Sawstop CNS175-SFA30 1-3/4 HP Contractor Saw with 30-Inch Aluminum Extrusion Fence and Rail Kit

Offering versatility and safety in the shop and stability and mobility on the job site, the SawStop Contractor Saw (model CNS175-SFA30) delivers the performance you need with the peace of mind only SawStop s patented safety system can provide. The safety system detects when someone accidentally contacts the spinning saw blade, and then stops the blade in milliseconds — resulting in just a nick on a SawStop saw instead of the devastating injury. This model includes a 30-inch aluminum extrusion fence and rail kit.

Maximizing Practicality, Precision, and Mobility

The SawStop 1.75 horsepower Contractor Saw is a synergy of mobility and precision. First, its heavy duty trunnion and cast iron table top ensure a steady and true cut, no matter the configuration. And with over 100 different potential configurations for the Contractor Saw, you can make this saw fit your needs.

The Contractor Saw features a well shrouded blade to improve dust collection and reduce airborne particulates. The shroud tapers to a 4-inch port for direct connection to a dust collection system. The zero clearance insert supports the wood throughout the cut and reduces tear-out and chip-out.

A Safer Saw

What if you could stop a saw blade and prevent a serious injury? That sounds like a really good idea.Today, that idea is protecting woodworkers in tens of thousands of SawStop table saws in North America and around the globe.

The SawStop safety system includes an electronic detection system that detects when a person contacts the blade. The system induces an electrical signal onto the blade and then monitors that signal for changes. It can tell the difference between a finger and a piece of wood as the human body has a relatively large inherent electrical capacitance and conductivity, which will cause the signal to drop when a person contacts the blade.

When contact is detected, a fast-acting brake stops the blade, with a heavy-duty spring pushing a block of aluminum (called a brake pawl) into the teeth of the blade to stop the blade from spinning. The teeth cut into the aluminum and bind, thereby stopping the blade in about 3 to 5 milliseconds — or 1/200th of a second.

How It Works

#1 -- Detect

• The blade carries a small electrical signal.
• When skin contacts the blade, the signal changes because the human body is conductive.
• The change to the signal activates the safety system.

#2 -- Activate

• An aluminum brake springs into the spinning blade, stopping it.
• The blade s angular momentum drives it beneath the table, removing the risk of subsequent contact.
• Power to the motor is shut off.
• All this happens in less than 5 milliseconds!

#3 -- Reset

• Resetting the saw yourself is easy. Simply replace the blade and affordable brake cartridge and your saw is operational.
• The entire reset process takes less than five minutes.

Other safety features include a main power switch with lockout key to prevent unauthorized users from turning on the saw and a large start/stop paddle with hands-free shutoff that can be stopped with your knee, allowing you to safely stop the blade even when both hands are busy.

The Risks

According to the Consumer Products Safety Commission, there is a table saw injury every 9 minutes, and 10 amputations every day in the United States. Even the most safety-conscious woodworkers are at risk of an accident. And when that accident happens, the consequences are life-changing: extreme pain and trauma, loss of income-earning abilities, and loss of the ability to pursue hobbies. It s time to protect yourself. The SawStop saw has saved thousands of fingers.
