Precise drill holes are very important when it comes to working with building components or the fabrication of high-quality wooden parts. For example, holes in visible areas define the aesthetics of a piece of furniture and holes which are out of sight are crucial to the accuracy of the structure. For that reason, special precision wood drill bits must be used when working with wood. Wood drill bits have a pronounced centre point. The centre point helps to position the drill hole exactly. Spurs effectively cut clean through the fibres around the periphery of the drill hole. Metal drill bits are often used on wood, but because of their unsuitable cutting edge geometry – they result in less exact positioning and tear-out around the edge of the drill hole.
