What Sets Plug Cutter Bits Apart


Plug cutter bits are perfect for precise woodworking projects, thanks to their tight tolerances.

They leave a smooth finish, and they won’t tear or splinter your stock, making them ideal for any project requiring nice-looking results.

The bits come with sharp edges that keep their cutting force throughout the cutting process, so there won’t be any loss of power or accuracy.

They also minimize waste, thanks to their minimal removal of material.

Plus, the bits are long-lasting and can be used multiple times without needing to be replaced.

This all adds up to a great investment that delivers reliable, high-quality results that stand the test of time.

How Plug Cutter Bits Work

Plug cutter bits are special tools used to make round, tapered plugs or plugs with a large diameter.

They are specially designed to cut through hardwoods like oak or maple.

Plug cutter bits work by pressing downward and rotating around a pin within the bit.

The rotation allows the bit to cut a perfectly round shape, creating a plug.

This type of bit is especially useful for furniture joinery, because it allows the plug to fit perfectly in the hole without leaving unsightly gaps.

Plug cutter bits come in many sizes and shapes, so it is important to carefully select the one that will work best for your project.

Features to Look For

When buying a plug cutter bit, it’s important to check for features that offer the best value.

Look for bits made from strong, durable materials such as carbide, steel, or aluminum alloys.

Check for cutting geometry options like up-shear or down-shear designs.

Look for adjustable blade depth settings to help control the size of the plug holes.

Make sure the shaft size and arbor hole size matches the power tool you plan to use.

And look for bits that come with a lubrication coating to ensure smooth cutting and save you time and effort.

When to Use a Plug Cutter Bit

Common Applications

Plug cutter bits are a handy tool for a variety of different projects.

They are commonly used when joining two pieces of wood, whether at a 90-degree angle or a 45-degree miter.

These bits can also be used to create a symmetrical design or put a decorative edge on a project.

For example, plug cutter bits can be used to make renewel plugs to cover screws, or for creating column molding around furniture posts or windowsills.

Plug cutter bits are also useful for creating pocket holes, or to carve dowels or plugs for wooden jigsaw puzzles.

Plug Cutter Bits In Your Workshop

Plug Cutter Bits are great tools to have in your home workshop.

You can use the bit to make round cuts in wood for furniture or cabinets.

You can also use the bits to shape dowels or plugs to fit in special grooves.

Plug Cutter Bits are a great way to substitute for many other tools in your workshop.

The bits are perfect for cutting holes in thin material like pegboard and can be used to chamfer the edges of holes as well.

Plug Cutter Bits can even help you craft dowel holes for joining mitered corners.

With a Plug Cutter Bit, you can easily make precise round cuts that are perfect for any woodworking project.

Techniques and Tips

When using a plug cutter bit, it’s important to choose the right type of materials for your project.

Hard woods require a different type of plug cutter bit than soft woods.

When drilling, make sure your drill bit is correctly aligned to prevent your project from becoming damaged.

To reduce the risk of splitting the wood, use a slow speed while drilling.

Adjust the adjustable depth collar so that it’s set to the same size as the plug cutter bit.

Don’t rush the process and take your time as you work with the plug cutter bit.

For a more precise plug cut, make sure your drill press has a steady base and is adjusted to the right height.

Follow good safety practices and use safety equipment such as protective goggles and breathing masks.

What To Look For In A Plug Cutter Bit

Plug Cutter Bit Options

When choosing a plug cutter bit, it’s important to consider what techniques and tips you should focus on.

Forstner style bits are best for drilling uniform, clean holes, while spade bits are great for larger holes.

This lets you create a range of hole depths quickly and easily.

Corner chisels can help you reach tight corners and edges, whereas Forstner bits are ideal for drilling circles inside of materials.

Also, consider if you need a standard or specialty bit for your intended application.

High-speed twist bits are great for drilling hardwoods, while ceramic bits are best for drilling in softer materials like plastic.

Consider these tips and techniques when selecting the right plug cutter bit for your job.

Choosing the Right Plug Cutter Bit

When buying a plug cutter bit, there are several things to consider.

Durability is the most important factor: choose a bit made of high quality material, so it can handle tough projects and provide long-lasting use.

It is also important to consider the type of shank: either round or hexagon shaped.

The right bit size is a must, too; make sure it matches the diameter of the cork you are using.

Additionally, look for a well-designed cutting edge; the smoother the edge, the better.

Finally, consider getting a bit with a shank-locking set screw and an adjustable depth stop, for consistent and accurate results.

All of these elements come together to help you find the perfect plug cutter bit for your needs.

Brand Reliability

When shopping for a plug cutter bit, it’s important to consider brand reliability.

Quality and durable bits make all the difference in the woodworking world.

Grizzly, Bosch, and Porter-Cable are trusted brands for woodworking projects.

Each of these companies have well-known reputations for producing high-quality plug cutter bits.

Many experienced woodworkers prefer Grizzly plug cutter bits for their impressive craftsmanship.

Bosch also has a good reputation for reliable and durable bits.

Lastly, Porter-Cable is another popular choice due to its long-lasting durability.

With a bit of research, you can find the perfect plug cutter bit from one of these reliable and trustworthy brands.

Safety Measures and Precautions


When using a plug cutter bit, it’s important to be aware of common mechanical problems that can arise.

If your bit slips or won’t cut, tighten the knob on the collar securely.

If the bit appears to be worn out, try adjusting the depth of the bit to see if it helps.

If the bit gets stuck, turn the drill off and allow the bit to cool before attempting to remove it.

If the bit is still stuck, unscrew the knob on the collar and try pushing the bit out while rotating the drill.

If the bit still refuses to move, look for any obstructions within the bit before trying to extricate it from the wood.

Maintenance and Upkeep

It is important to maintain and take care of your plug cutter bit to ensure it is in proper working condition.

After each use, clean the cutter bit and make sure to remove any sawdust or debris.

Inspect the cutting edges and sharpen them if necessary.

Inspect the plug cutter bit for any signs of damage and replace any damaged parts.

Ensure that all parts are properly aligned and secured together.

Periodically, lubricate the cutter bit with oil or spray lubricant.

Store your plug cutter bit in a safe, dry area and keep it out of children’s reach.

Following these measures will help maintain and extend the life of your cutting tool.

Staying Safe

When working with a plug cutter bit, it is essential to take safety measures and precautions.

First, always wear appropriate safety gear like goggles, a face mask, gloves, and long sleeves/pants.

Additionally, ensure that the tool is secure by properly attaching it to a workbench or clamping it in place.

Also, make sure the workpiece is stable.

When the plug cutter bit is being used, stand firmly and put your weight on the tool in a downward motion.

Finally, be sure to turn off the drill when done and never reach under the cutter bit to retrieve the plug.

Following all of these guidelines will help keep you safe while using a plug cutter bit.


Buying Your Plug Cutter Bit

When buying a plug cutter bit, DIY enthusiasts should pay attention to its features, quality, cost, and compatibility.

It’s important to assess the type of wood you need to cut and choose a bit that matches.

Additionally, look for a bit that is suitable for your power tool.

High quality bits usually cost more but are made of hard-wearing material which will last longer than cheaper options.

Consider the cost-benefit, and if you are attempting a rare or unusual project, it might be worth the extra cost.

Make sure the bit is compatible with your power tool to avoid costly repairs.

Be sure to always check manufacturer instructions when buying and working with plug cutter bits.

Lastly, look around and get the best deal you can find!
