Buying Guide for Diamond Grit Jigsaw Blades
Material Compatibility
Choosing a diamond grit jigsaw blade depends heavily on the materials you’ll cut. If you’re working with extremely hard materials like porcelain, granite, or marble, blades with 30 grit diamond matrices such as the Bosch T130DG are most effective. For softer materials such as fiberglass or plastic, a blade with finer grit or a set like the FOCSTOL 46 grit pack works well.
Blade Design and Coating
Look for blades with an optimized design that limits heat and pitch buildup, which prolongs blade life and enhances cutting precision. Features like Perma-SHIELD non-stick coating (Diablo blade) help reduce friction and extend use tremendously. Bi-directional teeth ensure clean finishes on both sides of the cut.
Durability and Longevity
Vacuum brazing and advanced bonding technologies greatly affect durability by securing diamond grit to the blade substrate firmly. Carbide edges and brazing technologies, like those used in Bosch and Disston blades, provide significantly improved wear resistance and longer blade life. Consider these technologies if you need a blade for repeated or professional use.
Blade Length and Shank Type
Most blades come with a standard T-shank that fits the majority of jigsaws, but the blade length varies. Blades ranging from 3 to 4 inches are common for diamond grit types and allow for precise control when cutting hard materials. Always confirm compatibility with your jigsaw model.
Cutting Speed and Finish Quality
Diamond grit blades cut slower than traditional wood blades but offer superior finish and edge quality. For projects requiring clean edges in hard, brittle materials, diamond grit blades with finer grit and bi-directional teeth provide smoother cuts and less chipping.
