Trying to use a cheap flap disc made of low-grade materials and advanced methods undergoors basic enhancement techniques will more than often prove useless. It can be beneficial for casual or light usage, but in comparison to dryer and more expensive options, it simply does not perform anywhere near the same level. With a cheap option, for instance, the aluminum oxide roughness will not only be subpar but the machining will also result in tighter binding which is unproductive as it tends to use more energy for the activity. Enthusiast or not, this isn't the best option for more complex work. Let's say that a homeowner has to perform some trivial refinishing or polishing on some wooden and metal surfaces; a cheap flap disc can suffice for non-serious DIY enthusiasts without making him worry aboutperformance metrics and the like, but for someone who has a professional mindset and comes with heavier workloads, this will not be the ideal choice.
