Carries the Load

The DH Series, rooted in Bay Shore Systems’ legendary LōDril design, is the workhorse excavator-mounted drilling system built for difficult access, reach, and long-term reliability. With telescoping kelly capability, low-clearance advantages, and proven torque performance, DH rigs are built to drill deep in places others can’t — and keep running for decades.

Built to Drill. Built to Last.

The Bay Shore DH Series delivers real drilling performance.

The Bay Shore DH Series delivers foundation drilling performance in the hardest-to-reach places. Built as an excavator-mounted system, DH rigs bring high rotary torque, deep drilling capability, and true versatility to jobsites where conventional equipment can’t operate. From slopes and uneven terrain to low-clearance work under bridges, power lines, or inside structures, the DH Series puts drilling power exactly where contractors need it. With telescoping kelly configurations, 360-degree reach, and torque ranging from 15,000 to 110,000 ft-lb, DH rigs are built to turn difficult access into profitable work—giving contractors the flexibility to take on more jobs without compromise.

Contractors choose DH Series Rigs because they turn excavators into purpose-built drilling machines—without sacrificing productivity.

Built Different.

Excavator-mounted drilling exposes weak designs fast. The DH Series is built to hold up in real production drilling.

Purpose-Built for Excavators

Designed from the ground up for excavator mounting—not adapted attachments.

Torque That Works Downhole

High, consistent rotary torque that holds through changing subsurface conditions.

Controlled Crowd and Rotation

Predictable drilling control improves hole quality and reduces tool wear.

Stable, Efficient Operation

Engineered to work with excavator geometry for balance and control.

Built for Production Jobsites

Heavy-duty construction built to withstand daily foundation drilling.

Smart Controls.

Real-Time Results.

Integrated control systems give operators clear feedback and responsive control to maintain consistent drilling performance. Designed for real jobsite conditions, these controls help reduce operator fatigue while improving accuracy and efficiency throughout the drilling cycle.

Seamless Operation

The EOH system unifies excavator and drill head functions so operators stay focused on drilling.

Touchscreen Adjustments

Tune torque, crowd force, and rotary speed on the fly to match changing ground conditions instantly.

Faster Fixes

Built-in diagnostics cut troubleshooting time from days to hours.

Operator Insight

Track run hours from the cab to support better maintenance planning and operator accountability.

Carrier Ready

Fully compatible with the latest EOH excavators—so you get the rig you want, on the machine you choose.
