Bit Drilling- Points to Remember

An integral part of any set of tools, and any DIY project for that matter, are the drills. There are several different types of drills, and in this article we will briefly review some of the more common types that one might come across. This article series is in direct relation to flat track hardware installation for DIY’ers.

As mentioned, there are several different types of power drills one might encounter when working on their do-it-yourself project. But what is a drill exactly? How do you define it? Well, a drill is a rotary tool that is fitted with an attachment at one end for one of two purposes: cutting, or driving. An example of a cutting attachment would be a long spiral bit used to put a whole in a wood stud. A drivin attachmen would be like a small Philips bit used for driving screws.Find expert advice about bit drilling.

Generally speaking drills can be divided into two groups, manual and power. While there are several types of manual drills that one might use from time to time, the more common group is the powered drills, whether they be corded or cordless. First let’s address corded vs cordless drills.

Pistol Grip (corded) vs Cordless
Pistol grip drills are more powerful than their cordless brothers. Their internal workings, specifically the gears and motors, and much stronger than those you would find in a cordless. This is true of all power tools. Typically when the job calls for heavy cutting, drilling, sawing, etc., you want to stick to your corded tools.

So why even have cordless? Well, most of the time with drills you won’t be needing them for heavy duty applications. Having a cord trail out of the back all the time can be cumbersome and intrusive, especially when working in restricted space such as walls and ceilings. Also going cordless increases your mobility and speed. Overall, the cordless is going to be the more common option

Cordless drills
With the cordless drills, you’ll typically encounter two types: regular drills and impact drivers. Regular drills have a constant drive with variable torques. These are often used with cutting bits. Impact drivers are excellent for driving screws into different materials. When the drill reaches a certain resistance, the motor begins to deliver rotational blows to help continue driving the screw into place while at the same time resisting cam out. “Cam out” is when your drill bit strips the inside of a screw, and occurs most commonly with Philips screws.

Hammer drills
Hammer drills are among the corded drills. These are often used for drilling masonry. The most common example of a hammer drill that people would readily recognize is the “jack hammer.” Hammer drills are like normal drills with a rotary action except for one major addition; they are equipped to deliver a hammer action as the bit spins. The hammer action drives the bit forward and backward, aiding in the bit drilling down into the concrete.

Other drills
In addition to these, there are several other drills that exist, but most of those the typical DIY’er won’t ever encounter. For example, when installing flat track hardware, you’ll typically only use cordless drills. In some cases, if you’re installing the barn door hardware door guide into a concrete floor, you may need a small hammer drill to create pilot holes in the ground.

Other drills range greatly in size and application. They can be as small as what your dentist uses to clean out cavities, all the way on up to massive earth coring drills. Their mode of operation varies as well. Dental tools need to rotate at an incredible speed, faster than what any electric motor could handle, so they are driven by compressed air. Large coring drills need more output in typically harsher environments than is suitable for electric motors, and so these are often powered by small combustion engines within the drills themselves.
