This type of auger drill is ideal for digging a lot of large holes.

• The third type is the hand auger.

It uses standard sizes of earth auger drill bits for small tasks.

You can use it for gardening, drilling small-sized holes, or planting shrubs and little trees.

For industrial ground drilling, earth auger drill bits are attached to the machinery.

Earthmoving operators attach them to the mini loaders, skid steers, and excavators.

Some models of earth auger allow the user to change the drill’s diameter.

They feature snap-on extensions that let you switch between different diameters.

Other earth auger models have a gear reduction feature.

This versatility enhances the performance of your earth auger drill bits.

How Do Earth Auger Drill Bits Work?

Earth auger drill bits empower augers to screw the earth upwards.

With the help of earth auger drill bits, they can manipulate the soil away from the ground to create holes.

They can also be used to move the liquid around, remove drain blockages, or lift ice.

Earth augers can stand alone or be fitted as attachments to other machines.

• Small manual augers dig holes in the ground or drill wood surfaces.

Use the correct earth auger drill bits to ensure outstanding outcomes.

• Large earth augers come in handy for drilling the ground to search or extract water and oil.

They use a counterweight method to deliver more punch to the ground and dig more areas.

• Other earth augers can extract soil samples to know the acidity of the earth.

Some augers operate as a power tool to drill soil to prepare it for planting purposes.

Why Choosing the Right Earth Auger Drill Bits is Important?

Whether it is just gardening, drilling, emplacing fences, or setting poles, bits in different sizes got you covered.

What Makes Earth Auger Drill Bits Different?

Earth auger drill bits are not your ordinary accessory or tool attachment.

They are the powered version of the drill-boring bits you use to make holes.

While they work to make bigger holes, earth auger drill bits do something more.

They carry out the drilled material while drilling like a screw conveyor.

From being a humble tool for agriculture purposes, earth auger drill bits are used in various fields.

They come in various shapes and sizes to meet the needs of users.

Different auger teeth are available for specific digging jobs.

While the small handheld augers are still widely-used for farming purposes, they help in other small tasks.

The larger earth auger drill bits help to drill minerals and oils.

What Materials Are Used to Manufacture Earth Auger Drill Bits?

During the nineteenth century, bits were made from hot-rolled cast steel.

Today, earth auger drill bits are crafted from commercial-grade tool steel or stainless steel.

Tool steels are primarily used to manufacture cutting machines and hand tools.

They undergo heat treatment to enhance their working hardness.

It also increases the earth auger drill bits’ adaptability to a particular application.

The treatment influences the properties of the bits such as:

• hot hardness or strength
• tensile strength
• wear resistance
• application temperature

Tool steels are classified according to:

• composition (alloyed or unalloyed)
• application temperature (high-speed steel, hot work, or cold work)
• cooling agents (water, air, and oil hardener)

Hot work steel (alloyed) is best for application temperature of the surface is over 200 °Celsius.

Cold work steel (unalloyed) is ideal when the application temperature is 200 °Celsius.

High-speed steel (HSS) is a special class of hot work steel that works for application temperatures of over 600 °Celsius application temperature.

• HSS delivers three to four times higher cutting speeds.
• It offers a high breaking strength.
• It provides good grinding power.
• It gives the power grind ability to blunt tools.
• It is more wear-resistant.
• HSS can be coated with different coatings that lengthen the life of the bits.

Other metals used to make earth auger drill bits include carbides, carbon steel, cobalt steel, and polycrystalline diamond (PCD)

• Carbon steel is classified into high-carbon steel and low-carbon steel.

Low-carbon steel is cheaper but does not hold the edge well.

Bits made of this type of carbon steel needs frequent sharpening

High-carbon steel is more durable as it goes through the tempering and hardening process.

• Cobalt steel alloy is a variation of HSS with more cobalt-content.

This material holds its hardness at extreme temperatures and best for hard-to-drill materials.

• Carbides, especially tungsten carbides can drill any kind of material.

They are extremely hard and hold the edge longer compared to other drill material.

• Polycrystalline diamond or PCD is one of the hardest drill materials for bits.

It is made of layers of diamond particles with tungsten carbide support.

To ensure wear-resistance, earth auger drill bits are coated with:

• Black oxide
• Titanium aluminum nitride
• Titanium nitride
• Titanium carbon nitride
• Diamond powder

How to Change the Earth Auger Drill Bits?

Changing earth auger drill bits follows the same procedure as any type of bits you have.

For your handheld auger, place it on a stand or a strong surface.

Step 1: With a wrench, be sure to remove the spark plug first to prevent accidental start.

Step 2: Loosen the hex bolt or the chuck of the auger bit housing with the right tool.

Remove the auger bit carefully.

Step 3: Clean the housing area with a soft rag or compressed air.

Wipe the debris around the bit housing.

It should be clean before replacing the auger bit.

This ensures that the earth auger bit is positioned properly and performs well.

Step 4: Insert and slide the new bit until you get it sitting straight in the housing.

Tighten the hex bolt or the chuck into the new bit to keep it secure.

For towable augers, use the quick disconnect system to change the earth auger drill bits.

• Disconnect the hitch pin
• Lower the bit carefully out of its housing
• Insert the new bit into the housing
• Check if it sits straight
• Reconnect the hitch pin to secure it

To make sure that you have replaced the drill bits properly, let it run to see if it is not wobbling.
