Description
- Manufactured from High Quality High Speed Steel (HSS)
- Commonly used for deburring and chamfering applications in metalworking.
- Deburring: Countersinks are designed to create a conical opening in a material, typically metal. The 60-degree angle allows for effective removal of burrs or sharp edges left after a hole has been drilled or a material has been cut. This is crucial for improving the overall finish and safety of the workpiece.
