In last part we know that tungsten carbide spade bits are used for rough boring wood holes with a centering point and two cutters, they have 5 top applications, and here we talk about the tips of using them.

 

The most common sizes of tungsten carbide spade bit are ¾“ and 1“ diameter, however some spade bits are available in ¼“ through 1-1/2“ diameters, and they are available in an extended length for hard to reach applications and deeper hole drilling, a stubby (or short) length for tough to reach applications and shallow holes. Or you can simply buy an extension as an add-on to your standard spade bit length.Powerful cordless or corded drills are ideal for spade bits – Some spade bits are aggressive, and best matched with a powerful drill. Here are some tips for using wood spade bits:

 

1.A spade bit is not the recommended bit for a clean finish hole. Spade bits should be used for rough holes that will not be seen. A forstner bit would be a better choice for a 1-1/4” clean hole. If you still want to use the spade bit for this application, we recommend leaving the good side up. The entry will have a better finish than the exit, however, it will not be perfect.

 

2.After the bit engages the wood, you don’t need to push – just pull the trigger and let the drill do the work. Great for overhead drilling.

 

3.A side handle on you drill helps you to better control and guide the tool, and helps you handle the torque that the bit requires

 

4.“Stubby” or short bits are available for tight quarters. Long bits are available for constant drilling outside your reach.
