40V BRUSHLESS Oil Pulse Tool

  • Precision & repeatable bolting – The 1/2″ square drive with 40–90 Nm torque range and hydraulic oil-pulse mechanism makes the RZ4014-WR90 ideal for consistent, accurate tightening of bolts—great for assembly lines or structural fabrication where joint integrity matters.
  • Medium- to heavy-duty component assembly – Its torque capability suits medium-size fasteners (e.g. M10–M12 range) — useful for mechanical assemblies, equipment build-outs, or structural assemblies where controlled torque is needed but with a stronger drive than small-screwdrivers provide.
  • Quality-controlled / traceable fastening work – Built-in auto shut-off when target torque is reached, plus LED + buzzer joint-status indication, enable consistent, documented fastening — helpful in settings requiring audit-ready tightening or repeatable torque results.
  • Lower fatigue, smoother operation over many cycles – The oil-pulse design reduces torque reaction, vibration and noise compared with conventional impact tools — making it more comfortable and less fatiguing for high-volume or continuous fastening tasks.

Tool Features

Technologies

Our patent-pending All-In-One motor includes the power, control & communication board along with the automatic winding stator with an interior permanent magnet design rotor, all enclosed in a die-cast cover. These one-unit components have several advantages, including weight reduction, longer lifespan, and crucially our number one design goal of efficiency as there are no additional components to cool.

We have leveraged decades of electrical expertise from some of the world’s leading electrical engineers to develop our wireless platform to record and control our professional assembly tools, that can be remotely controlled via our software or different protocols for PLC systems.

DC motors have traditionally been driven by carbon brushes to power the motor. Over time these wear out and need replacing. All our motors are brushless meaning that the motor is controlled electronically without the need for carbon brushes ensuring your tool is maintenance-free.

TECHNICAL SPECIFICATIONS

Key features include:

* The oil pulse unit uses oil hydraulics to effectively reduce torque reaction, vibration, and noise

* Precise auto shut-off when it reaches the desired torque with LED and buzzer indicator of joint status for either good or not-good fixing

* Patented Electronic Torque Control (ETC) for precise torque cut-off

* Features a display showing torque stage and error messages

* The brushless motor ensures the use of wear-free components, which reduces maintenance costs and extends the life cycle of the product
