KS TOOLS 1/4 inch Hex Bit Holder with Reversible Ratchet Head, 85mm, 72-Tooth, Chrome Vanadium, DIN 3126 / ISO 1173 331.0660

With a compact 85mm body and a 72-tooth reversible ratchet head, this KS TOOLS bit holder delivers a 5° working arc in confined spaces where a full-size ratchet won't fit. The 1/4" hex drive accepts standard insert bits and locks them securely via a ball retention mechanism, while the matt satin chrome finish over chrome vanadium steel resists corrosion and wear.

Overview

The KS TOOLS Werkzeughalter mit Umschalt-Ratschenkopf (331.0660) is a professional-grade bit holder with an integrated reversible ratchet head. It is engineered for driving 1/4" hex insert bits in tight or recessed locations, such as inside engine bays, under dashboards, or within machinery housings. The ratchet mechanism features 72 teeth, providing a 5° indexing angle for precise fastener engagement even when swing room is minimal. A simple lever switches between clockwise and counter-clockwise operation, allowing the user to tighten or loosen without removing the tool from the fastener.
