16" & 20" Super Duty Metal Cutting Saws

Super Duty Metal Cutting Series…  The Ultimate Workhorse of the Industry

The 16″ & 20″ Super Duty Metal Cutting Series are capable of operating 2 to 3 shifts per day in an industrial setting.  They can do several types of cutting applications including cross cuts, miters, bevels and compound miter work.  The massive 850 pound machines are constructed of cast and ductile iron.  This creates a vibration free operation. The series excels with a durable, powder coated finish.

Super Duty Metal Cutting Saws are much more than radial arm saws.  When paired with optional equipment, they are a platform for a wide variety of cut off work.

How Do You Operate These Saws?

We offer two types of operation for Super Duty Metal Cutting Saws.  On a standard machine, the operator powers the manual radial arm saw.  The operator pulls the handle and the blade moves forward radially to make the cut.

The other option is a semi-automatic saw.  An electronic powered cross feed is added on the machine to make it semi-automatic.  With the push of a button, the blade will cut through the material.

With years of experience in metal cutting, we can assist you with choosing a machine for your application.  Ask us about clamping, feeding material, and complete automatic sawing packages.

******Please note that the saw pictured in the video has an electronic powered cross feed and pneumatic clamps.  Neither of these options come standard on the saw, but can be added.

What Can This Radial Arm Saw Cut?

Metal Cutting Radial Arm Saws can cut materials such as aluminum, steel, brass, bronze, plastics and fiberglass.  They can make several kinds of cuts.  For example, the Metal Cutting Radial Arm Saw will cross cut, miter, bevel and do compound miter work.

16″ saws have a maximum cross cut of 32″ and will cut 5″ deep.

20″ saws feature a 31″ cross cut and a depth of cut of 7″.

Who Uses A Metal Cutting Radial Arm Saw?

This Metal Cutting Series is generally found in extrusion companies, sign manufacturers, aluminum window and door manufacturers, hollow metal door operations, fenestration industries and the glass and glazing industry.  The Metal Cutter holds several advantages over other saws in the industry.  It is able to cut large sized material and it cuts a large volume of pieces at one time.

What Kind of Blades Should I Use?

Blade Options for 16″ Metal Cutting Saw:

  • 100 tooth carbide tipped blade for nonferrous cutting
  • 120 tooth carbide tipped blade for cutting plastic
  • 300 tooth HSS, generally know as high speed steel, for friction cutting steel

Blade Options for 20″ Metal Cutting Saw:

  • 120 tooth carbide tipped blade for nonferrous cutting
  • 120 tooth blade for fiberglass cutting
  • 300 tooth HSS, otherwise known as high speed steel, for friction cutting steel

Do You Need Test Cuts?

Are you unsure if this machine can cut your material?  Ask about sending in a material sample to Original Saw.  We will cut your material on our shop saw and video the process.  After that you can review the videoed test cuts before you purchase.  Send us an email at customerservice@originalsaw.com or call at (800) 733-4063 to get the process started.

Advice on Cutting Non-Ferrous Materials:

Cutting non-ferrous material such as aluminum, copper and soft brass is done effectively on the Original Saw Metal Cutting Series. Above all, blade choice is an important factor.

First, consider the wall thickness of the material.  Most of the time extruded aluminum is being cut. If the wall thickness is under 1/8”, choose a high speed steel blade with approximately 250 to 300 teeth.  On the other hand, if the wall thickness is 1/8″ or greater, use a carbide tipped non-ferrous blade with a negative 5 degree hook.  Using this type of blade will lower the chance of the blade grabbing the material and will  provide a smooth finish.

Secondly, consider the stiffness and shape of the extrusion.  If your extrusion has a thin wall with a flat area, flex may occur during cutting.  In addition, there is a chance the wall may chatter during cutting.  This can cause the carbide teeth to chip or break if the material is too thin.

Thirdly, in most non-ferrous cutting applications we recommend a mist coolant system The mist coolant system will extend blade life and cut quality will be improved. Not using a mist coolant will allow the blade’s gullets between the teeth to “clog up” with material.  This will require more frequent blade sharpening.

To summarize, look at the wall thickness, stiffness and the shape of the extrusion.  Equally important is choosing the proper blade and considering a mist coolant system.  This will result in quality cuts.

Advice on Cutting Ferrous Material:

Cutting ferrous material (steel) can also be done quickly and effectively on Original Saw Metal Cutting Series machines. Material up to 8 gauge can easily be cut with our high speed steel blades. These blades, which run at 3400 RPM, are friction cutting blades.  They melt the material rather than cutting it.

With this type of cut, the advantage is speed over cut quality. The cut is very accurate, however, there will be a slight burr because of the friction cutting action.  Material thickness, speed of the carriage and the type of material are factors that affect the burr size.

Most importantly, mist coolant on ferrous material cutting is prohibited and will make the burr size much larger.
