QHC Holders for Single Point Tools

QHC Holders for Single Point Tools

Please allow 1-2 weeks delivery outside the USA

Our QHC Holders are engineered for high-pressure coolant delivery and maximum rigidity in single point tooling applications.

Made from heat-treated steel, each holder features four lock-down screws and precision-positioned coolant holes that direct flow right to the cutting edge—enhancing chip evacuation and tool life.

Available in both inch and metric versions, QHC Holders include two flats for stable alignment and offer optional adjustable backstops for fast, repeatable tool changes.

Ideal for qualified threading tools and boring bars.
