Vernon CCH-CCH3750 Adjustable Depth Drill Countersink

Product Description

The VERNON CCH-CCH3750 is an adjustable depth drill countersink designed for precision holemaking in metalworking and fabrication applications. Built from high speed steel, this countersink features a 5/8 inch cutter diameter and accepts a 3/8 inch drill. The 90-degree included angle and 45-degree centerline angle make it well suited for standard countersink profiles. The 5/16 inch collar thickness provides stable depth control, and the adjustable depth stop allows the operator to set consistent countersink depth across repeated operations. Right-hand cutting orientation is standard.

This countersink is used in holemaking operations where a clean, repeatable countersink seat is required before fastener installation. Typical applications include metalworking, light fabrication, and maintenance tasks where screw or bolt head seating must be flush or recessed. The adjustable collar makes it practical for production runs or repetitive single-piece work. The 1-1/4 inch cutter head length provides adequate clearance for most standard workpiece thicknesses encountered in trade and shop environments.

Key Features

• Adjustable depth collar for consistent, repeatable countersink depth

Compatibility

Designed as a standard replacement or new-installation adjustable depth countersink for use with 3/8 inch diameter drills in holemaking applications requiring a 90-degree included angle countersink profile.

Installation Notes

Install this countersink into a compatible drill chuck, ensuring the 3/8 inch shank is fully seated and secured before operation. Set the adjustable collar to the desired countersink depth and lock it in place before beginning repetitive operations. Always power down the drill press or hand drill and allow the spindle to come to a complete stop before adjusting the collar or removing the tool. Use appropriate eye protection and secure the workpiece firmly to prevent movement during cutting.
