Putting a screw recess into the base section

<p>The head of the screws should sink into the base section so they don&#39;t protrude. The screws I&#39;m using have a flat ridge, i.e. no taper. I&#39;m using a milling bit here to cut the flat-bottomed recess into already present holes. The rigidity of the milling and it&#39;s flat cutting end ensures the recess is accurately positioned.</p>
