Excision Bi-Alfa Profile Band Saw Blade 62541203-4500 4500 x 41 x 1.3mm 2/3 TPI

Excision Bi-Alfa Profile band saw blade, 41mm wide, 1.3mm thick, 2/3 TPI, base code 62541203. It is listed in 16 lengths from 4500mm to 7890mm.

The maker describes Bi-Alfa Profile as a blade for vibration-susceptible cuts: vibration when cutting tubes, beams and profiles can damage a conventional blade and reduce blade life and cut area. The reinforced back edge of the tooth adds strength against vibration during interrupted cutting and protects the blade against tooth strippage, and the tooth tip is HSS M42 (manufacturer-stated).

The profile tooth has a reduced cutting angle of 6°, which the maker says adds to its resistance to vibration when cutting beams and tubes (manufacturer-stated). The listing gives the pitch as 2/3 TPI, a combi (variable) pitch: the maker explains that the first figure is the largest distance between tooth tips and the second the smallest distance within one group, and that a combi pitch widens the blade's application area and reduces vibration (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). For band speed, its chart for bimetal blades (Product Guide p31) runs from 80 to 90 m/min on construction and machining steel down to 15 to 25 m/min on heat resistant steels (manufacturer-stated).
