Vernon CCH-CCH3120 Adjustable Depth Drill Countersink

Product Description

The VERNON CCH-CCH3120 is an adjustable depth drill countersink designed for holemaking applications requiring precise countersunk profiles. Built from high speed steel, this tool accepts a 5/16 inch drill and produces a countersink with a 5/8 inch cutter diameter and a 90-degree included angle. The 45-degree centerline angle and 1-1/4 inch cutter head length allow consistent, repeatable results across a range of materials. The 5/16 inch collar thickness provides secure depth adjustment, making this countersink well suited for metalworking, woodworking, and general fabrication tasks performed by machinists, maintenance technicians, and skilled tradespeople.

The CCH-CCH3120 is used wherever a clean, accurately angled countersink is required prior to fastener seating. It is appropriate for right-hand drilling operations on ferrous and non-ferrous substrates in production, maintenance, and repair environments. The adjustable depth collar allows the operator to dial in consistent countersink depth across repeated passes without re-measuring, making it a practical choice for batch work or field service situations where setup time matters.

Key Features

• Adjustable depth collar with 5/16 inch collar thickness for repeatable depth control
• 5/8 inch cutter diameter with 90-degree included angle for standard fastener seating
• Compatible with 5/16 inch drill for combined drilling and countersinking in a single pass
• High speed steel construction for durability across ferrous and non-ferrous materials
• Right-hand cut orientation suits standard drill press and handheld drill setups
• 1-1/4 inch cutter head length provides adequate clearance in typical countersink applications

Compatibility

Designed as a standard adjustable depth countersink compatible with 5/16 inch drill shanks for use in right-hand drilling operations across general metalworking, woodworking, and fabrication applications.

Installation Notes

Install in a drill press or handheld drill with the appropriate chuck size for the tool shank. Secure the adjustable collar at the desired depth setting before beginning operations and verify it is locked before each use. Always wear appropriate eye protection when operating cutting tools, and ensure the workpiece is firmly clamped or secured to prevent movement during cutting.
