Specialised tooling


Countersinking is a technique employed to create a conical hole at the surface of a drilled hole. This is a standard application in steel processing for assembly parts. The conical shape allows the head of a screw or bolt to sit flush with or below the surface of the steel component, providing a smooth finish.

Countersinking uses a specialised tool to cut the tapered shape into the steel.  With the screw or bolt head sitting flush with the surface, countersinking helps distribute the load more evenly, reducing the risk of metal deformation and enhancing the overall strength of the assembly.

Advanced techniques


At Eliott Engineering, we employ high-performance CNC machining for our countersinking services. These machines ensure precise control over the depth and angle of the countersink. Different screws and bolts have different head angles (e.g., 82 degrees, 90 degrees, 100 degrees), so the countersink tool must match the specific angle required for the application.

After countersinking, the hole and surrounding area are cleaned to remove any metal shavings or debris, ensuring a clean and accurate fit for the screw or bolt. Countersinking is essential for achieving smooth finishes, improving load distribution, and ensuring accurate assembly.
