Drills are versatile tools used in manufacturing and home repairs. Hand drills include the bow, gimlet, chest, and pin chuck. Hammer drills have a punching action, and cordless drills are available. Industrial drills are large and specialized, such as drill presses and gear head drills. Drills range in price and can be used for various projects.
Whether in a manufacturing shop or in the home, drills help provide invaluable assistance in creating and repairing a number of different products. Drills are one of the most commonly used power tools, with many different models accommodating a wide variety of bits. Over the years, different types of drills have been developed for various commercial and home uses.
As a hand tool, there are a number of hand drills that are still in common use. These are the bow drill, gimlet drill, and chest drill. Both bow and gimlet drills are useful for a number of different applications. The breast drill is sometimes referred to as an egg beater drill, due to the action used in the drilling process. A pin chuck is a precision drill formulated for use in jewelers’ detail work.
A hammer drill is very similar to ordinary electric drills used in the home. The difference is that the punching action is achieved with the use of a hammering action. If required, the hammer drill can be set to a more traditional setting, making the device multi-purpose.
Many standard home drills are now available as cordless drills. These drills use standard bit sets and work the same way as any core drill or rotary drill. Powered by a set of rechargeable batteries, there are cordless varieties of nearly every type of hand drill, even the specialized hammer drill.
Industrial drills are common in all types of manufacturing environments. Unlike home drills, industrial drills are often large pieces of machinery that can handle specific jobs. The drill press is often employed in the modification of machine parts, as well as in large-scale woodworking production. A gear head drill can provide a continuous drilling process as part of an assembly line production style. Milling drills use a belt-driven drill press that allows for simultaneous clamping and cutting action.
Drills can cost anywhere from a few dollars for a simple-to-use home drill to thousands of dollars for an industrial product. There is a drill for almost every type of application, as well as many drills that can be used for different types of projects.
