Everything You Need to Know About Buying a Drill Machine Online
Posted by Shoppersgreed on December 24th, 2014
No modern tool box is complete without a drill machine. A drill is one of the most indispensable hand-held power tools every handy person and DIY-er must have, especially when you do much wood and handy work. Purchasing the correct type of drill is crucial, otherwise you will have trouble drilling the right size and type of holes for your repair, maintenance, or construction projects.
There are two major types of drill machines—cordless and corded. Generally, cordless drills are fit for light tasks and typical repairs or general DIY. They are convenient for general home and workshop use because they are light, portable, and easy to operate. Corded drills, on the other hand, pack more power and are better built for more demanding and strenuous tasks. Outside of their cordless and corded configurations, drill machines also come in many other modes and types such as percussion drills, rotary drills, and hammer drills.
Cordless drills are typically powered by rechargeable battery packs, often concealed in the hand grip or located in the butt of the drill. Freedom to use even when there's no direct power source is one of the most important advantages of cordless drills. The lack of a trailing cord also allows freer movements, especially when trying to drill holes in restrictive places. Corded drills, however, have slower rotation speeds than corded drills, which often use more power. They also produce more vibration, usually resulting in sore muscles after long periods of use.
Corded drills are designed to provide higher drill bit rotation. They are also suited to perform a wider range of tasks than their cordless counterparts. Rotary drills are the most standard type of cordless drill, with higher rotational speed than that of cordless, percussion, and hammer drills. They are suited for light to medium duty work, such as general household repairs and DIY projects. They are, however, not suitable for masonry work or for working into hard and tough materials, like concrete.
Rotary hammer drills are much like rotary drills, only, they produce a hammering action on top of the drill's typical rotation. They are better suited for heavy-duty tasks and drilling into masonry and concrete. They can be used as a standard rotary drill, without the hammering action or you may also leave the hammer function on and turn the rotary mechanism off, as needed.
Percussion drills work the same way as rotary hammer drills, except that the rotary and hammer functions cannot be used separately. This is because the drill's hammering action is triggered by the chuck's rotation.
