Maybe you’ve heard people\u00a0should never ever drill a hole with an end mill if there isn’t already a hole at the center for the chips to clear. Why can’t the \uc5d4\ub4dc\ubc00 <\/a>clear the chips? If the answer is no.\u00a0How can you\u00a0plunge with an end mill\u00a0to produce a pocket as done by drill bit?<\/p>

As the subtitle indicates, the two kinds of tools are significantly different. Firstly, they vary in tool geometry. End mill<\/a>\u2019s cutting part is wrapped around flutes, which are a bunch of helical grooves on side of \uc5d4\ub4dc\ubc00<\/a>s. Each flute is with a sharp edge at least. While you can\u2019t see this kind of component on drill bits cause they merely use the edges on its top area instead of lateral cutting edge to drill down and evacuate chips. Secondly,\u00a0End mill is more versatile than drill bit. End mills are devised for not only cutting\u00a0horizontally\u00a0on work piece but also primarily making a groove then broaching the whole hole based on the groove afterwards. Whereas drill bits\u2019\u00a0can be only applied for boring straight hole down to material. In a word, drill bit can\u2019t be replaced with end mill to accomplish milling operation. \u00a0<\/p>
