The early hand blades, power (machine) saw blades as well as bandsaw blades were all made from carbon steel. Carbon steel blades were unable to cut harder material such as die steel, alloy steels etc.
Introduction of high-speed steel (HSS) hand and power blades made it possible to cut harder material. In the 70s, bimetal blades were developed, which combined the good cutting ability of HSS teeth and good flexibility of carbon steel body.
Later developments were in the form of carbide tipped saw blades, whereas the more recent ones have coated teeth for special sawing applications as well as for higher sawing rates. It is Bimetal bandsaw blades, which have dominated sawing applications for nearly two decades and most development work is now concentrated on these type of saw blades.

How do I select a saw blade for my application?
A sawing application is defined by the type of material (its composition and hardness), its shape (round, square, I-section, L-section, pipe etc.) and its size.
The material type decides whether you can effectively cut it with carbon blade or HSS blade (or with a bimetal blade).
The shape and size decide the pitch (TPI) and the tooth profile of the saw blade to be selected. A tooth profile with positive rake provides higher penetration and gives higher cutting rate (productivity), but there is a risk of teeth ripping (stripping), if machine’s condition is not good (loose guide, vibrations, misalignment, incorrect tracking etc.). However, a
zero degree
rake or negative rake have more tooth strength and it reduces the risk of teeth ripping (stripping).
3-teeth rule, which is the basic rule of sawing, should always be applied. This states that - a minimum of 3 teeth of the saw blade should be in contact with the material during cutting. If not, you could experience teeth ripping (stripping) in the blade.

How do you ensure quality in Miranda saw blades?
Firstly, by using raw material steel from the best international manufacturers, who ensure excellent geometrical and metallurgical quality.
The manufacturing quality is ensured by our technology that can manufacture a world class saw blade and an effective quality management system (QMS). We are currently certified to ISO 9001:2000.

How do you guarantee the performance of Miranda saw blades?
Every Miranda saw blade, whether it’s a hand blade, a carbon blade or a bimetal bandsaw blade, is manufactured with appropriate technology and process control, which ensure the desired product quality. A saw blade’s product quality is measurable in terms of its geometricalparameters (correct length, correct width, smoothness of tooth profile, teeth sharpness, correct setting etc.) and metallurgical parameters (teeth and body hardness, carbide distribution, martensite structure, retained austenite etc.).
A saw blade’s actual cutting performance depends not only on the quality of the blade but also correct selection of the blade for a given application, machine condition, and machine settings.
If these conditions are not met, even a perfectly good blade could have teeth blunted or teeth ripped (stripped) or it could cut taper. Teeth ripping (stripping) in almost all cases results from poor machine condition or incorrect machine setting.
