3888/4/1 K SB Rapidaptor Universal Bit Holder stainless 1/4" x 50 mm - Wera 05073616001

When stainless steel screws are fastened with tools made of conventional steel, particles from the tool adhere to the surface and rust. This extraneous rust impairs the appearance and can even cause structural damage that results in expensive repair work. The 3888/4/1 K Rapidaptor universal holder is made of stainless steel and prevents these particles, while offering the full Rapidaptor function for bits with 1/4" hexagon drive.

Benefits

• Stainless steel design: no extraneous rust when fastening stainless steel
• Rapid-in and self-lock: push the bit in without moving the sleeve, the lock activates automatically on the screw and the bit is held wobble-free
• Rapid-out: push the sleeve forward and the spring mechanism lifts the bit off the magnet, even the smallest bits come out without extra 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
• Free-turning sleeve (Rapid-spin) for guiding the power tool and preventing slipping
