Vernon CCH-CCH1890 Adjustable Depth Drill Countersink

Product Description

The VERNON CCH-CCH1890 is an adjustable depth drill countersink designed for precision holemaking in metal, wood, and composite materials. Built from high-speed steel, this right-hand countersink features a 3/8 inch cutter diameter, a 90-degree included angle, and a 45-degree centerline angle. The adjustable depth collar, measuring 1/4 inch in thickness, allows the operator to set consistent countersink depth across repeated operations without re-measuring. With a cutter head length of 3/4 inch, it is suited for use in production environments and field fabrication work where repeatable results are required.

This countersink is used in applications requiring clean, accurately angled seat profiles for flathead fasteners in metal fabrication, woodworking, and light manufacturing. Compatible with standard drill configurations accommodating up to 12 drill bit sizes, it fits into typical drill press, hand drill, and CNC drill setups. Its adjustable collar makes it a practical choice for sheet metal work, cabinetry, and structural assembly where consistent countersink depth is critical across multiple workpieces.

Installation Notes

Installation and use should be performed by a qualified machinist, fabricator, or tradesperson familiar with rotary cutting tools. Always power down and fully secure the workpiece before tool changes or depth collar adjustments. Ensure the collar locking mechanism is tight before beginning any cut to prevent unintended depth variation. Follow applicable shop safety standards and wear appropriate eye protection when operating countersinking tools.
