Ko-Ken 3112N and 4112N attack driver, 3/8" Drive x 159mm

Ko-Ken 3112N and 4112N are attack drivers with square drives of 3/8" and 1/2". Lengths are 159 and 163mm.

Where this product is used

• Loosening and tightening fasteners by striking the driver with a hammer, which converts the blow into a twisting force
• Maintenance and repair work where a fastener is tight and a normal handle will not move it
• Driving sockets and bit holders that fit the square drive

Features

• Square drive: 3/8" and 1/2"
• Black finished head, manganese phosphate treated so the chrome does not peel off when the head is struck
• Body shape gives a stronger grip and converts striking power into twisting power
• Special heat treatment against cracking: the striking head is slightly softer and the cam part is harder
• A strong spring converts striking power efficiently into twisting power
