Flat Wood Bits

Flat wood bits or spade drill bits have 2 main cutting edges, 2 cutting spurs and a centring point. Flat wood bits are not really popular in Germany, in contrast to their wide acceptance in Anglo-Saxon countries.
Flat Wood Bit
Flat drill bits are quite an old type of drill bit that can be used to very good effect over a range of applications. They are cheap compared with twist drills or auger bits, but the resultant hole is not as clean and the exit of through holes in particular is anything but splinter-free.
Because of the flat drill head and the very thin shank compared with the drill diameter, relatively little steel is needed in their manufacture. As a result they are light and justly popular with anyone who wants to optimise the weight of their toolbox. The simple cutter geometry allows even less experienced users to sharpen their own drill bits. The modern hexagonal bit shaft makes for fast drill bit changes. The optional extension will optimise the drill bit set that needs to be taken along on a job. Flat drill bits go with high speeds and are used in power drills and screwdrivers, whether powered or cordless.

Flat drill bits hold an added interest for any workman who needs to pull a cable through a pierced wall. The drill head has a transverse hole. Once the hole is drilled, a wire can be fed through this hole and pulled through when the drill bit is retracted. This wire can then be used to pull cables or pipes through the drilled hole.
Flat Wood Bits
These flat wood bits with 6.35 mm hexagonal bit shank are sharp and of good quality. We stock them in lengths of 152 mm and 400 mm. Further down the page you’ll find an extension that expands the application range of these spade drill bits. Also you’ll find a drill bit set that lets you save a few euros compared with buying the bits separately.
