X301 ZZ Turbo - Pre-Stressed Concrete Diamond Core Bit
The X301 ZZ Turbo is a premium concrete core drill bit designed for demanding work in pre-stressed concrete. Its segment configuration supports consistent cutting performance where standard core bits may encounter heavy reinforcement.
Close-spaced diamond segments maintain frequent contact with the work surface, helping the bit manage heavy rebar while maintaining a steady drilling action. This design is suited to professional concrete coring applications requiring durability and control.
Built for Reinforced Concrete
The bit features an 8 mm (.315 inch) segment height for extended usable wear and reliable material removal. The segment profile is engineered for demanding concrete conditions rather than general-purpose light-duty drilling.
Its 14-inch barrel length supports deeper core drilling operations and provides additional working reach for construction, restoration, and structural concrete work.

Reduced space between segments helps limit segment loss when the bit encounters reinforcement. This contributes to more consistent performance and helps keep the core drilling process controlled through variable concrete conditions.
The X301 ZZ Turbo is intended for professional concrete core drilling equipment and applications where bit construction, segment retention, and drilling depth are critical considerations.
Application
Use this Diamond Core Bit for pre-stressed concrete, reinforced concrete, and coring work involving substantial rebar. Select the appropriate bit diameter and compatible drilling system for the planned application.
For demanding concrete coring requirements, the X301 ZZ Turbo provides a purpose-built configuration focused on reinforcement handling and dependable service life.
