Use: The spade drill bit is normally
used for drilling wood. Especially where a large, clean hole
is desired. The center point guides the bit, the spurs on the
edge cut the wood fibers and the edges scrape off the wood, forming
a hole. This bit is especially good for drilling holes that
will receive dowels to conceal screws or other hardware. The
spurs keep the bit from tearing out the surrounding wood.
These bits tend to dull fairly quickly but are inexpensive.
