SUCCESS: PERFORMANCE AND EXCELLENCE.

We continually challenge ourselves to produce and develop high performance band saw blades. Our experience
has been crucial to a first-class product. To make sure our customers get the best possible performance, we quality inspect our products during the development and manufacturing process. We refuse to deliver any of our
tools before intensive quality checks are conducted. State of the art quality assurance methods support us, to
ensure this consistent high level – from the word go.

BAND SAW BLADE GEOMETRY

TOOTH PITCH

Tooth pitch Zt (tpi) describes the number of teeth per inch (1 inch = 25.4 mm).
With band saw blades, a distinction is drawn between constant and variable tooth pitch.

TOOTH SET

During the setting process the teeth will be bowed side ways to free the blade from chip load. Depending on the application, we offer the following set patterns:

RECOMMENDATIONS FOR BLADE USE

Setting the tension of band saw blades
Eberle band saw blades are set with a tension force of 250-300 N/mm². Correct tension significantly affects the blade’s cutting accuracy. When blades are manually tensioned in sawing machines, the tension should be
checked after breaking-in and corrected where necessary. The Eberle tension meter can be used to set the optimum blade tension.
Contour sawing
The graph below depicts the optimum ratio between saw blade width and the radius to be cut. By adhering to this data, clamping or twisting of the blade can be avoided.

Band saw guides
Blade beam strength is responsible for accurate cuts. The closer the guides are to the materials being cut, the more accurate the cuts will be.
Blade break-in By breaking-in the saw blade, it is possible to achieve optimum durability. With uncoated saw blades, Eberle recommends breaking-in at a 40% reduced feed rate. If vibration occurs during break-in, a slight reduction in cutting speed will increase cutting pressure to stabilize
blade. Break-in should last approx. 15 minutes or cut a minimum of 300 cm2 of material.
Chip formation
The shape and color of the chips provide information about cutting pressure and thermal load on the saw blade.

Cooling lubricant
With most metal materials, cooling lubricant is indispensable. With Aluminum and Aluminum alloys, it also helps keep the gullets free of chips and achieve improved cutting surfaces. No lubricant is necessary for cast iron, brass and some non-metallic materials such as plastics, graphite etc.
Safety information
To avoid injury, protective gloves, safety goggles and protective shoes should be worn when using band saw blades.

CARBIDE AND BIMETAL MICROSTRUCTURE

Eberle uses carbide exclusively for its products in the carbide sector, which are characterized by their extreme shock and wear resistance. Sub micrograin types with a homogeneous microstructure are used.

The heat treatment of the HSS and the backing material is crucial for the hardness and shock resistance of the band saw blades. The quality of Eberle band saw blades is largely due to the size, number and distribution of the carbides.
