Vernon CCH-CCH3280 Adjustable Depth Drill Countersink

Product Description

The VERNON CCH-CCH3280 is an adjustable depth drill countersink designed for precision holemaking in metal, wood, and composite materials. Built from high speed steel, it delivers consistent cutting performance across repeated use. The tool features a 5/8 inch cutter diameter, a 90-degree included angle, and a 45-degree centerline angle, making it well suited for standard countersink profiles used in fastener seating applications. The 5/16 inch collar thickness provides stable depth control, and the adjustable depth design allows the operator to dial in consistent countersink depth without repeated measurement.

This countersink is intended for use in holemaking operations where repeatable fastener seat depth is required. It accepts drill bits up to 21/64 inch in diameter and is configured for right-hand cutting. The 1-1/4 inch cutter head length provides adequate reach for most standard workpiece thicknesses. It is appropriate for use in fabrication shops, maintenance environments, and field service applications where controlled countersinking is needed on ferrous and non-ferrous materials.

Installation Notes

This tool is typically installed and operated by machinists, fabricators, or maintenance technicians using a drill press or hand drill. Ensure the workpiece is securely clamped before operation. Set the adjustable collar to the desired depth and lock it in place before beginning the cut. Always wear appropriate eye protection and follow applicable shop safety procedures when operating rotary cutting tools.
