What is the M7 NC-4235H best used for?

The NC-4235H is a 1/2″ drive air impact wrench built for removing and installing bolts and nuts in vehicle maintenance and equipment assembly. With a maximum torque of 1,100 ft-lb (1,491 Nm) in reverse, it handles stubborn lug nuts and corroded fasteners in daily shop work.

Who is this impact wrench designed for?

It is designed for professional users in tire shops, auto repair, general workshops and fleet service — the entry point for shops that want tool-free hammer-case maintenance in a standard 1/2″ impact wrench.

How is it different from a standard 1/2″ air impact wrench?

A patented grease hole allows fast, tool-free lubrication of the impact mechanism, wrapped in a durable composite housing at a compact 180 mm, 2.1 kg body. A twin-hammer mechanism delivers consistent power with less vibration.

What is the patented grease hole (EZ Grease) for?

It lets a technician grease the hammer mechanism directly through the housing, without disassembling the tool — helping restore torque output and keep the tool in service, reducing repair costs and shop downtime.

What does the 200–600 ft-lb torque range mean?

That is the working torque range (271–678 Nm) for tightening in forward operation. For loosening, the tool delivers up to 1,100 ft-lb (1,491 Nm) of maximum torque in reverse.

What are the dial reverse and 360° air inlet for?

The rotary-knob directional switch lets you change rotation direction with one hand, without repositioning your grip. The 360° swivel air inlet keeps the hose from twisting, so the tool stays maneuverable at any work angle.

Is it suitable for auto repair, tire and maintenance work?

Yes. It runs on standard shop air (90 PSI / 6.3 bar) and handles bolts up to 3/4″ (19 mm) and nuts up to 30 mm. The 180 mm length and 2.1 kg weight suit repeated use in tire, auto repair and maintenance bays.
