Tapped Hole Countersink Diameter at Nora Mattocks blog

Tapped Hole Countersink Diameter. The maximum countersink diameter shall be 1.08. On tapped holes the issue is that without a chamfered hole there is a possibility of a burr that will extend above the bearing surface. Before tapping, it is good machining practice to countersink. The symbol for a tapped hole depends on the standards used. Tapped hole shall be countersunk on the bearing face or faces. What is the tapped hole symbol? It is done before tapping to prevent a feather edge or burr on the tapped hole. For metric holes, the diameter symbol is replaced with an ‘m’. A countersink is dimensioned by specifying the diameter of the countersink where it meets the surface and the included angle. The counterbore depth will align the top of the screw head with the top surface of the part and will define a hole diameter that includes clearance between the fastener and the hole. However, you can change the hole type or hole. If the detected hole diameter does not match any of the entries on the list of pilot hole diameters, the hole is treated as a through hole (or tapped hole).
