The method for countersinking round holes into metal parts, particularly metal parts of narrow width, first produces a pilot hole by boring or punching. The dia. of the pilot hole is greater than the nominal dia. of the final hole, but smaller than the max. size of the cone-shaped hole...

The stepped design allows for easy transition from drilling to countersinking, making it a one-stop solution for creating countersunk holes in both metal and wood. The set is ideal for drilling holes in materials with a hardness of under 25 degrees, including aluminum, thin iron plates, ...
18.After boring, the holes may be slightly countersunk in order to insure a tight joint and the easy slipping of the pins into place. 19.That is to say, rivet holes in plates to be riveted should have the burr or sharp edge taken off, either by countersinking, by reamer, or set. ...
A spotface is basically a shallow counterbore. This technique is more common in metalwork than woodworking. What is the process of chamfering? Chamfering adds an angle to the top of the hole to remove the sharp edge. Like spotfacing, this is more common in metalwork, but can also be used...
