View The Website

The Porter-Cable brand of power tools has a long established reputation for producing high quality, fully featured power tools. Their 390K belt sander lives up to that reputation as it has won industry awards for best tool. It has a powerful 3.5 amp EnduraTech motor with a variable speed of from 7,000 to 12,000 rpm so that it can give the optimum removal rate for tough jobs such as aggressive sanding, smoothing rough surfaces, through to fine finishing of wood. The electronic load-control monitors the rpm and ensures a constant operating speed for smooth sanding and is claimed to give over 40 percent faster material removal.

The Porter-Cable 390K has a palm grip with a low-profile. This gives it better control and therefore finish, as well as being more comfortable to hold. The rubber grip also has an ergonomic design making it more comfortable to hold even during those longer jobs.

To help make the work area cleaner and healthier the Porter-Cable 309K features an integrated dust port which can accommodate both one and one and a half inch vacuum hoses for more efficient dust collection.

Porter-cable have given the electric motor a couple of features which even the best sanders lack. These are an electronic motor brake, to reduce the time waiting for the machine to stop spinning waiting from 10 seconds to approximately 3 seconds. In addition, a separate mechanical brake acting on the pad reduces free-spin – thus just about eliminating gouging of the surface of the material being sanded.

The Reviews

The reviews for the Porter-Cable 390K were very positive with most users saying that the removal of material was quick and smooth. Most people thought that the vibration levels were very low for an orbital sander and that this model compared favourably with the best sanders in this respect. The dust collection system was another feature that reviewers commented favourably on, saying that its efficiency allowed them to work for longer without stopping to clean up the dust. Some of the users who left reviews were using this sander in a professional capacity, and they were of the opinion that for ease of use and quality of finish, this was one of the best sanders they had used.

Some reviewers mentioned that because this is a palm grip sander and it is a little larger than normal, users with small hands might find it tiring to use the sander for long periods. A couple of users also found that the port for the dust extraction system clogged up easily on their machines. This may be an isolated problem as most reviews mentioned that the dust collection system worked well.

Overall our conclusion is that the Porter-Cable 390K is one of the best sanders for the money. It has a comprehensive specification and satisfies professional users who need to produce high quality results. We have no hesitation in recommending this sander.
