Product Description
Extreme low friction diamond saw blades for gem cutting
Engineered for:
- Common steel qualities up to 1400 N/mm² tensile strength
- Non ferrous metals
- Cross sections up to approx. 100 mm (4”)
Superior, because:
Tooth tips of HSS M42 / material no. 1.3247
The hook tooth with a positive rake angle combined with a raker set, for easy tooth penetration and chip formation on larger cross sections. Cuts long chipping and tough materials without a problem. The STAR-PLUS Bi-Metal band cuts smooth and accurate.

Additional Information
Why so successful?
M 42
material no. 1.3247
hardness approx. 67-69 HRC
M 51
material no. 1.3207
hardness approx. 69 HRC, with high tungsten and cobalt content
Flexible:
The blade backer of our Bi-Metal Band Saw Blade consists of a special alloyed spring steel. Highly flexible at a hardness of about 50 HRC. The ideal basis for long fatique life and excellent cutting performance.
Hard and wear resistant:
Tooth tips made of hardened HSS-Steel in M42 or M51 quality.
Perfectly joint:
Both materials are undetachably welded together.
All advantages:
The high quality Bi-Metal band combines the flexibility of the spring steel backing with the enormous wear resistance of high speed steel. Each tooth tip of the finished band is of hardened HSS-steel, extremely durable for best performance.
Terminology
b = width of blade
s = thickness of saw blade
h = gullet depth
t = tooth pitch
a = rake angle
y = clearance angle
w = width of set
The right tooth for the right performance
Only correct choice of tooth forms allows efficient cutting with low vibration. Four basic types are available:
0 degree - Standard tooth = N
Designed for:
- short chipping materials
- light wall thickness
Data:
- rake angle 0°
- 4 to 18 tpi
Article groups:
100, 110, 420
Positive - Hook tooth = H
Designed for:
- long chipping materials
Materials
- large cross sections
Data:
- positive rake angle
- 2 to 6 tpi
Article groups:
100, 110, 421, 426, 427
0 degree - Variable tooth = K-0
Designed for:
- low vibration cutting
- - structurals
Data:
- rake angle 0°
- variable tooth pitch of 3/4 to 10/14 tpi
Article groups:
430
Positive - Variable tooth = K-POS
Designed for:
- low vibration cutting
- solid materials
Data:
- positive rake angle
- variable tooth pitch of 0,75/1,25 to 4/6 tpi
Article groups:
433, 442, 445 (K-V)
Constant or variable?
Constant tooth pitch The tooth distance is equally spaced. The number of teeth per inch (25,4 mm) denotes the tooth of the saw blade. | |
Variable tooth pitch The tooth distances vary within a group of teeth. The smallest and the largest tooth pitch denotes the variable tooth of saw blade. |
What groups and waves can cause.
Apart from tooth pitch and tooth form the exact set is essential for the performance of the sawblade. The correct clearance of back is achieved by the specific set for the cutting application. This is to avoid blade pinching, very important in problematic cutting jobs. Width and type of set are tuned to the cutting application:
Correct tooth pitch – optimum performance.
The choice of the right tooth pitch can be decisive to achieve the optimum performance to cut the relevant cross section. Choose either Standard tooth with constant tooth pitch or Variable tooth with unevenly spaced teeth. It is advisable to use Variable tooth to cut problematic workpieces to reduce vibrations.
