Heavy-Duty Radial Arm Saw for Precision Woodworking

Original Saw 22.5 In. 3 Phase Super Duty Radial Arm Saw

Product Overview

The Original Saw 22.5 In. 3 Phase Super Duty Radial Arm Saw is a large-capacity industrial woodcutting machine designed for demanding production environments. As the largest saw in Original Saw's Super Duty radial-arm series, it combines a 7.5 HP three-phase TEFC motor, variable-frequency drive (VFD) control, an 8-inch maximum cutting depth, and a heavy-duty T-slot metal table.

Built for facilities that require consistent cutting performance over extended operating periods, the saw can perform crosscuts, bevel cuts, miter cuts, and compound miter cuts. Depending on the selected configuration, maximum crosscut capacity ranges from 17-3/4 inches to 25-3/4 inches.

Manufactured in the USA, the machine is intended for professional woodworking operations such as manufacturing, prefabricated construction, truss and door production, timber-home work, and industrial crating.

7.5 HP TEFC Motor with VFD

At the heart of the saw is a 7.5 HP totally enclosed fan-cooled (TEFC) three-phase motor. The enclosed motor design helps protect internal components from dust and debris commonly found in woodworking environments.

The integrated VFD provides a controlled startup rather than immediately bringing the blade to full speed. Original Saw states that the VFD ramps blade speed over approximately 8 seconds and provides controlled braking in approximately 25 seconds. This approach helps reduce mechanical stress while also providing a more controlled stopping sequence.

Available three-phase voltage configurations include:

• 208V

• 230V

• 460V

• 575V

Because industrial electrical requirements vary, the correct voltage should be selected to match the facility's available power.

Large 22.5-Inch Cutting Capacity

The 22.5-inch blade size gives this radial arm saw substantial cutting capacity. It can cut material up to 8 inches deep in a single pass.

At a 45° bevel, the maximum cutting depth is 4 inches. The machine can perform:

• Crosscuts

• Bevel cuts

• Miter cuts

• Compound miter cuts

The actual crosscut capacity depends on the configuration selected. Original Saw currently lists maximum crosscut options of 17-3/4 inches and 25-3/4 inches.

Heavy-Duty T-Slot Table

The 22.5-inch Super Duty model uses a T-slot extruded metal table, distinguishing it from many of the other saws in Original Saw's woodcutting lineup.

The T-slot design allows compatible clamps and accessories to be positioned along the table. Manual clamps are included as standard, while pneumatic clamping systems are available as an upgrade for applications requiring faster or more consistent material holding.

The standard worktable height is 36 inches.

Controlled Carriage Movement

The saw uses a manual chain crossfeed combined with a hand crank for carriage control. This gives the operator direct control over blade movement across the workpiece.

An adjustable crosscut stop is also included, making it easier to establish repeatable cut locations when processing multiple pieces of material.

For higher-throughput operations, Original Saw also offers an electronic powered crossfeed option as an add-on.

Front Lower Elevation System

The front lower-elevation system places blade-height adjustment at the front of the saw frame. This makes it easier to adjust the cutting position during setup without reaching around the machine.

The adjustment is useful when preparing the saw for different operations such as crosscutting, beveling, mitering, or dado work.

Safety Features

Original Saw incorporates several features intended to improve operator control and machine safety:

Emergency Stop

The E-Stop immediately interrupts the electrical circuit and engages the braking system to bring the machine to a stop.

VFD-Controlled Braking

The VFD provides controlled startup and braking, helping the blade accelerate and decelerate more smoothly than a conventional direct-start arrangement.

HDPE Lower Guard

A full-coverage HDPE lower guard provides additional coverage around the blade area during operation.

Base Column Lock

The base column lock helps secure the saw's column during operation and setup.

Industrial Applications

The 22.5-inch Super Duty Radial Arm Saw is designed for environments where large volumes of material must be processed consistently. Suitable applications include:

• Industrial woodworking

• Manufacturing plants

• Timber-frame and timber-home production

• Prefabricated housing

• Truss manufacturing

• Door production

• Packaging and crating

• General construction-component manufacturing

• High-volume lumber preparation

Original Saw specifically identifies the machine as suitable for facilities capable of operating the saw for approximately 2–3 shifts per day, depending on the application and operating conditions.

Recommended Cutting Materials

The wood-cutting version is designed for:

• Solid wood

• Hardwood

• Softwood

• Wood products

• Plastic

The manufacturer lists the 22.5-inch Super Duty wood saw under its Plastic, Wood cutting category.

Note: This product should not be confused with Original Saw's separate 22.5-inch Super Duty Metal Cutting Radial Arm Saw, which uses different tooling and is designed for materials such as steel, aluminum, brass, bronze, copper, fiberglass, and other materials.

Product Specifications

The current manufacturer listing gives 1,100 lb and 73 × 51 × 53 inches as the product weight and dimensions. Crosscut, miter, and depth specifications vary by selected configuration, so the final machine configuration should be confirmed when ordering.

Optional Equipment

The saw can be configured with accessories to better match production requirements. Available options include:

• Pneumatic clamping systems for faster material securing

• Electronic powered crossfeed for assisted carriage movement

• HDPE table inserts

• Bolt-on enclosed table guard

• Dust shroud/collection equipment for applicable woodcutting setups

• Compatible measuring and extension systems

Original Saw's pneumatic clamping systems can be configured around the material size, shape, production process, and number of pieces being cut simultaneously.

Blade Selection

For general-purpose woodcutting, Original Saw recommends its 22.5-inch General Purpose Blade with 60 carbide-tipped teeth and a -5° hook angle. The blade is designed for applications involving wood, plywood, MDF, veneer, and laminated materials.

The blade is sold separately unless specifically included in the machine configuration or package being purchased.

Setup and Electrical Considerations

This is a large industrial machine that requires appropriate shop space, electrical service, handling equipment, and installation procedures.

Because the machine is available in several three-phase voltage configurations, the selected version must match the facility's electrical supply. Original Saw's documentation also indicates that these machines are built to order and shipped by LTL freight, with the legs removed from the machine for shipping and installation.

Electrical connection and initial commissioning should be performed by appropriately qualified personnel.

Safety Considerations

The 22.5-inch Super Duty Radial Arm Saw is industrial cutting equipment and should only be operated by trained personnel.

Before operation:

• Read and follow the machine manual.

• Verify that the correct blade is installed and properly secured.

• Keep guards in their intended operating position.

• Use appropriate personal protective equipment.

• Secure and properly support the workpiece.

• Keep hands away from the blade and cutting path.

• Verify the emergency-stop system is functioning.

• Keep the table, carriage tracks, and surrounding area free of debris.

• Disconnect power before servicing, blade changes, or maintenance.
