<P> This is a high quality HSS-E countersink ideal for a range of materials including steel and aluminium.  A countersink is a tool that creates a conical impression onto the surface of material.  This conical impression shares the same name as the tool.  A countersink is used to seat a countersunk bolt or fastener of some kind.  The main reason to use a countersunk bolt or fastener is to create a flat surface so that nothing can get cuaght on it.  It is also widely used to lightly deburr holes or chamfer them . </P>
