Looking for an Extreme Heavy Duty Trauma Shear for industrial use and or Healthcare? Our ER LIFE ONE SHEAR is nothing short of amazing. It was able to successfully cut 12g stranded copper wire with a thick Nylon coating on the outside. Today we were installing a Amp Millimeter on our CO2 Laser engraver. This amp will allow us to dial in our power setting per various applications of materials. In order to install this we had to rewire the meter to the laser tube and power source. We chose 12g Stranded copper THHN for its ability to conduct high voltage and be able to string without conduit. Those who are not familiar with electrical or THHN; here is some more information. THHN stands for “Thermoplastic High Heat-resistant Nylon-coated.” THHN is a designation for a specific insulation material, temperature rating, and condition of use (suitable for dry and damp locations) for electrical wire and cable. More about this at https://en.wikipedia.org/wiki/Electrical_wiring_in_North_America Our shear did amazing at cutting this material with no issues. As you will see in the video it cuts multiple times with a crisp snap. This is due to the great blade registration and strong cenerbolt. One of the great things about the ER LIFE ONE SHEAR is the use of Bohler M390 steel. This steel has a high HRC Rockwell allowing it to penetrate softer metals without chipping. It has a superior edge retention over all the competitor in the trauma shear market as they use a soft J2 420 metal. That metal is the lowest grade in the industry and the same as household shears. Also with the pairing of a DLC (Diamond Like Carbon) coating; the metal is protected from the copper while cutting through the casing. This reinforce the steel and protects it from blade chips or damage. This coating is the best in the industry as Diamond is the Mohs marker for hardness and scratch resistance.
