The YF100N-A electric screwdriver features an adjustable RPM setting and a selectable Soft Start mode. The tool also offers a selectable Multi Hit Mode for soft joint applications, along with programmable settings for angle and auto reverse. Engineered for high volume manufacturing applications the brushless motor design ensures durability and reduces the standard maintenance costs associated with brush type electric screwdrivers. The YF power tool is ESD certified, ensuring less than 1 Ohm at the bit tip. ESD management assures 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 YFC-35D controller. Model:YF100N-A ESD Drive Size:1/4"
