This high-performance and versatile utility/general purpose saw blade is suitable for cutting the widest range of most steels and non-ferrous metals, including bundled and solid materials of diverse shapes and sizes on all types of band saw machines. The M42 tooth profile is durable and of variable pitch for reduced vibration, composed of alloyed high-speed steel with 8% cobalt and 10% molybdenum. Always double check your machines blades specs! NOTE: The owner's manual of some woodcutting bandsaw may stipulate that it can cut metal, but woodcutting bandsaws can only cut non-ferrous metals, such as aluminum, brass, copper, etc.Cutting steel could damage your saw, due to the fact that blade speed on most woodcutting bandsaws (average 800 to 3500 fpm) this is not slow enough (40 to 300 fpm) for cutting ferrous metals (like steel). Trying to cut steel at woodcutting speeds will ruin the blade due to extreme heat produced due to the speed. Bi-Metal bandsaw blades can cut all types of woods and are especially ideal for hard woods, like oak, maple, walnut or cherry. Bi-Metal bandsaw blades are also most commonly used for metal cutting, like carbon steels, light alloy steels, mold steels, and tool steels. Below is a helpful guide to picking the best blade for your needs. Use the chart in the Customization to help you determine the best tooth count. 3/4" Blades General Purpose Cutting = 8/12N Small Thinner Materials = 10/14N Larger Materials = 6/10N - 5/8N Tubing = 8/12N - 6/10N
