Carbide Bandsaws and Blades

Carbide Bandsaw Blades are derived from the carbide saw, a name that originated from a circular saw blade with silver soldered carbide tips. Other names include cold cut, cold circular, cold cut-off, and circular cold saws. The carbide blade nearly replaced solid or segmented high-speed steel (HSS) blades since carbide is much harder than HSS. HSS blades use coolant to keep the surface from over-heating, but the carbide circular saw has a unique geometry of teeth that allows for heat developed during the cutting process to be transferred to and then carried away with the chips. The most common type of carbide …

Ductile Iron

Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spherulitic graphite cast iron, and SG iron, is a type of cast iron. Ductile iron is part of a group of materials that can have a wide range of properties through control of micro-structure. The common defining characteristic is graphite. Ductile iron received its name due to the creation process. The graphite is nodule form rather than flake, like in grey iron. The sharp shape of the graphite flakes inhibit cracks and provide enhanced ductility, hence ductile iron. While most varieties of cast iron are brittle, ductile iron has …
