There is no substitute for a metal cutting blade
A saw made specifically for metal cutting to be used
Metal cutting saw blades are employed to boost productivity. These ductile iron blades are simply best for professionals who cut common materials at almost every job site such as angle iron, sheet metal pipe, and steel plate found almost everywhere. Dedicated blades and saws engineered to perform the job are relatively new to the industry, so some fabricators may be unaware of the technology. Using a proper tool and a saw can bring in a loss of time and money. For high-end performance, it is recommended that a saw and a blade made specifically for metal cutting be used.
Choosing and Maintaining the Blade
There are several things to consider when purchasing metal cutting blades, the first of which is the application. Blades are designed for a specific material, such as aluminum, steel, or copper.
Blade Pitch and Design
The size of the work determines ductile blades pitch and design. The information is explicitly detailed on the packaging. In case of uncertainty, one can contact the company tech support.
Use Only Saw-Specific Metal Cutting Blade
It is highly recommended that a saw-specific metal cutting blade is employed for cutting through many structurals and solids. Although a circular saw blade is fairly versatile for several applications, it does have its limitations, and there are a number of applications mentioned on the packaging.
Preventing Premature Machine Wear
Buildup of materials on the cutting edge calls premature machine wear and attrition of the blade edge material. A professionally-built blade will avoid this buildup. One must specifically set the desired revolutions per minute (RPM) for metal cutting. It is important to note that a too high RPM for high cutting will lead to premature machine wear and attrition of the blade edge material. A slower speed will produce a clean and professional smooth cut.
Proper Application is Mandatory
Metal cutting blades should not be mounted on typical wood cutting saws. It is because the amount of torque developed during metal cutting could cause machine breakdown or result in operator injury or tool damage. The blade should be permitted to 'spin up', or get to full speed, before engaging the work. This allows the blade to work effectively and prevent tool damage.
Never use a dull blade
If the blade on a metal saw is too dull, it will place an unwanted strain on both the saw and the operator. A dull blade in a saw can be risky because of the additional force the operator must apply in order to make a cut. Moreover, it can also distort and damage the saw by overworking the motor.
One must buy a blade with the correct attributes for the work and saw. A metal cutting blade makes crosscuts safe, simple and accurate. Therefore, the next time you carry a project that involves cutting sheet metal, head to the hardware store and pick up a quality metal cutting blade that's right for the task. The savings in time and frustration will more than make up for the cost of the new cutting blade.
