[edit] Another type of counterbore?
Isn't the tool that creates the angled recess for the head of a "flat head screw" also called a counterbore? That is, I don't think counterbores are limited to just creating flat-bottomed holes.

- To me that's a Countersink, which creates an included angle of either 82 ° or 90 ° suitable for the under side of countersunk screws such as e and f in this section. — Graibeard 20:15, 26 January 2006 (UTC)

[edit] Distinct
There is definitely a distinction between a counterbore and a countersink. A counterbore has a flat bottom, perpendicular to the hole for the screw or bolt. A countersink, by contrast, is a conical recess for a flathead screw. --Dvortygirl 23:35, 15 September 2007 (UTC)
