Drill Bits for Wood
Many people are drawn to woodworking because it offers the opportunity to partner creativity with craftsmanship. Creativity drives the types of projects that craftsmen choose to tackle, while skill and experience inform them of such details as which drill bit for wood will deliver the best results.
Since drilling holes is something that is necessary in almost every type of woodworking project, the latter decision of which bit to use to do the drilling is sometimes as important as the very project itself.
What is an Auger?
While there are several different types of bits used to drill wood, the two most common are the spade bit and the auger bit.
Each has its rightful place in a woodworker’s shop, but many craftsmen are still confused about the differences between them.
Simply put, spade bits have more of a scraping edge than a cutting edge, so they scrape the wood to make the hole.
Spade bits are efficient and bore through wood quickly, but they do a poor job of clearing the wood chips out of the bore hole and they often fray the entry and exit holes, giving an untidy appearance to the project.
An auger bit, by comparison, has a sharp cutting edge that bores clean, precise holes for a smooth cut with a tidy finish.
Augers also have a deep, wide flighting that channels the cut pieces up and out of the hole, eliminating the need to periodically remove the bit and clean the hole.
To understand what is an auger, many people can easily visualize the types of augers used to dig post holes for fences or very extensive holes for oil wells.
The bits used in woodworking employ the same principles. Auger bits are useful in most any application where clearing the shavings or debris out of the hole is important.
This action allows for deep holes to be cut into or through a piece of wood without causing the bit to bind or get stuck.
Many wood auger bits also have a guide screw on the tip which serves to draw the bit into the wood, allowing the craftsman to use less force to get the bit through the hole.
Traditional woodworkers who specialize in hand-powered tools particularly value auger bits when using a brace to drill holes.
A brace is a manual tool that has a knob at the top and a U-shaped crankshaft that the woodworker rotates to drive the bit.
Auger bits for brace drilling make it possible for woodworkers to drill holes without needing to use a great deal of force
Best Wood Auger Bits
Choosing the best wood auger bits for your needs will depend on factors such as the width and depth of the holes you need to drill, how much speed matters to you and how long you expect the blade to last.
