Complete reference for miter saw types, blade sizes, cutting capacities, bevel angles, and safety practices. Essential for trim work, framing, and woodworking projects.
Standard Miter Saw
Compound Miter Saw
Sliding Compound Miter Saw
Dual Bevel Sliding Compound
| Blade Size | Crosscut at 90° | Crosscut at 45° | Best For |
|---|---|---|---|
| 7-1/4" | 2x4 lumber | 2x3 lumber | Compact, job site portability |
| 8-1/2" | 2x6 lumber | 2x4 lumber | Light-duty construction |
| 10" (non-sliding) | 4x6 lumber | 2x6 lumber | General construction, trim |
| 10" (sliding) | 2x12 lumber (12" wide) | 2x8 lumber | Wide boards, shelving |
| 12" (non-sliding) | 4x8 lumber | 4x6 lumber | Heavy framing lumber |
| 12" (sliding) | 2x16 lumber (16" wide) | 2x12 lumber | Maximum capacity, production |
Note: Actual capacities vary by manufacturer. Always verify specs before purchasing.
| Tooth Count | Cut Quality | Best Applications |
|---|---|---|
| 24-32 teeth | Fast, rougher | Framing lumber, rough carpentry |
| 40-60 teeth | Balanced | General purpose, most trim work |
| 60-80 teeth | Very smooth | Fine trim, hardwoods, finish work |
| 80-100 teeth | Ultra-fine | Melamine, laminate, veneer |
Kerf Thickness:
| Corner Type | Miter Angle | Application |
|---|---|---|
| 90° corner (inside/outside) | 45° + 45° | Standard corners, picture frames |
| 120° corner | 30° + 30° | Hexagonal projects |
| 135° corner | 22.5° + 22.5° | Octagonal projects, bay windows |
| 45° corner | 67.5° + 67.5° | Acute angle joints |
Formula: Miter angle = (180° - corner angle) ÷ 2
Example: For a 90° corner: (180 - 90) ÷ 2 = 45°
Flat on Table Method (Compound Cuts)
Nested/Spring Method
Common Crown Angles (38° spring angle)
| Corner | Miter | Bevel |
|---|---|---|
| Inside 90° | 31.6° | 33.9° |
| Outside 90° | 31.6° | 33.9° |
What is a Bevel Cut?
A bevel cut tilts the blade relative to the workpiece, creating an angled edge rather than a square edge. The blade tilts; the wood doesn't move.
Common Bevel Applications:
Tip: For edge-joined boards (like table tops), 45° bevels create a larger glue surface and hide gaps better than square butt joints.

This miter saw guide provides essential reference information for DIYers, woodworkers, and contractors who need to make accurate angled cuts. Miter saws are among the most commonly used power tools for trim carpentry, framing, and furniture making, making it critical to understand the different types and their capabilities.
Whether you're installing baseboards and crown molding, building picture frames, cutting deck boards, or framing walls, the miter saw delivers fast, accurate crosscuts at precise angles. Understanding the difference between standard, compound, and sliding compound miter saws helps you choose the right tool for your projects and use it to its full potential.
This guide covers blade selection for different materials, common miter angles for various joints, crown molding techniques, and essential safety practices. With proper technique and the right blade, a miter saw can produce cuts smooth enough for finish work without additional sanding.
Having quick access to miter saw specifications and techniques helps you work more efficiently and produce better results. This guide consolidates information that would otherwise require consulting multiple sources.
