The LF-Series is an economical brushless electric torque screwdriver. The durable power tool features a Swiss Maxon brushless motor, which reduces the standard maintenance costs for electric screwdrivers. The electric screwdriver is ESD certified, ensuring less than 1 Ohm at the bit tip. ESD management in power tools ensures product quality, cost savings and a reduction in overall ESD failures. Manufacturing engineers involved with microelectronic products are aware of the importance of controlling Electrostatic Discharge (ESD) failures. Lapses in preventing the occurrence of electrostatic discharge can affect production yields, manufacturing costs, product quality, product reliability, reputation and profitability. Requires a STC 40 or FT-30D transformer (power supply). Model:LF060P-A ESD Drive Size:1/4" F/Hex Range : 3 - 58.8 cN.m, 0.8 - 5.2 lbf.in, 1 - 6 kgf.cm. Tool Weight:15.5 oz.
