82 Degree Countersink 's FAQ
Q: 1.What is the purpose of a countersink?
+
-
A: A countersink is a conical hole cutting tool that is typically used to allow the head of a countersunk screw or bolt to fit flush with the surface of the surrounding material.
Q: 2. What is a countersink tool?
+
-
A: Countersinking is typically performed using a conical-shaped cutting tool called a countersink. This tool creates a tapered surface at the mouth of a hole. The primary purpose is to ensure a flat seating for screw heads, preventing them from protruding above the surface of the material.
Q: 3.What are the benefits of countersinking?
+
-
A: Prevents Surface Damage: Protruding screws can damage surfaces and materials over time. Countersinking ensures that fasteners sit flush, reducing the risk of wear and tear.
Q: 4.Why is it called countersink?
+
-
A: You "counter" the conical shape of the bottom of a flat-head screw. "Countersink" can also refer to a cylindrical depression to accommodate a cylindrical screw head (such as a socket-head cap screw) so the top sits below flush with the surface.
Q: 5.How deep can you countersink?
+
-
A: The depth of the countersink should be no more than 60% of the material thickness. Any deeper and you are risking the structural integrity of the material and part.
