Extension Bar

EXTENDED CORING DEPTH

SHIBUYA Extension Bar

The SHIBUYA Extension Bar is designed to increase the drilling depth of diamond core bits for deep concrete coring applications. Installed between the core drill machine and the diamond core bit, the extension bar provides additional reach when standard core bit lengths are insufficient to complete the required drilling depth.

Manufactured from high-strength steel with precision-machined threads, the SHIBUYA Extension Bar ensures secure connections, excellent torque transmission, and reliable drilling performance. Its robust construction minimizes vibration and maintains drilling accuracy, even during demanding deep coring operations.

Available in various lengths including 100mm, 150mm, 200mm, and 350mm, the SHIBUYA Extension Bar is an essential accessory for contractors performing deep concrete drilling, wall penetrations, utility installations, and infrastructure projects.
