Product Description
Detailed Description
Product Overview
The GK114BL Electric Hole Cutting Machine is a high-efficiency, portable pipe tapping tool designed for fire protection, water supply, and industrial piping systems. It creates precise holes in steel, galvanized, and ductile iron pipes for mechanical tees, branch connections, and sprinkler heads. With a compact design and powerful 1800W motor, it is ideal for both on-site construction and workshop use.
Technical Specifications
Key Features
High Torque & Stable Cutting: 1800W motor with low-speed (120RPM) high-torque output ensures smooth cutting on thick-walled pipes without stalling or burning out.
Wide Application Range: Covers Φ16–Φ114mm holes, meeting common needs for sprinkler connections, mechanical tees, and branch outlets.
Lightweight & Portable: Only 20KG, easy to carry and operate by a single person in tight spaces or construction sites.
User-Friendly Operation: Simple chain clamping system and manual feed control, suitable for both professional plumbers and new operators.
Durable Construction: Built with high-quality materials for long service life, compatible with standard hole cutters and pilot drills.
Applications
Fire Protection Systems: Drilling holes for sprinkler heads and mechanical tees in main fire pipes.
Water Supply & Drainage: Adding branch connections, meters, or access ports in existing pipelines without shutdown.
Industrial Piping: Creating outlets for cooling water, compressed air, and process lines in factories.
Pipe Renovation & Repair: Retrofitting old pipelines with new branches, avoiding large-scale demolition.
Grooved Pipe Projects: Matched with roll grooving machines for complete grooved pipe installation workflows.
Step-by-Step Operation Guide
Preparation: Secure the machine to the pipe with the chain clamp, ensuring it is perpendicular to the pipe surface. Install the correct hole cutter and pilot drill for your required size.
Power Connection: Connect to a 220V power supply and verify the motor rotates clockwise (correct cutting direction).
Center Drilling: Start the motor and slowly turn the feed handle to lower the pilot drill, creating a clean center hole to prevent the cutter from wandering.
Cutting the Hole: Continue feeding the cutter slowly into the pipe. Do not apply excessive force to avoid damaging the cutter or overloading the motor.
Finishing & Cleaning: Once the hole is cut, reverse the feed handle to retract the cutter. Turn off the power, remove the machine, and deburr the hole edge for a smooth fit.
Installation: Attach the mechanical tee or branch fitting to the new hole, ensuring proper sealing and alignment.

Compatibility
Drop-in replacement
This Junyue grooved piping component is engineered for seamless compatibility with Victaulic Style 07 and Grinnell system layouts. Verify pipe OD, groove profile, gasket compound, pressure class, and project approvals before specifying as a replacement.
Technical FAQ
Application limits
- Can it be used for steam above 150 C?
- No. Do not use for steam above 150 C unless a written project-specific approval, rated gasket, and compatible body material are confirmed.
- Can it replace any grooved fitting without checking pipe OD?
- No. Pipe OD, groove standard, working pressure, gasket material, and certification scope must be matched.
- Is it suitable for potable water by default?
- No. Potable water use requires confirmation of coating, gasket compound, local sanitary approval, and project compliance.
- Can it be used in corrosive chemical service?
- Not by default. Chemical compatibility must be verified against the medium, concentration, temperature, and coating system.
