Vernon CCH-CCH2790 Adjustable Depth Drill Countersink

Product Description

The VERNON CCH-CCH2790 is an adjustable depth drill countersink designed for precision holemaking in metalworking and fabrication applications. It features a 0.5-inch cutter diameter with a 90-degree included angle and a 45-degree centerline angle, making it suitable for producing clean, consistent countersunk profiles. The cutter head measures 1 inch in length, and the collar thickness is 0.25 inches, allowing for controlled depth adjustment during use. Constructed from high speed steel, this countersink is built to handle the cutting demands typical of production and maintenance environments. Installation and operation are performed by machinists, tool and die professionals, and skilled fabricators.

The CCH-CCH2790 is sized for compatibility with a Letter K drill and is suited for countersinking operations in light to medium-duty shop environments. The adjustable depth collar makes it practical for repetitive operations where consistent countersink depth is required across multiple workpieces. It is appropriate for use in manual drill presses, CNC setups where adjustable countersinks are applied, and bench-top fabrication work.

Installation Notes

This countersink is installed and operated by machinists or fabricators using a drill press, handheld power drill, or compatible CNC equipment. Always secure the workpiece firmly before beginning the countersinking operation and ensure the spindle is fully stopped before adjusting the depth collar. Verify that the cutting tool is properly seated and the collar lock is tightened before initiating a cut. Follow applicable shop safety protocols and wear appropriate personal protective equipment when operating cutting tools.
