    When do I need a flat drill bit? 

    Flat head drill bits are designed for fast drilling of large holes in wood. Utilising a centre point to locate the bit, the flat steel on either side will cut away at the wood quickly but roughly. Whilst they tend to cause splintering at the exit point, using a backing board when drilling will help to reduce this. 

    Their ability to create quick, large diameter incisions makes them ideal for pulling cables, wires and pipes through pierced walls, as well as for recessing screw and bolt heads into timber. They are best used with a powerful drill capable of supporting jobs requiring larger bits; flat drill bits move with high speeds and are suitable for both powered and cordless models.
