“This is one great radial arm saw. I have been using my 12″ Original Saw for the past 7 years to build kitchen and bath cabinets and custom furniture. This saw has far exceeded my expectations with respect to performance, accuracy and overall operation. I have not had any repair items with the saw since I purchased it for our business. Any questions as far as setup or operation were promptly answered with a phone call. I really take advantage of this heavy duty radial arm saw’s 24″ crosscut capacity for cutting upper and lower kitchen cabinet sides and shelves, book case sides and shelves and other custom built-ins components. Making precision cuts with this saw is just as routine in our shop as the sizing of rough stock to length. This Original Saw Company radial arm saw is the best.”

12" Contractor Duty Radial Arm Saws

The Contractor Duty Series Wood Cutting Saws are an industrial rated radial arm saw that has the versatility to crosscut, bevel cut and miter cut. These saws are well suited for wood cutting up to a 3″ depth of cut, as well as cutting off 24″ wide panels for squaring shelving, doors and other similar applications. These machines are found in small lumber yards, custom cabinet shops, schools, contractor shops, crating departments or anywhere smaller material is being cut off, miter cut, bevel cut, sized or dado work is being done.

The Contractor Series Radial Arm Saws continue to be a workhorse with a TEFC motor and internal automatic brake and a durable powder coated finish. This radial arm saw has the best cut quality in its class and is a precise cutting machine with repeatable accuracy that you can depend on day after day for years to come. The machines are fully assembled and tested in our facility and then packaged with the legs boxed on the skid. This makes setup a snap. Simply lift up the machine and install the legs. Then run power into the electrical enclosure and install the saw blade of your choice.

There are several blade options for the Contractor Duty Radial Arm Saw.  These saws use a 12″ carbide tipped blade.  The options we carry are a 36 tooth and a 60 tooth blade for general purpose cutting.  We also have a 100 tooth blade for fine cross cutting.  Blades are sold separately from the saw.
