M42 High Speed Steel

10Feb by Lori Balkus

High Speed Steel, categorized as tool steel, is commonly used to cut tool bits, power saw blades, and bandsaw blades. Tougher than its predecessor, carbon steel, HSS is more tolerant of higher temperatures without compromising on hardness. This property allows for faster cutting rates than high carbon steels and why it is named high speed steel. There are three categories of HSS: M2, M35, and M42 steel. Of the three, M42 is widely used in the metal forming industry because its chemical composition is specially engineered for high hardness and superior hot hardness compared to the more conventional high speed steels. Properties that make M42 the better choice …

501 Series Bandsaw Blade

29Oct by Lori Balkus

Structural materials are made up of different types of steel formed in a specific shape or cross-section, and to cut these types of materials requires a specific bandsaw blade. Knowing blade type and tooth pitch as applied to materials, specific shape, and size is helpful as well as being key to successful output. Whether carbon, carbide, or bi-metal, the various saw blade types all possess unique features for specific usage. Bi-metal saw blades are general-purpose workhorse saw blades considered a preferred blade for use on structural materials. The bi-metal has unique, coarser teeth with high wear resistance, making them durable and long-lasting. Bi-metal blades are made up …

Creating Bi-Metal Bandsaw Blades

17Sep by Lori Balkus

Bi-metal bandsaw blades, as their name suggests, are saw blades that are made of two metals that are welded together. One method of creating this type of blade is known as electron beam welding (EBW), which is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined together. The electron energy heats up on impact, melting the materials. Another method for creating bi-metal blades is with laser beam welding (LBW), a technique used to join multiple pieces of metal using a laser. EBW and LBW both help in creating high-speed steels: alloys that gain their properties from tungsten, …

Carbide Bandsaws and Blades

17Sep by Lori Balkus

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 …
