues when joining materials. By using the Reverse Counterbore instead, engineers can maintain material integrity and provide clean, precise counterbores every time without worrying about tool slippage, damage to the workpiece or inconsistent results due to improper countersinking techniques.
