Power and Precision in the Palm of Your Hand: COR Series Hydraulic Core Drills

Upgrade your drilling game with the COR 5 and COR 15 Handheld Hydraulic Core Drills. Engineered for professionals who demand high performance without the bulk of traditional rigs, these drills offer the perfect blend of power-to-weight ratio and job-site versatility.

Unlike electric alternatives, our hydraulic series thrives in wet environments and high-torque scenarios, ensuring you never stall when the job gets tough.

Key Performance Features

• Spark-Free Operation: Ideal for sensitive environments or underwater applications where electricity is a hazard.

• Constant Torque: Hydraulic power provides consistent rotational force, preventing bit binding even in heavily reinforced concrete.

• Ergonomic Design: Built with vibration-dampening handles to reduce operator fatigue during extended use.

• Variable Speed Control: Fine-tune your RPM directly via the trigger for precise starts and clean finishes.

Model Comparison: COR 5 vs. COR 15

Choose the model that fits your specific project needs:

Feature	COR 5 (The Specialist)	COR 15 (The Workhorse)
Best For	Small diameter, high-speed precision	Large diameter, high-torque drilling
Drilling Range	Up to 100 mm (4 in)	Up to 300 mm (12 in)
Flow Rate	20 L/min	20–30 L/min
Weight	7.5 kg (Lightweight)	9.2 kg (Heavy Duty)
Typical Use	Anchor holes, plumbing, electrical	HVAC ducting, manholes, heavy masonry

Why Choose Hydraulic Over Electric?

1. Safety: Zero risk of electric shock in wet conditions or standing water.

2. Durability: Fewer moving internal parts mean less maintenance and a significantly longer lifespan.

3. Power: Delivers higher torque at lower speeds, allowing you to cut through rebar-heavy concrete with ease.

Note: Both models feature a standard 1-1/4″ UNC male thread (adapter compatible) and built-in water swivel for bit cooling and dust suppression.
