Vernon CCH-CCH1660 Adjustable Depth Drill Countersink

Product Description

The VERNON CCH-CCH1660 is an adjustable depth drill countersink designed for precision holemaking in metalworking and fabrication applications. Built from high speed steel, this countersink features a 5/16 inch cutter diameter with a 90-degree included angle and a 45-degree centerline angle, making it well suited for producing clean, consistent countersunk profiles. The 5/8 inch cutter head length and 1/4 inch collar thickness provide stability and controlled depth adjustment during use. Right-hand cutting geometry ensures compatibility with standard drill press and handheld drill setups. This tool is intended for use by machinists, fabricators, and trade professionals who require repeatable countersink depth without constant manual measurement.

The CCH-CCH1660 fits applications where adjustable countersink depth is critical, such as preparing fastener seats in steel, aluminum, and similar materials. Its drill compatibility number of 19 makes it suitable for pairing with standard drill bit sizes in that range. The adjustable collar design allows the operator to set a consistent stop depth across multiple holes in production or service work, reducing rework and improving throughput in both shop and field settings.

Installation Notes

Installation and use of this countersink should be performed by a qualified machinist or trained trade professional. Secure the workpiece firmly before operation and ensure the drill press or handheld drill is powered off before adjusting or setting the depth collar. Verify that the shank is properly seated and locked in the chuck before beginning any cut. Follow applicable shop safety standards and wear appropriate eye protection during use.
