Keo 919-000-911 Carbide Countersink 3/16 in 60 Degree

Product Description

The KEO 919-000-911 is a single-flute solid carbide countersink designed for precise chamfering, countersinking, and deburring operations in metalworking and fabrication applications. With a 3/16 inch head diameter, a 60-degree included angle, and a 2-inch overall length, this tool delivers clean, accurate seat geometry in a compact form factor. The solid carbide construction provides the hardness and wear resistance needed for consistent performance across production or maintenance work. It is suited for use by machinists, toolmakers, and maintenance technicians working with ferrous and non-ferrous materials.

This countersink is intended for light-duty chamfering and deburring tasks where a small-diameter tool is required. The 3/16 inch shank diameter matches the head diameter, making it compatible with standard collet chucks and drill press setups. The 60-degree included angle is a common geometry used for fastener seat preparation and edge breaking on sheet metal, plate, and machined components. Its compact overall length of 2 inches suits applications with limited clearance or when working in a bench drill or CNC machine.

Key Features

• Solid carbide construction for high wear resistance and dimensional stability
• 60-degree included angle suited for standard fastener countersink geometry and chamfering
• Single-flute design provides clean cutting action on chamfering and deburring tasks
• 3/16 inch head and shank diameter for use with standard small-bore collet systems
• 2-inch overall length fits bench drill, drill press, and CNC setups with limited clearance

Compatibility

Designed as an OEM-style single-flute carbide countersink for use in standard collet chucks, drill presses, and CNC machines accepting a 3/16 inch shank diameter.

Installation Notes

Install in a collet chuck or drill chuck rated for the 3/16 inch shank diameter and ensure the tool is fully seated and secured before operation. Power down or de-energize the machine spindle completely before changing or inspecting the tool. Use appropriate cutting speeds for carbide tooling and the workpiece material to avoid chipping the cutting edge. Wear appropriate PPE including eye protection when operating cutting tools.
