Vernon CCH-CCH2090 Adjustable Depth Drill Countersink

Product Description

The VERNON CCH-CCH2090 is an adjustable depth drill countersink designed for precision holemaking in metalworking and fabrication applications. Built from high speed steel, this right-hand cutting tool features a 3/8 inch cutter diameter, a 90-degree included angle, and a 45-degree centerline angle. The 1/4 inch collar thickness allows repeatable depth adjustment, making it well suited for production work where consistent countersink depth is critical. The cutter head length measures 3/4 inch. Machinists, tool and die makers, and fabricators use this style of countersink for deburring, chamfering, and preparing holes to accept flat-head fasteners.

This countersink is intended for use in drill press, mill, or hand-drill applications across general metalworking, sheet metal, and light fabrication environments. It accepts up to 4 drill sizes, offering versatility across a range of pilot hole diameters. The adjustable depth collar is particularly useful in repetitive production runs where maintaining a uniform countersink profile is required. It is appropriate for both shop and field use by machinists and skilled tradespeople working with ferrous and non-ferrous metals.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-use countersink for standard drill press, milling machine, and hand-drill chucks accepting straight-shank tooling in holemaking and chamfering applications.

Installation Notes

This tool should be installed and operated by a qualified machinist or skilled tradesperson familiar with rotating cutting tools. Secure the countersink firmly in the chuck and verify runout before beginning a cut. Always power down and de-energize the machine before changing or adjusting the depth collar. Use appropriate cutting fluid for ferrous metals to extend tool life and maintain cut quality.
