The Type of Drill Bit For Dowels

A spur point bit is the kind of drill bit that works best for drilling dowels. A wood bit or a dowel bit is another name for this tool.

In most cases, dowels are made of compressed wood. They are crushed to the point that they leave longitudinal grooves all over the sides. When the dowels are put, these grooves provide relief for the glue that is being used.

Glue must be applied to the surface of the dowel as well as the hole. When the adhesive penetrates the dowel, the dowel will expand somewhat. This compensates for the fact that it was previously compressed. That it may fit even more snugly.

Therefore, the hole should be half an inch.

Drilling in Dowel

Popular woods are strong to varying levels. But properly drilling in a dowel will increase the strength of the wood.

The difficult tasks of designing and accurate alignment may be accomplished with relative simplicity using a jig. Because dowel jigs operate as drill guides. The drill bits are also put into a metallic bushing or sleeve that is a part of the tool.

The bushing ensures that the bit remains in the appropriate location. It is in the middle of the component to be drilled. Also perpendicular to the edge that will be drilled.
