Magnetic drills are portable tools suitable for drilling structural steel and similar metals. They are widely used in mining environments, shipbuilding or welding workshops.
Drill bits for every need
Drill bits are found in a variety of sizes, shapes and materials according to the needs of the job. In order to choose the right one, you must consider the speed you will need for drilling, material hardness and the type of tool to be used.
Although most drill bits have straight shanks, drill bits with brace shanks are often used for high-strength drilling. Many include a hexagonal shape with patented quick-release system. The drill bit diameter / length relationship is generally 1: 1 and 1:10, although there are also much higher ratios, keeping in mind that technical challenges for a good job will increase with ratio.
There are many the materials used for manufacturing drill bits and they depend on purpose. For example, hard materials such as carbides are much more fragile than steel, so they tend to break more easily.
There are affordable steel drill bits whose resistance is very low. These need to be sharpened frequently because they are low in carbon and are meant for woodworking. You will also find those with high carbon content, which provide greater hardness and allow metal drilling. Drill bits with carbon may overheat but will continue to perform properly.
Drill bits with steel and cobalt alloys are available on the market and they will keep their hardness at high temperatures; widely used in stainless steel drilling.
The polycrystalline diamond-coated drill bits are extremely resistant to wear. The drill bits made with this material (diamond powder on the tip) are used in the car industry to drill abrasive alloys of aluminium or carbon-fibre reinforced plastic.
How to know which drill to buy?
In order to choose a drill you must think about certain aspects that will help you make the best decision. It is not enough to compare what is on the market and how cheap you might find them to be. It is necessary to count on a definitive guide to buying in order to make the best acquisition, one that is really functional and satisfies the user’s needs.
The first thing to bear in mind is where and when it will be used. It is pointless to invest a large amount of money in a drill that will not be used properly.
The chosen drill must be practical, one that can be operated in an effective manner and that will fulfil several functions: carpentry work, metal or steel perforation.
Although the price is important, you can still purchase very economical models with all the needed features and functions. However, you should not hesitate and always buy the best and well-known brands such as Bosch, Black and Decker, Milwaukie, Makita or Dewalt.
Ergonomics is also a very important feature. If the user feels uncomfortable while using the drill, it will surely bring discomfort and more fatigue than necessary. It is important that the final user is the one who evaluates whether or not the use of the equipment will be feasible.
It is essential to know the opinions or advice given by people about certain models and drill brands as they will help us greatly when choosing the one that best suits specific needs. It is beneficial to have access to first-hand evidence than to be disappointed after buying the wrong one.
