1/4-in x 3-in Hex Magnetic Bit Extension

Spyder bit holders are impact rated for demanding high torque 1/4-in impacting applications. A powerful magnet retains fasteners for enhanced driving accuracy and one-handed ease of use. These heavy duty tool steel bit holders are engineered for use in impact drivers, and can also be used in standard rotary drills with a 3-jaw chuck. A low profile design makes these drivers ideal for confined area use and a progressive torsion zone actively flexes to dissipate peak impact forces preventing fastener recess damage and tip breakage.
