Finding the Best 20-Inch Diamond Blade for Cutting Stone
Choosing the right diamond blade for cutting stone can feel overwhelming. There are many options! This guide helps you find the perfect 20-inch blade for your needs. We’ll cover what to look for, what makes a good blade, and how to use it safely.
Key Features to Consider
- Blade Diameter: Make sure it’s exactly 20 inches. The diameter determines the size of cuts you can make.
- Segment Height: This is the height of the diamond segments on the blade. Taller segments are usually better for tougher materials, but they can also be slower.
- Segment Type: Different segment shapes (e.g., turbo, continuous rim) offer various cutting speeds and performance levels. Turbo segments are usually faster for softer stones.
- Bond Type: The bond refers to how firmly the diamonds are held in the blade. A harder bond is better for hard stone, while a softer bond is better for softer materials.
- Arbor Size: This is the hole in the center of the blade. Common sizes include 1 inch and 2 inches. Make sure it fits your saw.
- Maximum RPM: Every blade has a maximum speed. Never exceed this speed! It’s printed on the blade.
Important Materials and Construction
Diamond blades are made of a steel core with diamond segments attached. The quality of the steel affects the blade’s durability. High-quality steel resists bending and breaking. The diamonds themselves determine how well the blade cuts. Higher-quality diamonds cut faster and last longer. The bond holding the diamonds also impacts performance. A poor bond means diamonds fall out quickly, ruining the blade.
Factors Affecting Blade Quality
- Diamond Quality: Higher-quality diamonds cut faster and last longer. Look for blades that specify the diamond quality.
- Segment Density: More segments usually mean a faster cut, but it might also wear down the blade quicker.
- Manufacturing Process: Blades made with precise manufacturing processes are generally more durable and perform better.
- Steel Core Strength: A strong steel core prevents bending and breakage, extending the blade’s lifespan.
- Bond Strength: A strong bond keeps the diamonds securely in place, preventing premature wear and tear.
User Experience and Use Cases
A good 20-inch diamond blade should cut smoothly and efficiently. It shouldn’t vibrate excessively. Excessive vibration can damage your saw and is dangerous. The blade should also last a reasonable amount of time before needing replacement. Different blades are suited to different materials. Some are ideal for granite, while others are better for softer stones like marble. Always check the blade’s specifications to ensure it’s compatible with the material you’re cutting.
