Are you confused about bevel and miter cuts? Many woodworkers struggle to tell them apart, leading to mistakes and project delays.
A miter cut is an angled cut across the face or width of a board, while a bevel cut is an angled cut through the thickness of a board. Miter cuts keep the blade vertical but change the horizontal angle, while bevel cuts tilt the blade itself.
Let’s explore these essential woodworking techniques in detail. Understanding the difference between bevel and miter cuts will help you choose the right approach for your projects and achieve professional results every time.
Understanding Miter Cuts
Ever tried to make a picture frame but ended up with gaps at the corners? Using the wrong cutting technique can ruin your entire woodworking project.
A miter cut is made at an angle across the face or width of a board while keeping the blade perfectly vertical. This technique is commonly used for creating corner joints in frames, moldings, and trim work where pieces meet at angles.
Miter cuts are fundamental in woodworking and carpentry. When you make a miter cut, you’re changing the horizontal angle of the cut while maintaining a vertical blade position. Think of it as cutting across the wide face of a board at an angle other than 90 degrees.
Common Applications for Miter Cuts
Miter cuts shine in several applications. Picture frames are perhaps the most recognizable example – those perfect 45-degree corners that create a seamless frame require precise miter cuts. Crown molding and baseboards also rely heavily on miter cuts, especially when navigating corners in a room.
The most common miter cut is the 45-degree angle. When two pieces with 45-degree miter cuts are joined, they form a perfect 90-degree corner. This is ideal for:
Picture frames
Door and window casings
Crown molding
Baseboards
Box construction
Furniture trim
How to Make a Miter Cut
Making a miter cut requires either a miter saw or a table saw with a miter gauge. Here’s the basic process:
Measure and mark your cutting line
Set your saw to the desired angle (often 45 degrees)
Place the board flat against the fence
Make the cut while keeping the blade vertical
The key to successful miter joints is precision. Even a small error in the angle can result in gaps when pieces are joined. For best results, make test cuts on scrap wood and adjust as needed before cutting your actual workpiece.
Advantages and Limitations of Miter Cuts
Miter cuts create clean, professional-looking joints that hide end grain. They distribute stress evenly across the joint and, when done correctly, create strong connections. However, they do have some limitations:
Advantages
Limitations
Hide end grain
Require precise angle cutting
Create clean, seamless corners
Can be weaker than some other joints
Distribute stress evenly
May open up over time with wood movement
Visually appealing
Require glue and sometimes reinforcement
Understanding Bevel Cuts
Have you ever wondered why some edges on furniture slope instead of being square? That smooth, angled edge that catches the light just right is the result of a bevel cut.
A bevel cut is made by tilting the blade at an angle through the thickness of a board. Unlike miter cuts that change the horizontal angle, bevel cuts tilt the blade itself, creating an angled edge rather than an angled end.
Bevel cuts add a new dimension to woodworking by allowing you to work with the thickness of the material. When making a bevel cut, the blade is tilted at an angle less than 90 degrees relative to the table surface. This creates a sloped edge along the thickness of the board.
Common Applications for Bevel Cuts
Bevel cuts serve both functional and decorative purposes in woodworking. They’re commonly used for:
Edge treatments on table tops and counters
Creating watertight joints in outdoor projects
Decorative details on furniture pieces
Roof rafters and structural components
Door and drawer edges
Joining thick materials
Bevel cuts are particularly useful when you need to join pieces at angles other than 90 degrees. For example, when building a multi-sided box or container, beveled edges allow the sides to meet at the correct angles.
How to Make a Bevel Cut
Making a bevel cut requires a saw that allows the blade to tilt. Most miter saws, table saws, and some circular saws have this capability. Here’s the basic process:
Measure and mark your cutting line
Adjust the blade to the desired angle of tilt
Place the board flat on the saw table
Make the cut with the tilted blade
For a standard miter saw, you would:
Place the marked board face-up on the saw base
Adjust the bevel gauge at the rear of the saw
Tilt the blade to the correct angle
Make appropriate adjustments and complete the cut
Advantages and Limitations of Bevel Cuts
Bevel cuts offer unique benefits but also come with certain challenges:
Advantages
Limitations
Create strong joints for angled connections
More complex to set up accurately
Provide decorative edge treatments
Require saws with tilting blade capability
Allow for water runoff in outdoor projects
Can be dangerous if not properly secured
Enable construction of multi-sided objects
May require additional finishing
Compound Cuts: Combining Miter and Bevel
Have you tried to install crown molding only to find that corners are impossibly complicated? The solution lies in mastering compound cuts, where miter and bevel techniques work together.
A compound cut combines both miter and bevel angles in a single cut. This technique is essential for projects where pieces must join at corners that aren’t square, such as crown molding at ceiling corners or roof rafters.
Compound cuts represent the advanced application of cutting techniques, combining both the horizontal angle change of a miter cut with the blade tilt of a bevel cut. This creates a cut that angles in two directions simultaneously.
When to Use Compound Cuts
Compound cuts are necessary when joining pieces that meet at complex angles. The most common application is crown molding, which sits at an angle between the wall and ceiling. Other applications include:
Roof rafters and trusses
Gazebo and pergola construction
Multi-sided containers and boxes
Complex furniture joinery
Decorative woodworking projects
Making Compound Cuts with a Compound Miter Saw
A compound miter saw is specifically designed to make these complex cuts. Here’s how to approach a basic compound cut:
Determine both the miter angle (horizontal) and bevel angle (blade tilt)
Set the miter gauge to the required angle
Adjust the bevel tilt to the required angle
Place the workpiece firmly against the fence
Make the cut with both angles set
Many compound miter saws come with preset stops for common angle combinations, making it easier to create precise cuts for standard applications like crown molding.
