MASTER 35

The new Master 35® impact wrench has the same reliable, high-quality impact mechanism and gearbox that has been in use for the past thirty years, now powered by a more powerful engine that complies with EUR5 and EPA3 low emission standards.

Due to its increased power and high engineering specifications, it will remove/install most bolts and nuts in less than three seconds, and drill holes in wooden sleepers using one of our quick-release drill chucks.

It is easily carried by one person, simple to operate, has good balance, is easy to repair, and because it is so fast, it reduces damage from vibration exposure, especially when mounted on our tool carrier.

Advantages

Lighter weight
Increased power
Low vibrations
Faster operation
Lower maintenance costs
Improved efficiency

Technical data

Weight		17.9 kg
Engine		Two-stroke special Airtec EMAK 63.4 c.c. compliant with EUR5 and EPA3 standards
Power		3.4 HP 2.6kW @ 7800 rpm
Fastener Type		Bolt (16 – 32 mm diameter)
		Square (all sizes)
		Hexagon (up to 83 mm)
Noise Level		Operating levels based on ISO3744

Square Drive		Standard 1"
Torque Range		500 – 2,500 Nm approx. Higher torques can be generated under special conditions. The Master will loosen any screw fastener previously tightened by any other gasoline-powered impact wrench.
Vibration Exposure		Vibration exposure is more important than vibration, e.g., a low-vibration machine that takes a long time to perform a task creates greater vibration exposure than a higher-vibration machine that performs the task much faster.
