Professional maintenance/service equipment that cuts seized, thread-damaged, or corroded nuts in a single stroke with 700-bar-class hydraulic force — without damaging the bolt/stud and without sparking.
Cutting capacity depends on nut wrench size, nut grade (8/10/12), and height values. Let us help you determine the right model for your application using our selection guide.
No heat and no sparks; adjacent parts, gaskets, and coatings stay protected.
Far safer and faster than grinding or cutting discs.
Ergonomic body, compact design suited to tight spaces.
Replaceable blade; can be flipped to use the second face.
High-strength steel, single-piece or bridge design.
The jaw opening is fitted over the nut; the cutting blade is aligned with one face of the nut.
Pressure from the pump drives the cylinder, applying high cutting force to the nut through the blade.
The blade splits and weakens the nut; a single cut is enough for most models.
Pressure is released; the spring-return mechanism pulls the piston and blade back to the starting position.
The nut is removed with pliers; the bolt/stud can often be reused depending on condition.
Blade: heat-treated special tool steel · Body: high-strength steel · System: single-acting spring return
The HSP series covers the full 10–105 mm nut wrench-opening range (M6–M75 bolts) across 9 models, from the HSP1319 (10–19 mm) up to the HSP90105 (90–105 mm). You can determine the right model based on nut size, grade (8/10/12), and access conditions using our selection guide, or send us your details through the quote form.
All HSP models run on a hydraulic pump with a 3/8″ NPT/F connection rated to a maximum operating pressure of 700 bar (12,000 psi). Cutting force ranges from 49 kN (HSP1319) up to 1320 kN (HSP90105), depending on the model.
The blade is manufactured from heat-treated special tool steel and cuts nuts with a hardness up to HRC 44. The blade is a replaceable, double-sided design — once one face wears, it can be flipped to use the second face, reducing operating costs.
Grinding and cutting discs generate heat, sparks, and metal swarf, whereas a hydraulic nut splitter performs the split in a single stroke with no heat and no sparks. This protects adjacent parts, gaskets, and coatings, and lets a single operator complete the job faster.
No — the HSP series operates on a purely mechanical splitting principle and produces no sparks. This makes it safe to use in sensitive environments such as petrochemical and energy facilities, shipbuilding/shipyards, mining, cement plants, and defense/infrastructure applications where spark risk is unacceptable.
Yes. We handle maintenance and repair for HSP series nut splitters in-house — send us your unit and we'll inspect it and manage the repair process. We also manufacture original spare parts (including cutting blades) on request for the models we produce; we don't maintain a separate parts catalog, but you can contact us directly for the part you need.
