Gas-Powered Rolling Core Drills

KOR-IT gas-powered rolling core drills combine portable drilling power with a stable, maneuverable frame. These machines are designed for professional concrete-coring applications where crews need more capacity and stability than a handheld drill without moving a trailer-mounted system onto the jobsite.

The lineup includes models with bit capacities from 8 to 16 inches, electric-start options, an auger-equipped configuration and a self-contained rolling model with its own onboard water system.

Choosing the Right Rolling Core Drill

Choose a model based on the required hole diameter and the type of drilling work being performed.

The EK-401-G8 is a practical choice for standard coring up to 8 inches. The EK-401-G17E offers the same drilling capacity with additional engine power and electric start. For holes up to 16 inches, consider the EK-416-G17E. The EK-616-G17E adds auger capability, while the EK-1750 provides an onboard water system and four rolling legs for easier jobsite movement.

Common Applications

KOR-IT gas-powered rolling core drills are suited for:

• Concrete floor and pavement coring
• Utility and plumbing penetrations
• Road and infrastructure work
• Large-diameter concrete openings
• Outdoor or remote jobsites
• Applications requiring auger capability

Portable Power and Stable Operation

The rolling frame helps crews move the drill around the jobsite while providing a stable platform during operation. Gasoline-powered motors reduce dependence on external electrical power, making these machines well suited for outdoor and field applications.
