Porter cable 7424 VS 7424xp | Features and Characteristics Comparison

Porter cable 7424 VS 7424xp

The Porter Cable 7424 and 7424xp are two random orbital sanders with some common features, as their model numbers suggest. This can make it very difficult to know which one to pick. A detailed review of features will help you decide which meets your requirements. Porter Cable is a leading brand with high-quality and professional-grade orbital polishers. In this post, we will review both products, explaining the pros and cons so that you will choose the one that works for you. 

Overview of the Porter Cable 7424

The Porter Cable 7424 is ideal for polishing and sanding automotive and marine projects. The 6-inch variable-speed random orbit polisher features a 4.5-amp motor for high overload protection and random orbit. 

It is a compact and lightweight polisher at 5-1/2 lbs. It delivers professional, swirl-free polishing action with an electronic variable-speed dial from 2,500 to 6,800 OPM. It accepts 5/16 to 24 spindle thread accessories, and its ball-and-roller bearing construction provides durability under industrial workloads. It features a proprietary counterbalance with a 6-in. sanding/polishing pad and a two-position removable side handle for greater comfort and control.

As the motor runs, there is little heat generated from it. Vibrations are also minimal. There is more heat and vibrations at higher motor speeds, but it is nothing uncomfortable to deal with while using the polisher. At high speeds, the noise level the motor puts out is high. The noise is almost loud enough to require hearing protection if you do not want to leave a ringing sensation in your ears afterwards.

The size of the machine polisher is small, but that does not compromise its performance. Using it for long periods remains comfortable. There is a large surface area to grab onto, making it easier to find a good grip to avoid hand fatigue. A lack of a handle makes it awkward to manoeuvre and control the polisher in tight spots. The speed knob is also close to one of the supporting hands and is easy to bump when manipulating the polisher, increasing the speed accidentally.

Pros

  • Compact and lightweight 
  • Durable
  • Minimal vibrations
  • Comfortable 
  • Good grip

Cons

  • Handling could be better
  • Can be noisy

Overview of the Porter cable 7424xp 

The Porter Cable 7424xp is a random-orbit machine powered by 4.5Amp. The speed varies from 2,500 to 6,800 OMP and accommodates 5/16-24 spindle thread accessories. It comes with two removable handles that make handling the tool easy. The roller bearing construction makes the machine durable. The size and weight are perfect for the position you will be working on. You can use both hands but with ease. 

If you do not use the screw on the handle, it will not compromise your production. The sander is comfortable to use and also fits small corners in a car. These include under the mirror, and it remains effective. The sander does not require a lot of maintenance. 

You do not have to lubricate it since it is lubricated by high-quality lube that lasts for life. However, you need to note that it is also an industrial tool that needs cleaning and checking parts once in a while. That is for safety and performance. 

There are a few drawbacks when it comes to the tool. When you are operating at low speeds, it becomes difficult to control the polishing tool. It tends to slow down a bit. The pad comes with cheap foam that does not last long. However, polishing pads are easy to buy at an affordable price. You may even get them with some accessories. 

Pros

  • Speed variance
  • Handy
  • Comfortable
  • Compact size
  • Zero maintenance

Cons

  • It is tricky to control at low speeds
  • Cheap foam pad
