Vernon CCH-CCH1850 Adjustable Depth Drill Countersink

Product Description

The VERNON CCH-CCH1850 is an adjustable depth drill countersink designed for precision holemaking in a range of materials. Built from high speed steel, it delivers consistent cutting performance and durability under repeated use. The cutter head measures 3/8 inches in diameter with a 3/4 inch cutter head length and a 1/4 inch collar thickness. The adjustable depth collar allows the installer to set countersink depth repeatably without measuring each pass, reducing setup time and improving consistency across production runs or service tasks.

This countersink is suited for metalworking, fabrication, and maintenance applications where clean, accurately sized countersunk holes are required. The right-hand cut geometry and 90-degree included angle make it a standard choice for flat-head fastener seating in steel, aluminum, and similar materials. It is appropriate for use by machinists, fabricators, maintenance technicians, and skilled tradespeople working with hand drills, drill presses, or CNC machines. The No. 13 drill compatibility specifies the drill size this countersink is sized to work alongside.

Key Features

• Adjustable depth collar at 1/4 inch thickness for repeatable countersink depth settings
• 90-degree included angle with 45-degree centerline angle for standard flat-head fastener seating
• 3/8 inch cutter diameter and 3/4 inch cutter head length
• High speed steel construction for durability and cutting performance
• Right-hand cut geometry compatible with standard drill rotation
• Compatible with No. 13 drill sizing

Compatibility

Designed for use as an adjustable depth countersink for No. 13 drill applications in standard holemaking operations involving flat-head fastener preparation.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with holemaking tooling. Secure the workpiece firmly before operation and confirm the adjustable collar is locked at the desired depth before beginning each pass. Use appropriate cutting fluid or lubricant for the material being worked. Inspect the cutting edges for wear before use and replace if chipping or dulling is observed.
