Band Saw Blades

Match blade width and tooth configuration to the material and cut type: wider blades (1/2"+) are best for straight cuts in metal or resawing wood, narrower blades (<1/2") handle tight curves; choose coarser teeth per inch (TPI) for faster cuts in wood and lower TPI for thicker metal, and use bi-metal or carbide-tipped blades for harder alloys

Verify blade length, width, thickness, and tooth pitch/TPI to match your saw and intended cuts; consult your saw manual for the required blade length and recommended width, and pick TPI based on material thickness (lower TPI for thick stock, higher TPI for thin stock)

Carbon steel blades are economical for softwood and non-abrasive materials, bi-metal blades offer longer life and heat resistance for cutting metal and mixed use, and carbide-tipped blades are suited for abrasive materials or high-production use where extended blade life outweighs cost

Blade life varies widely—hours to months—depending on material hardness, feed pressure, cooling/lubrication, tooth set and TPI, and proper tensioning; cutting abrasive or hardened materials, improper feed rate, and inadequate cooling significantly shorten life

Keep blades clean of resin and metal buildup, maintain correct tension and tracking, use appropriate cutting fluid for metal, replace or sharpen blades when teeth become dull or damaged, and ensure guides and bearings are properly adjusted

Store blades coiled loosely or hung on wide hooks to avoid kinking, keep them dry and lightly oiled to prevent rust, and separate different tooth pitches or materials to prevent cross-contamination

Blade prices range from lower-cost carbon steel options under $50 to higher-cost bi-metal and carbide-tipped blades well over $100, with price influenced by blade material, tooth design, length, and intended application
