Coil S-SMK, 32mm x 4.5m 72455

Drain cleaning spiral – reliable blockage removal

The S-SMK spiral is a solid tool designed for effective cleaning of drains and unclogging sewer pipes with a diameter of up to 200 mm. It is ideal for both professional plumbers and demanding home users. Its construction provides stability and durability, even during difficult tasks such as removing roots or milling.

Construction and application

The 32 mm diameter and 4.5 meter long spiral is designed to work with drain cleaning machines. The tapered insertion cone on the T-groove facilitates the mounting of various working tools and extending the spiral, allowing it to be adapted to the specifics of a given problem. An additional plastic core protects the spiral from clogging, which translates to a longer life and trouble-free operation.

• Versatility: It will work in various sewage installations, both in residential and commercial buildings.
• Durability: Made of high-quality spring steel (standard C DIN 10270-1, material no. 1.1200) provides resistance to torsion and high loads.
• Ease of use: The tapered guide on the connector facilitates coupling the spiral to the machine, even with work gloves.
• Protection against dirt: The plastic core minimizes the risk of the spiral clogging with sediment and contaminants.
• Torque transfer: Tightly wound wire coils ensure efficient torque transfer during operation.

Technical parameters and characteristics

The S-SMK spiral stands out from the competition thanks to the use of a special material hardening process, which increases its flexibility and durability. A reliable connection system with a groove and a locking button made of NIROSTA stainless steel guarantees a stable connection to the machine and safety during operation. The increased wire diameter provides better torque transfer and greater stability when cutting roots or milling. The spiral has a diameter of 32 mm, a length of 4.5 meters, and a wire thickness of 6 mm. It is made of high-quality spring steel (1.1200) and weighs 7850 g. It has a connecting nut and a T-groove, and its working area diameter is 75-250 mm.
