The Festool Rotex 150 vs Bosch Professional GEX 150 compares sanding tools from different manufacturers. They certainly have more differences that will make you choose one over the other. They have the same dust collection system, the same brake pads and random orbital sanders. They have a dual action, sanding and polishing at the same time. They differ in speed, weight and cost. Which you prefer will lead you to your first choice. But you may change your mind after you take a closer look at the two products below.

Key Features of the Festool Rotex 150

Safety features

It has a brake pad that avoids set-down and start-up gouges. The auxiliary handle prevents your hand from fatigue and vibrations because the tool is aggressive. It has a soft start and stops the sanding machine from jerking your arm. 

Dust collection system

The sander comes with a Dust extraction port. It is easy to remove with a slight push of the green button. It keeps the machine away from dust. It has an enclosed gear system that does not allow dust particles to enter the gearing and bearing unit. That makes the sanding machine durable. Foreign objects have no access to the sanding device. The dust port is located at the bottom back of the sander. It increases the life of the pads.

Power and speed

The 6Amp motor has a speed rotary motion of 320 to 660 rotations per minute. The motor produces 3,300 to 6,800 orbits per minute. That means more power that is ideal for tough applications. As much as the machine is fast, it remains accurate. It makes fine applications. The speed variance allows you to maintain a constant speed on different loads.

Sanding pad

The sanding machine uses a sanding pad that is 6inches in diameter. The pad uses the hook and loop design. That makes it easy to remove and replace. The Fastfix pad allows the machine to operate without additional tools. It will enable you to change the sanding pads when the old one gets worn out. The sanding pad makes rotational and orbital patterns.

Overview of the Bosch Professional GEX 150

The Bosch Professional GEX 150 sander model has shown its strengths in performance, dust extraction, and ease of use. The model is lightweight and has an ergonomic design. The ergonomic design makes it easy to handle comfortably. You hardly have fatigue after a long day using the Bosch sander. That makes it ideal for heavy loads. The discs are easy to remove and replace. The pad dampening system does not leave swirl marks on the surface material. 

The micro-filter system keeps your environment clean and protects you from dust-related diseases. It uses a soft sanding pad that gives fine sanding, coarse sanding, and polishing. It also works on curved materials. The microfilter dust canister used by the Bosch sander keeps your work environment clean. You operate it using one hand. The variable speed controls allow you to change your speed depending on the material you are working on. 

The hook and loop attachment makes it easy to change the sanding pads. The sanding disc stays in place for high performance. The pad dampening system keeps your material free from swirls. The challenge with a Bosch sander is the engines that accompany some of its models that fail to pull heavy workloads. The body of the sander tends to heat up when in use. It weighs up to 5.84kg.

Key features of the Bosch Professional GEX 150

Pad dampening system

The 6-inch Bosch random orbit sander has a pad-dampening braking system that removes the swirl marks. That leaves the surface with a nice finish to the workpiece. The rapid removal feature gives the surface an ultra-smooth finish. 

Dust collection system

The Bosch Palm has a built-in micro-filter system that reduces the volume of dust produced. The micro-filter canister collects dust from the machine. It traps about 98 per cent of the particles that are half a micron smaller in diameter. The canister has a transparent material that allows you to measure the level of dust collected. That helps you avoid blockage. It does not matter how much you have used the canister. It remains transparent for as long as the sanding machine is still functioning. 

Hook and loop attachment

The hook and loop attachment makes changing sanding pads easy and quick. Align the holes of the sanding pad to the sanding disc and press firmly. A clicking sound assures you that you have done it correctly. 

Soft grip

The sander is easy to hold with comfort. Choose the soft-grip surface from the top, base, or front when operating the sanding machine. That is convenient, unlike standard sanders you only hold from the front. The power cord has an ergonomic design that prevents the tool from slipping off your hands. The soft grip keeps your hands safe from vibration. You can use the machine on heavy loads without hurting your hands or arms.
