Sizing the SP-HD400 to the Job
The SP-HD400 is built for the calls that stall compact drums: 4 to 6 in. main lines in commercial buildings, apartment stacks, food-service grease lines and municipal laterals. A heavy-duty electric motor turning at 220 RPM keeps torque on the cable through roots, hardened grease and scale — the three blockages that stop lighter machines.
It is the right machine for:
- Plumbing contractors clearing main stacks and building drains on service calls
- Municipal and utility crews working storm and sanitary laterals
- Rental yards that need a unit strong enough for commercial customers
- Facility teams in hotels, hospitals, malls and factories
How the Cable Drum System Works
The cable feeds from a large-capacity 400 drum driven by the heavy-duty electric head. The operator advances the cable by hand while the motor provides rotation, using the forward / reverse control to work the cutter past a blockage and the emergency stop to shut the machine instantly if the cable binds. The 1/2 in. heat-treated spring-steel cable is stiff enough to carry torque down a long run without coiling, yet flexible enough to track the bends in the pipe.
Cutter Heads and Accessories
The SP-HD400 ships with a standard clearing head and accepts the full range of screw-on cutters:
- Drop-head auger — general clearing for soft blockages
- Grease cutter — opens up soft grease and sludge in kitchen lines
- Root cutter — shaves tree roots from the pipe wall in outdoor laterals
- Wheel kit and extra drums — optional for rental and high-volume fleets
Built and Tested in Chonburi, Thailand
Every SP-HD400 is assembled, wired and function-tested at THAIMAKE’s own factory in Phan Thong, Chonburi — a 6,000+ sqm facility where the drum, frame and cable assemblies are made in-house. Each unit is ETL Listed to UL 73 / CSA C22.2 No. 68 by Intertek before it ships, so it arrives import-ready for the North American market. Buying factory-direct means you can specify your own brand, color and packaging on the same production line.

For Contractors and Municipal Teams
The SP-HD400 pairs a larger motor and heavier cable with the 400 drum, so it powers through roots, grease, and scale in 4-6 in. municipal and commercial lines where lighter machines stall. The wheeled dolly moves it between van and job site without lifting. It is the machine rental companies buy when customers keep breaking the compact units.
Like every SP series model, it is ETL Listed for North America and tested before packing. OEM orders can specify your brand color, logo, and bundled accessory kits.
