What are the different types of Rotary Tools and what do they do?

Rotary power tools use an electric motor which is powered by either battery or mains supply to enable the user to do a range of tasks including cutting, grinding, sanding and engraving. They are used by professional and DIY amateurs around the globe to cut down on the amount of manual labor required to do a job.

As with all modern appliances, these tools come with a wide range of differing performance levels, functions and optional extras. All good rotaries should include variable speed controls, a universal tool attachment option, a good level of torque and a high tool end Rev per Minute or RPM.

Rotary tools differ in these main areas:

  1. Rotary Speed is measured in RPM and will be one of the first things that you see when reading a product description. The description will give a maximum and minimum value for RPM, so ideally the lower and higher these two respective values are the better.
  2. Torque is one of the most important parts of a rotary tool. Anyone who has even had to do some heavy metal grinding will know just how frustrating it can be to have a tool with a poor level of torque.
  3. Attachments are something definitely worth checking on. Though getting a good number of attachments with your purchase feels great, you also need to consider that at some point they will need replacing.Try to make sure you are getting a universal attachment tool so that you can buy off the self-tool bits to replace them. Many companies have specially designed collets to hold the bit ends in place that are not universal. They do this to try to restrict the chance of people using other companies’ products in an effort to increase their own revenue.
  4. Cases are something else that you should keep an eye out for as not only do they help to carry and protect your rotary but they are also great for storage.

How do I know which is a really good quality rotary?

It can be a real nightmare trying to tell the good from the bad as far as electronics are concerned. Most people make the somewhat correct assumption that sticking to the top brands will help you to avoid buying something that turns out to be a total waste of money.
We have long since accepted that most products on the market will have been made in China, but in recent years that has seen the market flooded by low cost, often low-quality electronics. However, there are many good low-cost products that are made by unknown brands mixed in with these bad ones. Unfortunately, Chinese products have already gained such a reputation for poor quality that most people skip these perfectly good power tools in favor of well-known brands.

There are a few things that can help you find a good quality power tool without the need to resort to costly trial and error.

  1. Brand and reputation
    As far as electronics go, a well-known brand is not a guarantee of quality, though it does give some good indications of a general level of quality. Brands like Bosch, Dremel, Black & Decker and DeWalt are a good bet so far as the design and quality of the product are concerned. Cheaper brand electronics will often produce inferior products though increasingly this is not the case. We strongly advise if you are unaware of a brand’s reputation that you do a background search to learn more about it before you buy one of their products.
  2. Product feedback
    Product feedback that has been written by customers who have recently bought the item is arguably the best source of information regarding a product’s overall pros and cons. Finding a site that offers a good level of customer feedback is a good idea as it will give you more viewpoints on which to base your decision.
  3. Reviews
    Reading some good quality reviews that are well-researched is also a really good idea. Since most reviewers are experts, they are able to compare a range of different products in better detail to decide which ones are the best of the bunch.
  4. Safety Certificates
    It is advisable that you check to make sure that the product you are looking at buying has been certified as safe by the government safety organizations. In the United States, this is handled by the United States Consumer Product Safety Commission, that makes sure that all products adhere to the various safety regulations, like the National Electrical Code and the Consumer Product Safety Act.
  5. Warrantee
    You should always make sure that you are getting a good warranty with whatever product that you are buying. Since statistics show that the highest rate of failure of an electrical product occurs within the first year, it is really important to make sure what kind of warranty you are getting. Most products come with a 1-year warranty, but many manufacturers now offer 2 and even 3-year warranties giving you even more protection.
