We've given this list a major refresh in our last update, dropping a few items that are no longer on the market and adding numerous sets from reputable manufacturers.
The top dog on the list, the Accusize Industrial Tools N10, is one of those newcomers. Its mid-tier price is justifiable because of the high quality of the drill bits and the well-made, nice-looking case.
An annular cutter set paired with a magnetic drill will shave a load of time off the tedious, often repetitive task of boring holes through metal. For those who work on deadline or have a limited amount of time to spend in the shop, switching over to these cutters from slower, more cumbersome tools is a wise move.
The standard annular cutter is made from high-speed steel and is capable of drilling through most of the material you are likely to come across. You are also able to resharpen them using a grinder.
However, in situations where you need to put a hole in harder or more abrasive material, consider the Bluerock 6 Piece TCT set, which has bits with tungsten carbide tips. Because the tips are a separate component, usually glued onto the bit, they are more prone to breakage and their use is not recommended on more routine, softer material.
Not only are these annular cutters sharp and designed to spin at a high RPM, but the metal ribbons of waste they produce can also be very sharp. Please observe all safety precautions when using them.
