JD-M5 15KW High-Frequency Core Drilling Machine

Product Overview

CAHARD JD-M5 is a 15KW high-frequency core drilling machine for concrete and reinforced concrete drilling applications. It supports standard core bit diameters from 150 to 420 mm and can be configured for extended drilling diameters up to 500 mm.

The machine offers a maximum drilling length of 1160 mm and supports forward and reverse rotation with stepless speed control across a 0–960 rpm range. It also features wireless remote control, a water-cooled main motor and a fan-cooled controller box. Available output-shaft specifications include M22, 1-1/4" and M32, with other options available subject to confirmation.

High-Frequency Core Drilling Machine Applications

Concrete & Reinforced Concrete Core Drilling

Suitable for core drilling in concrete and reinforced concrete structures.

Wall & Floor Penetrations

Suitable for circular penetrations through concrete walls and floors.

Pipe, Utility & MEP Openings

Suitable for drilling concrete openings for pipes, utilities and MEP installations.

Large-Diameter Concrete Drilling

Suitable for large-diameter concrete core drilling within the machine's supported drilling range.

Deep-Hole Concrete Drilling

Suitable for concrete drilling applications requiring greater drilling depth, with a listed maximum drilling length of 1160 mm.

JD-M5 Technical Specifications

Power Supply Note: Please confirm the required 220 V or 380 V configuration, 50 Hz or 60 Hz frequency and available site power supply before ordering.

Cooling Water Note: The catalog lists a motor cooling-water reference of 10°C and 5 L/min. Please confirm the required cooling-water conditions for the intended operating environment before ordering.

Drilling Configuration Note: The standard core bit diameter range is 150–420 mm. The drilling diameter can be extended up to 500 mm using the listed stackable configuration. Final drilling diameter, drilling depth and core-bit connection should be confirmed according to the project requirements.

Bracket Configuration Note: The standard bracket length is 1000 mm. Other bracket configurations are optional and may be priced separately. Please provide the required drilling depth and site setup if a different bracket configuration is needed.

JD-M5 High-Frequency Core Drilling Machine Features

150–420 mm Standard Core Bit Diameter

The JD-M5 supports standard core bit diameters from 150 to 420 mm for concrete and reinforced concrete drilling applications.

Up to 500 mm Extended Drilling Diameter

The drilling diameter can be extended up to 500 mm using the listed stackable configuration.

1160 mm Maximum Drilling Length

The listed maximum drilling length is 1160 mm. The final drilling setup should be confirmed according to the required drilling depth and core-bit configuration.

0–960 rpm Stepless Speed Control

The machine supports forward and reverse rotation with stepless speed adjustment across the listed 0–960 rpm range.

Wireless Remote Control

The machine supports wireless remote control.

M22 / 1-1/4" / M32 Output Shaft Options

The JD-M5 is available with M22, 1-1/4" and M32 output-shaft specifications. Other shaft options should be confirmed before ordering.

Water-Cooled Main Motor

The main motor uses water cooling during drilling.

Fan-Cooled Controller Box

The controller box uses fan cooling.

220 V / 380 V and 50 / 60 Hz Configuration

The JD-M5 is listed for 220 V or 380 V configurations and 50 Hz or 60 Hz operation. The required electrical configuration should be confirmed before ordering.

When to Choose the JD-M5

Choose the JD-M5 when its 15KW power class, 150–420 mm standard drilling range and up-to-500 mm extended drilling diameter meet the project requirements.

Consider the JD-M9 when higher rated power or an extended drilling diameter beyond 500 mm is required. Both models share the same listed 150–420 mm standard core bit range and 1160 mm maximum drilling length, while the JD-M9 provides 26KW rated power and supports extended drilling diameters up to 650 mm.

Final selection should take into account the required hole diameter, drilling depth, reinforcement condition, drilling orientation, expected workload, available power supply, core-bit connection and cooling-water conditions.

Tell Us About Your Core Drilling Project

To help CAHARD determine whether the JD-M5 is suitable for your project, please provide the following information when possible:

• Material to be drilled
• Reinforcement condition
• Required hole diameter
• Required drilling depth
• Number of holes or expected workload
• Drilling orientation: vertical, horizontal or other
• Required core-bit connection / output shaft
• Available 220 V or 380 V power supply
• Required frequency: 50 Hz or 60 Hz
• Available cooling-water supply
• Whether diamond core drill bits are also required
• Required quantity
• Destination country / port

If diamond core drill bits are also required, please provide the drilling diameter, drilling depth and material so CAHARD can recommend a suitable core-bit configuration.

CAHARD can help determine whether the JD-M5 15KW high-frequency core drilling machine is suitable for your required drilling diameter, drilling depth, core-bit connection, power configuration and project conditions.
