Some people might say that a combination of a belt and disc sander is not a priority or necessity for someone who works in a woodworking shop, but the fact that you are getting two tools in one package is more than enough reason to invest in it.
If you are employed in the woodworking industry, you know for a fact that a disc sander is a valuable tool for producing precise edge work such as trueing outside curves as well as fitting mitre joints. Meanwhile, a belt sander is the one you will use when you need to flatten edges and faces, as well as in shaping contours and smoothening inside curves.
Keep in mind that most if not all combination belt and disc sanders available for purchase these days are not industrial-quality tools, but they are more than enough to take on home improvement jobs. The reason why they aren’t labelled as industrial-quality is that the manufacturers do not expect you to use them consistently.
One of the things you must look for in a sander is a port for dust collection. In other words, do not buy one without that port. It is best that you settle for something with large-diameter ports because it has the least tendencies to restrict airflow. Many of the models you will encounter when you go window shopping have separate ports for the belt and disc, which means they also need two hoses. You can also look for a variety with a single tube with a moving mechanism, although it might be inconvenient to use at first. While there are sanders with onboard dust collection, it is best that you go for one with a dedicated dust collector paired with a filter bag.
When it comes to using a belt and disc sander, there is no denying that the fingers are the most at risk of getting injured. Keep in mind that the disc and belt will simultaneously operate even if you only use one of them. Therefore, the unintentional contact with the abrasive could result in a rather painful injury or wound. Fortunately, most manufacturers of this combination belt and disc sanders equip their products with protective shrouds to minimise contact and exposure. You should look for belt shrouds that cover the top, bottom, and back of the belt. You never should go for a sander with the back and top uncovered because it could cause severe injury, especially when the belt is vertical in position.
Finally, the best advantage you can get from a combination of belt and disc sander is that it comes with enough power to take on even the most challenging home improvement maintenance and repair tasks. It is not merely about horsepower and amperage ratings since the tool is ingeniously designed for efficient distribution and transfer of power.
