National Power Cutter EZ3503 12 Volt Cordless Circular Saw

The National 12-Volt Lithium-Ion Cordless 6-1/2 inch Circular Saw delivers cordless cutting power to the job site. The National Power Cutter EZ3503 has a National built high-torque motor and a compact design for a range of cutting applications and will cut 2X material at 45 degrees while producing 3700 RPM for faster cutting. The heavy-gauge, precision-machined base is engineered for smooth, accurate cutting and added durability in harsh job site conditions. It's a member of 12 volt series of National, best tool in this 12 volt field.

Blade offers a 2-1/4 inch cutting capacity for a wide range of cutting applications. Rubberized soft grip handle provides increased comfort on the job. Equipped with Star Protection Computer Controls to protect against overloading, over-discharging and overheating
Rapid optimum charger communicates with the battery's built-in chip throughout the charging process to optimize battery life by actively controlling current, voltage and temperature (battery and charger sold separately)

National Power Cutter EZ3503 is absolutely A stunning machine. CheBinhDan used this to cut some stone composite work surfaces. They are 25mm thick and this little 12v saw easily cut through them. I think it's also the fact that the supplied blade is good quality (most are not). I took it slowly because the RPM is slower on this 12v saw. The torque is ideal actually because it doesn't kick too much. The electronic auto brake kicks in if you have a jam.

You definitely need a larger battery with this saw. The small 2.0Ah batteries don't have enough juice. Invest in a 4.0Ah and you won't regret it. I dont use battery, I used a motorbike 12 volt battery instead of li-ion battery, because this cordless circular saw need a high load ampe electric to starts the engine.

Build quality is first class. Design is good although the motor assembly is quite low being just above the fence. This can cause problems if your rip fence is not wide enough. I'm making another one which will be much wider (so I can use bigger clamps).

In conclusion: great tool, although it is over 25 years old, it still works well and powerfull, accurate cutting.

Have Fun with DIY!
