Vernon CCH-CCH1870 Adjustable Depth Drill Countersink

Product Description

The VERNON CCH-CCH1870 is an adjustable depth drill countersink designed for controlled countersinking in metal, wood, and composite materials. Built from high speed steel, it delivers consistent cutting performance across repeated use. The tool features a 3/8 inch cutter diameter with a 90 degree included angle and a 45 degree centerline angle, making it suited for standard flat-head fastener seat preparation. Adjustable depth control allows the installer to set consistent countersink depth across multiple holes without repeated measurement. The 1/4 inch collar thickness provides a stable stop reference during operation.

This countersink is used in fabrication, assembly, and maintenance applications where flush or recessed fastener seating is required. Typical install scenarios include sheet metal work, woodworking, and general mechanical assembly. The right-hand cutting orientation is compatible with standard drill press and hand drill setups. The 3/4 inch cutter head length and 3/16 inch drill compatibility make it suitable for pilot-hole-guided countersinking on light to medium gauge workpieces.

Installation Notes

Installation and use of this countersink should be performed by a machinist, fabricator, or qualified tradesperson familiar with rotary cutting tools. Ensure the drill or press is fully powered down and the chuck is secured before adjusting the depth collar. Eye protection and appropriate workholding are required during operation. Follow all applicable shop safety guidelines and tool manufacturer procedures when setting cutting depth and spindle speed.
