OX 1 1/4" UNC Hollow Extension

Extend your wet core drill reach into deep or restricted walls without changing your setup.

The OX 1 1/4" UNC Hollow Extension is a tough, durable core drill bit extension designed specifically for wet core drilling applications. The 1 1/4" UNC fitting connects directly to UNC core bits, extending your drilling depth into thick walls, deep penetrations, and restricted access areas where the core bit alone can't reach the required depth.

Constructed from high-grade steel for robustness under the constant torque and vibration of core drilling, this extension keeps water flowing through the hollow centre to the cutting face for effective cooling and core removal during wet drilling. Available in 200mm and 300mm.
