3888/4/1 K Rapidaptor universal bit holder, stainless, 1/4" x 50 mm - Wera 05071100001

When stainless screws are driven with tools made of conventional steel, abraded particles can stick and rust. The Wera 3888/4/1 K is made of stainless steel and avoids this extraneous rust, while offering Rapidaptor technology for rapid bit change over a length of 50 mm.

Benefits

• Stainless design to prevent extraneous rust when fastening stainless steel
• Rapid-in and self-lock: push the bit in without operating the sleeve, it locks automatically when applied to the screw and sits wobble-free
• Rapid-out: slide the sleeve forward and the spring mechanism lifts the bit off the magnet, even the smallest bits without auxiliary tools
• Chuck-all: takes 1/4" bits as per DIN ISO 1173-C 6.3 and E 6.3 as well as Wera series 1 and 4
• Rapid-spin: free-rotating sleeve to guide the cordless screwdriver, also usable as a short extension in 1/4" applications

Applications
