Excision Bi-Alfa WS Alu Band Saw Blade 62220003-2110 2110 x 20 x 0.9mm 3 TPI

Excision Bi-Alfa WS Alu band saw blade, 20mm wide, 0.9mm thick, 3 TPI, base code 62220003. It is listed in 29 lengths from 2110mm to 9340mm.

The maker describes the Bi-Alfa cobalt WS (Wide Set) Alu blade as having a wide kerf and an aggressive cutting angle, which it says gives more efficient chip flow, less binding and clogging and longer blade life on non-ferrous metals (manufacturer-stated).

Product Guide p17 shows a hook tooth with a positive cutting angle of 10°, described as suited to cutting solid, thick-walled tubes and higher-grade alloy material (manufacturer-stated). The listing gives the pitch as 3 TPI, a constant pitch: the maker describes this as the same distance from tooth to tooth and as very suitable for cross sections and non-ferrous materials (manufacturer-stated).

Key specifications

Selecting the right option

Start with the blade length your saw needs. The maker's method is to set the wheels about the middle of their adjustment range, measure the distance between the wheel centres and the radius of each wheel, and add pi times each radius to twice the centre distance (manufacturer-stated). Pick that length in the option selector: the part code is the base code, a dash and the length in mm. The maker says the TPI has to suit the thickness of the material being cut or blade life is dramatically shortened, and suggests aiming for 5 to 7 teeth in the cut (manufacturer-stated).
