Pneumatic impact wrenches M7
Do you frequently need to loosen or tighten screws or nuts? Do you work with rusted or hard-to-disassemble threaded joints? Reach for one of the impact pneumatic wrenches from Mighty Seven (M7).
Which wrenches are available
The e-shop www.kompresory-vzduchotechnika.cz offers a wide range of impact pneumatic wrenches.
There are wrenches available for small bolts with a 3/8" square drive, suitable for bolts of size 13 mm, up to "heavy-duty" models that can handle bolts of size 50 mm and generate torque of up to 4,065 N.m.

How to choose a pneumatic impact wrench M7
Find the wrench type in the table below according to these criteria:
- Bolt size
- Wrench reach
Bolt size
How large a nut or bolt the wrench can move depends on the size of the clamping square drive: 1/8", 1/2", 1", or 1.5".
| A so-called socket is mounted on the square drive, which is a reduction part that has a square drive on one side for fitting into the wrench and a hexagon on the opposite side. Before buying a pneumatic wrench, go through the Sockets for Wrenches section and find out which sockets are available for the selected wrench. | ![]() |
You can also choose a wrench set with clamping sockets:

Wrench reach
If you need to reach a more distant bolted joint with the impact wrench, choose an impact wrench with an extended shaft (ending in a 5 in the type designation: NC4215, NC6215). You can extend the reach of the impact wrench with an extension bar.

M7 ratchet wrenches
For working with smaller bolted joints (up to 16 mm), pneumatic ratchet wrenches are advantageous. These very light tools are well suited for use in car service centers, for maintenance of cars or motorcycles. They have lower torque than impact wrenches, but a long service life, because their gearbox and ball bearings are made of hardened materials.

Which M7 ratchet wrenches are available

Socket attachment
Ratchet wrenches are terminated with a square drive, onto which a so-called socket or attachment is mounted, which is a reduction part terminated with a hexagon of the same size as the bolt or nut to be tightened or loosened.

On the portal www.kompresory-vzduchotechnika.cz you can find a range of sockets for wrenches.
Pneumatic grinders M7
Compressed air supplyFor pneumatic grinders to operate reliably and without faults, a supply of properly treated air is required. The supply air should be dry and clean, i.e. free of water and impurities, and lubricated as needed. Constant inlet pressure is important: 6.3 bar +10%, so the compressor should have 7 bar and it depends on the number of pneumatic tools connected. |

Safety when working with a grinder
Working with pneumatic grinders can easily lead to injury, so please read the instructions for working with grinders provided on the portal www.kompresory-vzduchotechnika.cz.
Grinders are relatively noisy devices, so protect your hearing. Loose parts of clothing, hair, straps, etc. can easily get wound around fast-rotating discs or grinding bodies. Adjust your clothing accordingly so that this cannot happen.
Protect your face and hands from burns and cuts. The face can be protected with a face shield.

How to choose an angle grinder?
The most important parameter is the disc size. As you can see in the table, each grinder type is designed for one disc size; do not fit a disc of a different size into the grinder, because each grinder size is designed for different rotational speeds. At unsuitable speeds, the disc may crack and injure the operator.

M7 pneumatic eccentric and vibration sanders
|
For sanding large wooden and metal surfaces, an eccentric sander will serve well. The disc is mounted eccentrically (with an eccentricity of 5 mm at the circumference). Thanks to this, you will not reach the same spot twice at the same moment with the sander. This way you avoid scratches, and the sanded surface will be smooth.
