We have been getting a lot of questions on how to use a drill, so today we bring you a highly informative article regarding this question.
To some people, this question might seem really easy and unworthy of asking, but the truth is, nobody actually knew how to use a drill until he read a little article on its usage or got some tips from a friend, so away with the sarcasm and lets tear this topic apart.
Using a drill may sound quite easy, but frankly, it is not, especially when you consider the technical requirements and set-ups for using a particular brand and a particular model of drill. Drills are of 2 major types, the Wire Drill, which is basically a drill device attached to a cord that would be plugged to an electric socket for power, and the Cordless Drill, which is a portable high-tech drill, powered by a battery. Each is further divided into hammer drill and driver drill.
A drill is a valuable tool, largely because it is a versatile tool used for small jobs around the house like installing wall hangers for hanging pictures, and large project like building a deck or a wooden fence. It is also an absolutely essential tool anytime you have a lot of screws to drive. However, in other to use a drill for these different applications, there are some manual set-ups required. These set-ups give the drill the full functionality for a particular task.
Before using a drill, it is advised to wear a pair of safety glasses and gloves. The safety glasses and gloves are very essential because drill bits are often made of steel, this steel stands a chance of chipping off a very tiny part while at use and there is a big possibility of the chipped off part logging into the users eye, and resulting to a serious health issue. Abiding by this safety measure for using a drill is more profitable than knowing how to use a drill and every other tool in the world put together.
There are various controls on a drill, a particular drill could have over 4 controls that may be slightly different from the 4 controls on another drill. However, there are few controls which are found on every drill and these are the primary controls required for a complete drill operation.
1. The Drill Shift Lever
The drill shift lever (also known as the gear selector) is located at the top of the device. It lets you select between high torque and high speed settings. The high torque and high speed serve different purposes. The high torque adds force to the work and is often used for task requiring power and force, like drilling a hole on a metal, wood etc or driving a screw. While the high speed adds more speed to the work and is mainly used for very light tasks. So if you are working with a drill and the machine keeps stopping, just check to make sure you have it in the right gear.
Remember: High torque = Slow speed, and High speed = Low torque.
2. The Adjustable Clutch
The adjustable clutch is a numbered ring that allows you select how much torque or power the drill puts out. It is also called the torque control ring. In some recent models of drill, this ring also gives the option of hammer alongside the numbers, giving the user the choice to use a full hammer clutch.
3. The forward-reverse-and-static lever
The forward-reverse-and-static lever is a 3 dimensional switch located right behind the trigger, that determines the functional state of the drill. It controls the direction the bit rotates and is set to static when not in use, to lock the trigger and prevents it from been pulled. This static position is often referred to as "child lock".
4. Variable speed trigger
The variable speed trigger allows you control the speed. It is called "variable" because the harder you pull the trigger, the faster the machine goes. This determines how fast the drill bit turns.
5. The drill bits
The drill bits are the smaller tools attached to the tip of the drill, used for specific tasks. Bits come in different sizes and shapes, serving different purposes and requiring different drill settings. Some bits are used for simple tasks and require a low clutch setting, while some bit are for highly demanding jobs and requiring a high clutch setting. The type of bit to be used on the drill is determined by the type of chuck on the drill, a 1/4" X bit can only be used on a 1/4" X chuck and cannot be substituted for a traditional round-headed bit.
Doing the real drilling
To mount a drill bit, place it into the keyless chuck and turn the chuck counter clockwise to tighten. It is very essential to tighten up the chuck properly before drilling, because when it is tightened poorly, the bit might get stuck in the drilled hole and leave the chuck running freely, causing a lot of damage to the bit and sometimes to the drill chuck itself.
After mounting the drill bit, set the shift lever to the desired setting and turn the adjustable clutch to the desired position. REMEMBER: The shift-lever and the clutch setting are determined by that kind of task at hand.
Switch the forward-reverse-static lever to the forward position and you are ready to drill.
Position the drill and gently pull the trigger to start drilling, increase the speed gradually, and when the hole has been completely drilled, remove the drill and then release the trigger. It takes a person who really knows how to use a drill to this part. Be sure to remove the drill from the hole before releasing the trigger.
