Are Bi-Metal Blades Really Worth The Additional Cost?
Extended Lifespan: Bi-metal blades can last significantly longer, often up to three times longer, than conventional carbon steel blades. This reduces the amount of blade changes and downtime.
Superior Durability and Strength: The unique construction of a bi-metal blade combines a flexible spring steel body with a high-speed steel (HSS) cutting edge.
The HSS teeth are very hard, offering excellent heat and wear resistance, allowing them to maintain sharpness for longer periods. Their hardened teeth also allow you to cut through materials that might contain hidden metal objects like nails or staples without immediately dulling the blade, a major advantage for processing urban logs.
Versatility in Cutting Materials: While effective for general woodworking (softwoods and hardwoods), bi-metal blades excel in difficult conditions.
They are highly recommended for cutting reclaimed beams, kiln-dried lumber, knotty woods, and frozen woods.
Improved Performance: Bi-metal blades can handle higher band tension and cutting speeds, which translates to straighter, cleaner, and faster cuts, especially in tougher materials. They can also be resharpened multiple times, further extending their utility.
Although the initial purchase price of a bi-metal blade is higher than a carbon blade, their extended lifespan and reduced downtime mean they are more cost-effective in the long run.
