Band Saw Blades
AIMS Industrial stocks bi-metal band saw blades from Excision and Lenox for floor-standing and portable band saws — engineered blades for cutting structural steel, pipe, solid bar, tube and exotic alloys. Bi-metal band saw blades combine high-speed steel teeth with a flexible alloy steel backing, providing the edge retention of HSS with the fatigue resistance needed to survive the continuous flexing that band saw blades undergo in service.
TPI Selection — Matching the Blade to the Material
Teeth per inch (TPI) is the primary selection criterion for band saw blades, and the correct TPI for the material being cut directly determines cut quality, cutting speed and blade life. The general rule is to maintain 3 to 4 teeth in contact with the workpiece section at all times — too few teeth creates a hammering action that breaks teeth; too many teeth causes chip packing and blade binding. 6 to 8 TPI suits large solid sections, heavy-wall pipe and rough structural steel cutting where feed rate and throughput are the priority. 10 to 12 TPI is the general-purpose range for solid bar, channel section and medium-wall pipe — the most common selection for workshop band saws. 14 to 18 TPI addresses thin-wall tube, light sections and precision work where cut quality and finish are important.
Blade Width and Length
Blade width determines the minimum radius the blade can cut — narrower blades cut tighter curves; wider blades are more rigid for straight cutting. Floor-standing band saws typically use 3/4-inch, 1-inch or 1.5-inch wide blades. Portable bandsaws use narrower half-inch or 5/8-inch blades. Blade length is machine-specific and must match the wheel centres and throat depth of the particular saw. AIMS stocks replacement blades across metric and imperial sizes for common machine types.
Material-Specific Blade Grades
Standard bi-metal blades from Excision and Lenox suit mild steel, structural steel and general metal cutting. Stainless steel benefits from variable-pitch blades that reduce harmonic vibration and heat generation in work-hardening materials. For titanium, Inconel, hardened tool steel and similar difficult-to-machine alloys, cobalt-enhanced M42 grade tooth tips provide the cutting edge retention needed for productive cutting without premature tooth dulling. Aluminium and non-ferrous materials require larger gullets and coarser TPI to prevent chip packing. Using the correct blade grade for the material not only improves cut quality but significantly extends blade life — a blade running in the wrong application will dull quickly and produce a rough, burred cut face.
