Spade Bits - Dissecting These Bit by Bit

When it comes to boring drills, the spade bit is one of the most popular types of drills for wood. The spade bit came into being around 1968 and was invented by Irwin Tools. The tool is of a flat type and comes with a couple of sharp lips. Thanks to such a design, the bore hole material gets scooped out easily. There are attached spurs at the edge of the lips that gives a clean cut around the bore hole.

Even the roughest of holes can cleanly be cut with a spade bit. The process can also be performed easily using a spade bit since the bits can cause splintering while it enters and exists a wood piece. This process is called tear out. Some spade bits are made in a way that there are holes in their body. This helps pulling out cables via the bore holes in the ways. The shanks are pretty long so that the cable can be tied up using thin wire. The spade bit is a necessary tool when going in for designing intricate woodworks. However, understanding the various parts of a spade bit will help you understand the different functions and ways of the same.

Spade Bit Parts

• The center point in a spade bit is very sharp and is the main focal piece that keeps the spade bit from slipping away during the drilling process. In case the spade bit center is replaced using a screw tip, you need to put in the least of efforts during drilling. The main effort has to be for pushing a drill using the drawing through mechanism while the spade bit spins. In this kind of spade bit, called the self feeding bit, you need to stop the digging mechanism by force. It is difficult and needs practice.
• There are some self feeding spade bits that come with a center point along with thread cut along edges instead of a guide screw. There are still other spade bits that have a thread cut. Once this thread part in a spade bit meets the wood piece, the working becomes easier like it would be for a screw based spade but the difference remains in higher control.
• The lips of spade but take off material from bore hole bottom with the spinning mechanism of the spade but in while. The spade lips majorly used in all the cutting purposes of woods. The spurs on a spade bit are sharp areas or points that can circularly cut into wood during the movement of the spade bit. The resulting hole is very neat, and the wastes too are removed without much mess. There are some spade bits that come sans the spurs. The lips are at a slight angle so that the angles at the farthest corner too meet the wood closely. The spade bits result in causing rough holes since there is lack of enough precision. Spade bits come with hexagonal shanks. This is so because the cutting edges of a bit needs higher torque than it is required for other drill types. The cylindrical shanks spin along chuck jaws despite being very well tightened.
• Spade bits have a hole for pulling through all attached cables. These are called cable holes.
