Who Is This Hand Held Core Drill Designed For

The EK803 Hand Held Core Drill is specifically designed to cater to the needs of professionals in different fields. General contractors, plumbers, pool fence installers, and electrical contractors benefit from its compact and lightweight construction. The ergonomic design allows for comfortable handling and maneuverability, making it suitable for various applications.

Materials and Use Cases

The EK803 hand held core drill is engineered to excel in a variety of drilling scenarios. It is specifically designed for core drilling in walls, floors, roofs, concrete patios, and even road surfaces. This versatile core drill is a reliable choice for drilling into materials such as asphalt, concrete, reinforced concrete, masonry, brick, and other typical construction materials. With its exceptional performance and durability, the EK803-110 can tackle various use cases with ease.

Three Speed Hand Held Core Drill

The EK803 hand held core drill features three selectable speeds, allowing for efficient drilling of core drill bits up to 3 inches in diameter when used as a handheld tool. When mounted onto the optional EK803 Stand (sold separately), this drill can accommodate larger core drill bits of up to 6 inches in diameter. The three-speed settings of the EK803 hand held core drill are optimized for different drilling requirements, ensuring precise and effective results.

Rotational Speeds and Optimal Uses

The EK803 hand held core drill offers three rotational speeds to cater to various drilling needs. Each speed setting is optimal for specific core drill bit diameters and materials:

Top Gear (3450 RPM): This speed is ideal for smaller core drill bits ranging from 0.5 to 1.5 inches in diameter. It provides the necessary rotational power for efficient drilling in materials such as brick and lightweight concrete.

Middle Gear (1800 RPM): The middle gear speed is suitable for core drill bits with diameters ranging from 1.5 to 2.5 inches. It offers a balanced combination of power and control, making it perfect for drilling in reinforced concrete and masonry.

Bottom Gear (950 RPM): The bottom gear speed is specifically designed for larger core drill bits, ranging from 2.5 to 4 inches in diameter. It delivers optimal torque and stability, ensuring effective drilling in heavy-duty materials like thick concrete slabs and road surfaces.

Industry Standard Threads on The Spindle

The EK803 hand held core drill comes equipped with an industry-standard thread of 1.250”-7 on the core drill spindle. This adapter allows the drill to fit most standard core drill bits. However, when drilling with a diameter of less than 1.5 inches, you may need an adapter to downsize the 1.25"-7 thread to a 5/8"-11 thread count on the spindle. This adapter can be purchased separately to ensure compatibility with a wide range of core drill bits.

Wet Core Drilling or Dry

The EK803 hand held core drill offers versatility when it comes to drilling methods. It comes standard with a water connection, allowing for wet coring. Wet coring involves using water as a coolant during the drilling process, which helps reduce heat and dust, resulting in cleaner and more efficient drilling. However, depending on the material being drilled, specialty dry core drill bits are also available for situations where wet coring is not feasible or required.

Core Drill Power Source and Safety

The EK803 hand held core drill is designed to operate on a 110V power source, ensuring compatibility with standard electrical outlets. It is important to note that the core drill is equipped with a safety clutch, which provides an added layer of protection by disengaging the drill in the event of a sudden increase in torque or binding. Additionally, the core drill features electric leakage protection (PRCD), ensuring safety during operation.

Optional Core Drill Stand / Core Drill Rig

While the EK803 is primarily a hand-held core drill, it offers the option to be used with an optional core drill stand for added stability and convenience. The EK803 Stand comes with leveling bolts, providing a secure drilling platform when working with larger core drill bits of up to 6 inches in diameter. This optional accessory enhances precision and control, especially for drilling tasks that require higher accuracy and prolonged drilling periods.

Conclusion

The KOR-IT EK803 3-Speed Hand Held Electric Core Drill is a reliable and versatile tool designed for professionals in various industries. Its lightweight and portable design make it a preferred choice for general contractors, plumbers, pool fence installers, and electrical contractors. With its three-speed settings, compatibility with standard core drill bits, wet or dry coring options, and safety features, the EK803 offers efficiency, precision, and ease of use for a wide range of drilling applications.
