Buying Guide for Circular Saw Blades for Angle Grinders
Selecting the best circular saw blade for your angle grinder depends on several critical factors to match your cutting needs and ensure safety and effectiveness.
Blade Diameter and Arbor Size
The standard for angle grinder blades is often 4-1/2 inches diameter with a 7/8-inch arbor hole. Verify your angle grinder’s specifications, as some blades include reduce rings (commonly 5/8 inch) to fit multiple arbor sizes for versatility.
Number and Type of Teeth
Blades with 40 teeth are typical for woodworking, providing a balance between smooth cuts and efficient material removal. Tungsten carbide or carbide-tipped teeth significantly extend blade life and maintain sharpness through heavy use. Fewer teeth generally mean faster but rougher cuts, while more teeth produce smoother finishes.
Material Compatibility
Choose a blade specifically designed for the materials you will cut most often—wood, plywood, plastic, drywall, or composite materials. Some specialty blades also handle metal, stone, or tile, but ensure your blade’s design matches your project materials for safety and performance.
Kerf Thickness
Thinner kerf blades remove less material, reducing waste and requiring less power from the grinder. They also provide smoother cuts but may be less durable. The 0.07″ (1.8mm) kerf seen in many blades strikes a good balance.
Durability and Safety Features
Look for blades constructed with hardened steel and carbide tips. Surface treatments like chrome plating add corrosion resistance and increase lifespan. Assess if the blade design minimizes heat buildup to prevent warping during extended cutting sessions.
RPM Rating and Heat Resistance
Blades must support your grinder’s maximum RPM, commonly around 13,000 to 13,500 RPM for 4-1/2 inch models. A blade that heats excessively can degrade cutting quality and safety. Blades engineered to reduce overheating will last longer and maintain consistent performance.
Pack Size and Value
Consider how many blades you receive per package, especially for frequent use or multiple projects. Multi-packs often provide cost savings while ensuring you have backups when a blade dulls.
