Reverse Counterbore: 9/16" Dia, 3/16" Pilot Hole, 4 Flutes, High Speed Steel MPN:190-6K

Reverse Counterbore: 9/16 Dia, 3/16 Pilot Hole, 4 Flutes, High Speed Steel is a precision cutting tool designed for creating blind holes with countersinks in non-ferrous metals such as aluminum, brass, bronze and copper. The high speed steel construction provides optimal durability and sharpness which ensures superior performance over long periods of time - reducing downtime during applications requiring multiple uses. Its reverse tapered cutting head prevents wobbling or walking while drilling thereby enhancing precision & accuracy while saving time on subsequent operations like deburring, dimpling etc. Additionally, the 3/16 diameter pilot hole ensures proper alignment with predrilled holes thereby increasing assembly line efficiency by eliminating human error associated with manual measurements before machining activities begin. In summary, this versatile tool is ideal for various applications across aerospace, electronics, automotive & plumbing industries as it offers ease of use while delivering superior performance when performing operations such as spot facing or blind hole drilling.
