Vernon CCH-CCH2812 Adjustable Depth Drill Countersink

Product Description

The VERNON CCH-CCH2812 is an adjustable depth drill countersink designed for precision holemaking in metalworking and fabrication applications. Built from high speed steel, it features a 1/2 inch cutter diameter, a 90-degree included angle, and a 45-degree centerline angle. The adjustable collar allows the technician to set countersink depth consistently across repeated operations, reducing the need for manual measurement on each hole. The 1/4 inch collar thickness provides stable depth control, while the right-hand cut orientation suits standard drill press and hand drill setups. This tool is suited for professionals who need repeatable, accurate countersinks in production or field environments.

The CCH-CCH2812 is used in metal fabrication, HVAC ductwork assembly, electrical panel work, and general trade applications where fastener heads must sit flush or below a surface. The 9/32 inch drill compatibility makes it a direct fit for standard pilot drill setups. The 1 inch cutter head length provides adequate reach for most sheet metal and structural applications. It is appropriate for use in both shop environments and on-site installations where consistent countersink geometry is required.

Installation Notes

Installation and use of this countersink should be performed by qualified machinists, fabricators, or trade professionals familiar with rotary cutting tools. Secure the workpiece firmly before operation and confirm the pilot drill is properly seated before engaging the countersink. Inspect the cutting edges for wear before each use and replace if chipping or dulling is present. Always follow applicable shop safety standards and wear appropriate eye protection when operating rotary cutting tools.
