Tungsten Carbide Wood Working Drill Bits Ⅵ

In last part we know that as tungsten carbide wood working drill bits, countersink bits are used to counterbore holes, while bi-metal hole saws have a tungsten carbide edge as well as a diamond one. In this part we go on to introduce more types of wood working drill bits.

10. Plug Cutter

A plug cutter bores holes in wood, creating wood plugs for use in concealing recessed fasteners.When screw holes are drilled with carbide tipped countersink bits, the drilling creates a deeper hole enabling the screw head to be inserted below the surface. This allows a plug to be inserted into the piece and then sanded down creating a flat and clean surface.

11. Step Bit

A step bit is designed primarily for drilling in thin — up to 1/4 inch — metal, but will work with wood. The stepped design allows you to use a single bit to drill holes with different diameters. Often the diameter of each step is etched into the bit. You can also use this type of bit to deburr holes, clearing away waste material.
