Top Grex Pin Nailer Review

What is a grex pin nailer?

A grex pin nailer is a machine tool that uses compressed air to allow the user to place many nails or staples on wood, metal, plastic, or any other material quickly and conveniently and in a short time. It is shaped like a gun and is associated with a compressor responsible for introducing pressurized air into its operating system.

How to choose a grex pin nailer and what to consider before purchasing one?

From this comparison of it, it appears that these are the most important aspects for users when choosing between one model or another:

1. Magazine Capacity: The best have a magazine capacity for up to 100 nails.
2. Versatility: It is recommended that the universal stapler magazine accepts flat head and loosehead nails and staples.
3. Gauge: At a minimum, the nailer should use nails up to 5 cm in length and staples between 3.2 and 4 cm. Depending on the model, you can use pins with a thickness of 0.6 mm, 0.8 mm, 1.2 mm, 1.4 mm, or 1.8 mm.
4. Compressor: at least 50 liters.
5. Pressure: the higher it is, the better we can work on hard materials. Ideally, it should offer between 4 and 8 bars of pressure.
6. Vibration: a low vibration level will allow us to work more precisely and comfortably.
7. Weight: the lower, the better. It is recommended that it be less than 1 kg.
8. Nailing depth: it will be greater or less depending on the pressure offered. According to the opinions on pneumatic nailers analyzed, it must allow the nail to be embedded, at least 10 cm deep.
9. Safety: For mounting cabinets, upholstery, crafts, or any other use, must have a trigger lock system, safety switch, and quick disconnect mechanism for compressed air.
10.  Electronic power regulation: in this way, we can adapt the tool’s performance to the type of material used.

How does a grex pin nailer work, and what is the use of it?

It consists of the following parts:

1. Compressor: it is responsible for introducing pressurized air into the mechanism. If it is cordless, then replaced by a compressed air cartridge.
2. Nail or Staple Cartridge– Contains 50, 100, or more nails or staples ready to be placed on the material.
3. Nail Drive Mechanism: This is a percussion gear that, using compressed air from the cartridge or compressor, launches the nail or staple at high speed into the material.
4. Non-slip grip: designed to hold the tool firmly.
5. Trigger: to fire each nail or staple individually.

When the grex pin nailer gun is started, the nail or staple exits the cartridge and goes into the drive mechanism next to the exit hole. The compressed air is then trapped in an air chamber, waiting for the user to press the trigger. In doing so, it is released by moving a piston that, using a percussive movement, ejects the nail or staple at high speed and with great force so that it passes through the work material.

What types of grex pin nailers are there?

We can differentiate different types of nailers based on the source of energy they use:

1. Pneumatic nailers: are those that use compressed air to release the nail or staple. They are the most versatile since they can be used for small DIY tasks and professional jobs, depending on the type of nails used.
2. Corded electric nailers: they are the simplest. They use an electric motor powered by a cable connected to the electrical network that generates an explosive force of combustion or compressed air to propel the nail. They can be spring-loaded or electromagnetic. They are ultralight, inexpensive, and quiet, although they do not offer as much power as pneumatic.
3. Battery Nailers– Same as electric nailers, but use a battery as the power source instead of a wire.
4. Gas nailers: similar to pneumatic nailers but, instead of having a firing pin moved by compressed air, they have a combustion chamber. They require a cable or a battery that generates a spark that causes said combustion. As it occurs, the pressure rises, and the nail shoots out. They are also recommended, heavy-duty nailers.
5. Gunpowder nailers: almost in disuse. They work in a similar way to gas but using gunpowder, which makes them especially dangerous.

Typical uses of grex pin nailer

The best pneumatic nailers give us the ability to do all of these tasks:

1. Construction: assembly and connection of plasterboard pieces, sheet metal, prefabricated structures, and even concrete.
2. Upholstery: upholstery of sofas or other elements with leather, leather, fabric.
3. Assembly: of metal and wooden structures.
4. Roofing: laying of plaster ceilings, asphalt fabric, etc.
5. Crafts: for crafts of all kinds.
6. Carpentry: the assembly of wooden boxes, drawers, structures, and furniture in general.
7. Finishes: on doors, cabinets, and wooden furniture in general.
8. Decoration: installation of pictures, curtains, lattices, lamps, and door and window frames.
9. Repairs: repairs to chairs, tables, and furniture in general that have suffered any damage.
10.  DIY: fixing furniture to the wall, making artisan furniture, crafts …

What types of nails does a grex pin nailer need?

We can perform the tasks after buying a grex pin nailer will be determined by the type of nails we use. The following are available:

1. Polished steel nails: they have a flat or lost head and are the most used. They are handy for placing skirting boards, frames, and moldings and for assembling pieces of wood.
2. Zinc-plated steel nails: they can be flat head and threaded body (resistant to extraction, easy to nail and suitable for long-term and challenging work); glazier (specific for glasswork); and crampillion (they have a circular head and a ‘U’ shape and are perfect for roofs and brick walls).
3. Galvanized steel nails: they have a broad head and, thanks to the galvanization that prevents oxidation, they are perfect for plaster.
4. Wrought iron and brass nails: used to make decorative finishes on wood. They have a round or pyramidal head.
5. Polished bronze nails: specific for upholstery.

Generally, a professional or industrial grex pin nailer can handle nails between 1.5 and 8 cm long. However, what we need to look at when choosing is the width of these:

1. 0.6mmnails: headless nails (pins) and mini brads (small-headed nails). Only for wood, moldings, and door frames as they can be easily hidden with paint or varnish.
2. 0.8mm nails: pins and mini brads slightly thicker than the previous ones and specific for furniture, drawers, and extensive moldings.
3. 1.2 mm nails: the most used. These are brads (standard size headed nails) that provide excellent hold. Being challenging to hide, they are usually placed on plasterboard and in the invisible part of wooden or metal structures.
4. Nails between 1.4 and 1.8 mm: specific for heavy work on rigid materials such as cement, brick, or concrete.

It does not matter if we have bought a cheap grex pin nailer or one of the best on the market. When using it, we must follow the following safety recommendations:

1. Safety equipment:> 87+ certified goggles, hard hat, noise-inhibiting ear cups, and steel-toed boots.
2. Read the manufacturer’s instructions carefully always have the manual available in the work area.
3. Check all the componentsof the tool before starting work.
4. Inspect work material for items that may cause nail kickback.
5. Keep your hands at least 30 cm away from the nailing area.
6. Use the nailer, keeping it away from the body.
7. Do not use the nailer when other people are around.
8. Disconnect the compressor or compressed air cartridgewhen trying to remove jammed nails, going up or downstairs, stopping using the nailer, or passing it to another person.

Why Do Air Nailer Accidents Happen?

Even heavy-duty, heavy-duty pneumatic nailers are not dangerous tools as long as they are used correctly. Here we explain why most accidents in which they are involved occur:

1.  occurs when the nail is shot on a rigid surface that it cannot pass through. It causes it to be bounced towards the operator or thrown like a projectile. To avoid it, necessary to check the work surface for metallic elements.
2. Calculation errors: the most common are not maintaining contact between the tip of the nail and the material and placing the hands in the nail path. Please take a second to analyze our position before shooting.
3. Poor Posture– Nailer should never be used above shoulder height. We must also take extreme precautions when operating on ladders, in confined spaces, or when we have to hold it with our non-dominant hand. We must also keep the body as far away as possible from the tool.
