Advantages
Constructed from durable high-speed steel, this countersink delivers consistent cutting performance and wear resistance when working with metal materials. The 16mm diameter provides optimal sizing for standard hardware requirements in workshop environments. It enables smooth material removal to create clean screw recesses, preventing fastener protrusions and contributing to professional-grade assembly results.
Suitable for
Deburring drilled metal holes
Chamfering edges on metal workpieces

Professional metalworking and workshop applications
When it may not be suitable
This tool is not intended for drilling primary holes, as it is strictly designed for secondary operations such as countersinking and chamfering existing holes. It may also not be suitable for high-speed automated production lines requiring specialized multi-flute tooling.
Key specifications
Tool type: HSS countersink for metal
Diameter: 16mm
Material: High-speed steel (HSS)
How to use
Secure the metal workpiece firmly in a vice or clamp to prevent movement during operation. Insert the countersink securely into the drill chuck or toolholder. Align the tool centrally with the pre-drilled hole, apply steady and moderate axial pressure, and operate the tool at an appropriate low to medium rotational speed depending on the metal type. Use cutting fluid if necessary to reduce heat buildup and extend tool life. Clear away metal chips frequently to maintain precision and visibility.
What to consider before purchase
Verify that the 16mm diameter matches your specific screw head and countersinking requirements
Ensure your drilling equipment is compatible with standard shank toolholders
Check that your application involves metal materials suitable for high-speed steel cutting tools
Always wear appropriate personal protective equipment, including safety glasses and gloves, when performing metalworking operations. Inspect the tool for wear or damage before each use and maintain proper cutting speeds to ensure optimal results and longevity.
