Wood boring auger bits

The auger bit has a helical screw blade for boring deep and large diameter holes into the all types of wood. It is one of the most common types of wood boring bits. Traditionally, it was used in a hand brace, currently the wood boring auger bits are made for use both in power tools and brace. Many companies like Irwin, Milwaukee, Bosch etc. make this tool. All auger bits are not same; they come in a variety of ‘patterns’ or shapes. These bits range in diameter from 1/4 inch to 1 inch. They are long than others bits which makes them nice for long or deep holes. So they can able to bore deep holes which are very smooth. The screw blade can also act as conveyor to remove shavings or debris from the hole. Different types and designs auger bits are available for boring holes. It consists of feed screw, cutting lip, flute, spur, twist, shank, and tang.

What is an Auger?

A wood auger is a drilling device which is used for making holes in wood. It includes a rotating helical screw blade to drill and remove the drilled out material. It may also have a guide screw on the tip to draw the bit into the wood with using less force.

Types of auger bits

There are different types and designs auger bits are available in the market for boring holes such as pole auger bit, Ship Auger Bits, Solid Center Auger, Spur Auger Bits. Each of the bits has unique designs to easily eject chips from the hole during drilling. According to twisting the wood boring auger bits are two types; single helical twist and double helical twist. The single helical twist has a solid center and one cutting twist whereas the cutting twist is wrapped around the solid center. On the other, the double twist also known as Jennings bit which is stronger and very fast chips cleaners. These bits range in diameter from 1/4 inch to 1 inch.

Can I use an auger bit in a power drill?

Traditionally, the auger bit was used in a hand brace, but at the present time the wood auger bits are also made for use in power drill. The auger bit with tapered square shank is suitable for brace while the straight-shank version is suitable for power drill. When auger bit is used in power drill, its speed should not exceed more than 600-700 rpm. All long wood auger bits feature 7/16″ adaptable hex shanks.

What are auger bits made of?

The auger bits are now made from higher carbon steel for more rigid and resilient properties. These bits are softer than the bits which are making from high speed steel. This soften property makes them popular for cutting wood. The drill bits are also made of Titanium bit, titanium nitride or titanium carbonitride coated, Cobalt, or Cobalt coated. The coated bits have more strength compare to their un-coating bits. High speed steel (HSS) is steel alloyed with cobalt, tungsten or molybdenum, or coating with titanium, black oxide, or carbide tipped.

Which drill bit is for Wood?

It is necessary to bore a hole in almost every type of woodworking project. Many things like medium, surface of the projects play an important role for drilling a hole. Since the wood is softer than metal, so the wood drill requires less force than metal.

Titanium and cobalt bits are useful for wood project. But they can be a little too strong for wood projects. So they shouldn’t be your first choice. In this case the bit has some slipping risk. On the other hand the coating of Cobalt and titanium will change the behavior of the Cobalt and titanium bit. The Titanium-coated drill bits have reduced friction which is best for hardwood, softwood, PVC, fiberglass and steel. But the price is comparatively high. Cobalt and cobalt coated drill bits are used for drilling hard metal and steel.

How do you drill through an auger bit?

An agar bit is designed to run very slowly and with minimal pressure, the RPM of which is usually around 600-700 during drilling.

How do you sharpen auger drill bits?

Wood auger bit can be sharpened. Titanium coated drill bits are coated with Titanium nitride which is gold in color. If these auger drills bits are sharpen then the coating will be affected. On the other hand Cobalt bit is an alloy material. When you sharpen an auger bit you have to be careful not to damage the bit.
