Bimetal Bandsaw Blades
The Roentgen range of Bimetal Bandsaw Blades provides comprehensive coverage of the blade widths, tooth geometries and pitches required to address the broad spectrum of metal sawing applications and are available in M42, M51 or Matrix2 tip alloys.
Bimetal band saw blades are based on a fatigue resistant high alloy steel backing strip with around 4% chromium content. This formulation ensures that the blade can withstand the severe mechanical stresses exerted by modern high production rate band saw machines. On the backing strip there is an electron beam welded HSS cutting edge through which the teeth are milled. The subsequent tooth setting, hardening and tempering operations ensure that the finished product will provide straight, burr-free and long-life cutting performance to satisfy even the most demanding of saw cutting applications.
This gives the choice of high hardness and wear resistance or high toughness and impact resistance. The comprehensive range of tooth pitches in both variable and regular form together with a choice of cutting face angles make it possible to provide a bandsaw blade specifically manufactured to satisfy all customer needs.
Bi-Alfa Cobalt M42
The high wear resistance of the Bi-Alfa Cobalt M42 results from the very hard and evenly distributed carbides in the tooth tips, formed during the hardening and tempering process, reducing wear rates at high sawing speeds. The saw blade can withstand the considerable flexing stresses, tension and blade guide pressure present in modern saw cutting machines.
Bi-Alfa Cobalt M51
Manufactured with an alloyed steel backing of about 4% chromium content and has an HSS M51 cutting edge. Due to the high cobalt and tungsten content of the cutting tips the bandsaw blade has high thermal and mechanical wear resistance. Recommended for cutting nickel based alloys, titanium and stainless steel and suitable for extreme cutting jobs.
Bi-Alfa Matrix2
Wear resistance at high temperatures is achieved by a high cobalt content. A precisely controlled heat treatment process optimises hardness and toughness for interrupted cutting applications, particularly of hollow sections.
Bi-Alfa Master
Harnesses the benefits of "triple chip" tooth geometry, widely recognised as the optimal form for production sawing. The teeth are CBN precision ground to form a chamfered high tooth and a pair of lower finishing teeth. Cutting faces are ground parallel to the back edge ensuring absolutely straight cutting while high cutting rates can also be achieved without compromising blade life or cut finish.
Bi-Alfa Cobalt WS
The WS Profile (Wide Set) band saw blade has a wider Kerf to create more clearance through the cut. The wider cutting channel helps to prevent the blade from binding and stalling in the cut, a common problem when cutting structural steels with high tension.
Bi-Alfa Cobalt RP
An extension of the highly successful Bi-Alfa M42 range of sawblades, the tooth shape has a cutting angle of 16 degrees without any loss in tooth strength. This aggressive tooth form is ideal for cutting hard materials, improving chip flow and blade life.
Bi-Alfa RP Master
Combines the precision sawing capabilities of the Master range with the aggressive cutting angle of the RP tooth profile, providing fast and square sawing together with an excellent cut finish, even on the most difficult-to-cut materials such as heat resistant steels, titanium, stainless steel, exotic nickel based alloys and super alloys.
