20″ Metal Cutting Radial Arm Saws can cut 7″ deep in a single pass and has a crosscut capacity of 23″ or 31″, depending on your chosen model. Weighing in at 850 pounds, this saw will withstand years of industrial cutting. In particular, use this saw to easily cut through fiberglass, aluminum, steel, bronze, brass, and plastics. Join Radial Arm Saws with both Original Saw Company’s Saw Extension Tables and Saw Measuring Systems to create a complete cutting solution.  

We pride ourselves in manufacturing an American-made product. 

From the motor to the heavy cast iron arm, the 20″ Metal Cutting Radial Arm Saw is a solid machine for years to come. Its merits include the following:

  • 20″ Metal Cutting Radial Arm Saws are made from cast and ductile iron and features vibration-free operation.
  • Heavy-gauge, powder-coated steel forms the legs and frame.
  • With a TEFC (totally enclosed fan-cooled) motor and internal automatic brake, this radial arm saw has the best cut quality in its class.
  • In addition, this Radial Arm Saw has a T-slot aluminum extruded table. The aluminum extrusions house the manual clamps. The heavy duty table provides strength and support for bulky cutting.

Do you have the capability to run 3 phase power at your location? If so, this is the model you want. 3 phase power creates a smooth motor start-up. Most importantly, with no relays or capacitors inside the motor, there tends to be less maintenance and longer service life.

Recent updates to the 20″ Metal Cutting Saw include the following:

  • A start/stop button on the left front edge of the table supplies additional accessibility.
  • The E-stop became a standard feature. An E-Stop is a safety mechanism to shut off machinery in an emergency. This switch stops the operation of the Radial Arm Saw. Most importantly, it shuts off all potential hazards outside of the saw’s power enclosure.
  • Redesigned extended elevating cranks provide easy elevation.
  • Lastly, multiple table options are available.

This saw is perfect for cutting extrusions and profiles. They can make several kinds of cuts.

The Metal Cutter holds several advantages over other saws in the industry.

  • It is able to cut large sized material.
  • It can also cut a large volume of pieces at one time.

Extrusion companies, sign manufacturers, aluminum window and door manufacturers, hollow metal door operations, metal decking manufacturers, metal roof manufacturers, fenestration industries and the glass and the glazing industry frequently use our radial arm saws.

Original Saw Company offers three types of operation for Radial Arm Saws.


  • Manual Operation – Standard Radial Arm Saws are powered by the operator.  The operator pulls the handle and the blade moves forward radially to make the cut.  Manual operation is a standard feature on all Contractor and Heavy Duty Series Radial Arm Saws.
  • Hand Crank Operation – Hand Cranks are used instead of Manual Operation for better carriage control.  This operation is ideal for cutting large timbers, metal cutting applications, and heavy dado work.  Hand Crank Operation is available on 22.5” Super Duty Radial Arm Saws and all Metal Cutting Radial Arm Saws.
  • Semi-Automatic Operation – Add an electronic powered cross feed to a Radial Arm Saw for semi-automatic operation.  Push the button on the front side of the Radial Arm Saw and the blade will cut through the material and automatically return to the home position.  This operation is currently available on all Super Duty Series models and Metal Cutting Radial Arm Saws.


Our team has years of cutting experience.  Contact us for recommendations about clamping, feeding material, and complete automatic sawing packages.
