Who we are and what we do?
At Bestdrilladvisor.com, we have developed a unique rating system (BDA score) to help us rank drills from the most popular and highest value products on our site to the least-liked ones. BDA score rates each product on a scale of 1 to 10 in three different categories: popularity, price to value ratio, and technical specifications. The products’ overall BDA score is calculated from the average of these three values. In each category, we take into account different specs like a number of reviews, price range, accessories, number and capacity of batteries, UWO, speed settings, properties of the chuck, impact rate…etc. This is all done on a spreadsheet, where all BDA scores are calculated automatically after filling the necessary input data. We are engineers, so we know how important it is, to look at quality data in order to make the right decision. At Bestdrilladvisor.com we do the objective evaluation for you, so you can be sure you get the best out of your purchase.

Frequently Asked Questions
How do I choose a powerful drill?
The efficiency of a drill is highly dependent on the torque it produces. The higher the value, in other words the more powerful your machine will be, so it is less likely to get stuck while tackling tasks such as driving larger screws or drilling holes into harder materials like drywall or wood. In order for you to have greater control over what you are doing without worrying about whether or not your tool can handle it (such as being able to drive large screws in), consider tools with high torque and UWO that match up well with those needed by any given project at hand.
Which is better: brushless vs brushed motor?
Brushless motors are better than brushed units due to reduced maintenance, improved efficiency, and less generated heat. As you would think, brushless motors don’t have carbon brushes, which would wear away and have to be replaced from time-to-time like in brushed motors. Also they come without commutators, instead they have electro-magnets and an on-board electric circuit, which provides more precise commutation than traditional commutators with carbon brushes. The last difference is, that the locations of the magnets and coils are also reversed. The permanent magnets, so called stator, are on the motor shaft and the copper coils of the armature, so caled rotor, are around the shaft in a fixed position. High-end power tools now use brushless technology because of the many advantages over traditional motor types.
