ASTM A387/A387M A387 K91560 Material Machining Technology
Chamfering and deburring can be achieved with the use of specially designed countersinks, reamers, or die grinders. When using these tools, it is important to ensure that the cuts are made at a gradual angle so as to not compromise the strength of the object. In addition, be sure to use ample coolant to keep the tools from overheating and reducing their effectiveness.