Challenges and Solutions
Compound cuts are among the most challenging in woodworking. Here are some common issues and solutions:
Calculation Complexity: Use angle finders and digital protractors to measure existing angles accurately.
Test Cuts: Always make test cuts on scrap material before cutting expensive stock.
Reference Charts: Many compound miter saws come with reference charts for common compound angles.
Coping Alternative: For some applications like interior trim, coping joints can be easier than compound miters.
Choosing Between Miter and Bevel Cuts
Are you standing in your workshop, staring at your project and wondering which cut to use? This common dilemma has a logical solution based on your specific needs.
Choose miter cuts when joining pieces at corners while maintaining the same thickness throughout, like in picture frames. Use bevel cuts when you need angled edges or when joining pieces with different orientations, such as in multi-sided boxes.
Selecting the right cutting technique depends on several factors including the type of joint you’re creating, the look you want to achieve, and the structural requirements of your project. Let’s break down the decision-making process.

Strength Considerations
When structural integrity is important, consider these factors:
Miter Joints: Generally weaker on their own and often benefit from reinforcement with splines, biscuits, or dowels.
Bevel Joints: Can provide more gluing surface and better mechanical strength in certain applications.
End Grain: Miter cuts join end grain to end grain, which doesn’t glue as strongly as long grain connections.
Wood Movement: Both joint types are affected by wood movement, but in different ways. Miter joints may open at the tips, while bevel joints may show gaps along the seam.
Aesthetic Considerations
The visual impact of your choice matters too:
Visible End Grain: Miter cuts hide end grain, creating a cleaner look for visible corners.
Edge Profiles: Bevel cuts can create interesting light-catching edges and transitions.
Shadow Lines: Different cuts create different shadow patterns, which can enhance or detract from your design.
Traditional Expectations: Some projects have traditional expectations – picture frames typically use miter joints, not bevels.
Tools for Making Miter and Bevel Cuts
Do you have the right tools for your cutting needs? Using inappropriate equipment leads to frustration, wasted materials, and potentially dangerous situations.
A compound miter saw is the most versatile tool for both miter and bevel cuts. Table saws with tilting blades and miter gauges, hand miter boxes, and specialized jigs also work well for specific applications.
The quality of your cuts depends greatly on the tools you use. Let’s explore the options available for making precise miter and bevel cuts.
Miter Saws
Miter saws are purpose-built for making angled cuts and come in several varieties:
Basic Miter Saw: Makes miter cuts only (horizontal angle)
Compound Miter Saw: Makes both miter and bevel cuts
Sliding Compound Miter Saw: Adds a sliding function to increase cutting width capacity
Miter saws excel at quick, accurate cuts and are the go-to choice for trim work, framing, and general carpentry. They range from affordable homeowner models to professional-grade tools with laser guides and digital angle readouts.
Table Saws
Table saws offer versatility for both types of cuts:
For miter cuts, use the miter gauge that comes with the saw
For bevel cuts, adjust the blade tilt mechanism
For improved accuracy, consider aftermarket miter gauges or sleds
Table saws shine when cutting larger pieces that wouldn’t fit on a miter saw, or when making repeated cuts on multiple pieces.
Hand Tools and Jigs
Don’t overlook traditional and specialized options:
Miter Box: A pre-made guide for hand saws that ensures accurate miter cuts
Bevel Gauge: For marking and transferring angles
Shooting Board: A woodworking jig that helps refine miter cuts with a hand plane
Angle Jigs: Custom or commercial jigs that hold work at specific angles
Safety Considerations
Regardless of which tool you choose, safety should be your priority:
Always wear eye protection
Use hearing protection with power tools
Keep hands at least six inches from blades
Use clamps or hold-downs when possible
Support the entire length of long workpieces
Allow blades to stop completely before lifting them from cuts
Conclusion
Understanding the difference between bevel and miter cuts empowers you to choose the right technique for your woodworking projects, resulting in stronger joints and more professional results.
FAQ
What is easier to make, a miter cut or a bevel cut?
Miter cuts are generally easier to make as they only require changing the horizontal angle while keeping the blade vertical. Bevel cuts involve tilting the blade, which can be more challenging to set up accurately.
Can you make a miter cut without a miter saw?
Yes, you can make miter cuts using a table saw with a miter gauge, a circular saw with an angle guide, a hand saw with a miter box, or even a router with the right jig.
Why is my miter joint not closing properly?
Miter joints may not close properly due to inaccurate angle cutting, blade deflection, or wood not being perfectly square. Try making slight angle adjustments or using a shooting board to refine the cut.
Are bevel cuts stronger than miter cuts?
Bevel cuts can provide more gluing surface in some applications, potentially creating stronger joints. However, joint strength depends on many factors including wood type, glue, and reinforcement methods.
What angle should I cut for a picture frame?
For a standard four-sided picture frame, cut 45-degree miter angles on each end of your frame pieces. This creates perfect 90-degree corners when assembled.
Can all miter saws make bevel cuts?
No, only compound miter saws can make bevel cuts. Basic miter saws can only change the horizontal angle (miter), not tilt the blade for bevels.
What’s the difference between a compound cut and a double compound cut?
A compound cut combines one miter angle and one bevel angle. A double compound cut allows the saw to both miter and bevel in either direction, useful for complex crown molding installations.
How do I cut crown molding corners?
Crown molding typically requires compound cuts. The molding must be positioned upside down in the saw, with the bottom edge against the fence and the top edge against the base, then cut with both miter and bevel angles set.
