Tungsten Carbide Wood Working Drill BitsⅠ

Tungsten carbide wood working drill bits are used for drilling into wood and some plastics. The bit is normally black in color and the tip of the bit has a raised spur or sharp point. This is used, before drilling, to place the point exactly where you want to drill the hole and using a bit of force to push the point into the wood to stabilize the bit before drilling. This will also ensure, while drilling, that your bit goes straight into the wood without running around and damaging the wood. You can use a variable speed drill for these bits but make sure the drill is not on the hammer position else you will damage the wood and the tip of the drill bit.

Here we introduce some commonly used types of wood working drill bits as follows:

1.Brad-Point Bit: A brad-point bit is designed for boring into wood. The brad at the center of the bit tip helps position the bit precisely for accurate drilling and produces a clean exit point in the work piece. The flutes — grooves that wrap around the bit and channel away chips and dust — are extra-wide to remove more material.
