Some of them are for professional use; cost more and some are very handy, costs less yet performs all household repairing. To narrow down your searches we shall be discussing their features, functions depending on your purpose of use. This buying guide is going to be an assortment of all the things you must consider before you just go and determine buying something without proper knowledge.
1. Types of Drills
Drills come in different varieties depending upon their functions.
- Drill Drivers: The most basic type of drills with dual functionality – drills holes and acts as screwdrivers (for loosening and tightening screws). Useful for simple tasks like putting up shelves or assembling DIY furniture.
- Combination Drills: These slightly advanced drills have triple functionality – drills holes act as screwdrivers and also acts as a hammer drill for very hard surfaces like concrete.
- Rotary Hammer Drills/SDS Drills: SDS (Self Direct System) drills are meant for heavy-duty drilling through concrete or masonry. These are slightly bulkier but are multifunctional and can be used for chiselling too.
- Hammer Drills/Percussion Drills: These are the most advanced and powerful drills, especially suited for extra heavy duty drilling through hard rock or masonry. The rotation plus drill functions work together, making it more powerful than SDS drills.
2. Corded Drills Vs Cordless Drills
The first and foremost decision to make while buying a drilling machine is between corded and cordless. They both have some advantages and disadvantages, depending on your usage.
- Cordless drills– they are more convenient to use. They are lighter than the cordless one and offers high mobility. You can use them anywhere without the struggle of power cords. You can avoid tripping over cords so they are quite safe.
The high powered ones (18-24v) can be heavy or even heavier than the corded ones. Usually, 12-18v is enough for all kind of homeowner’s works and 4-8 volts can perform lighter duties cordless screwdrivers.
A cordless drilling machine’s battery requires charging from time to time. You may want to keep a separate battery so you can work while it gets charged and you don’t run out of power that way. Their battery life is also limited. The costliest will last up to 2-3 years max.
Be careful with the battery they come with, Lithium-Ion batteries are always superior compared to Nickel-Metal-Hydride batteries. They are more powerful, lasts long, contain less harmful metal elements. Also, look at amp-hours, more amp-hours and more volts batteries run a long time but the battery life will always depend on how much it functions, what material it works with and battery charge level.
- Corded drills- they are more powerful and often lighter than cordless drills with similar functionalities. Steady power supply runs the device for a greater time and never stops because of low battery charge. An amp-hour rating denotes the power of a corded drill. They are often cheaper than cordless drills. But again the power cord gets in the way restricting the area of working and portability. You will require an extension cord when working with a corded drill machine.
Chunk is the metal shaft of a drilling machine that holds the bits (the metal part that makes the hole) together. They come in different types and sizes.
- Sizes of chucks- 1/4, 3/8, and 1/2 inch are the standard sizes. 1/4 chuck size is suitable for light duties, 3/8 is the most popular size, ideal for almost all work around the house and fits a wide range of different sized bits. However, if you want big diameter drilling machine for heavier applications, go for 1/2 inch chunks, as 3/8 inch drill will not accept several larger bits.
- Types of chucks– there are two types of chucks in a drilling machine, namely Keyed Chuck and un-keyed chuck. They keyed chuck uses a mechanical key to loosen and tighten the drilling machine bits and in un-keyed chucks, you have to hold the chuck in your hands and the bits get tighten as you power the drill.
A good drilling machine should possess the power to penetrate through masonry and other hard surfaces. Average drilling machines have a customary 500-watt power, they can perform almost all household repairs, but you can buy lesser power machines with 450 watts if your needs are limited. While you will get some more powerful machines ranging between 600-700 watts for professional use to drill through metal substances.
5. Size and Weight of the Drill
A drilling machine is a hand-held tool used for boring holes in various materials. Hence, the size and weight of the drill are important factors while choosing which product to purchase, depending on your requirement. Smaller ergonomic drills are more comfortable to use around the house while bulky drills are more suitable for heavy duty usage.
6. Other Important Features
- Reverse– it is used to get the stuck bits out of the surfaces. If your bit gets stuck inside the woods or concretes and you can’t pull it out by strength, put the machine in reverse mode and it will come out easily. It is a must-have feature in case you are not using the machine only for driving screws. A keyless chuck will have reverse by default but for others, check properly before buying.
- RPM & Impact rate- more the RPM (revolution per minute) level smoother the drilling becomes. Also, drilling machines with better impact rate ensures better penetration. Most of the devices match the standard RPM level and Impact rate, but if you want top-notch functionality you should consider these factors.
- A Torque Clutch- it is a must look-into feature if you use the machine for driving screws. With the help of a clutch, you can select maximum torque level after which the drilling will stop. This is used to prevent from driving the screws too deep into something. Low torque and high speed is for drilling soft materials and high torque lower speed for hard materials.
- Gear- for multipurpose use go for a driller with more than one gear. First gear works well for driving screws and the second one is for actual drilling with higher speeds.
7. Additional features
While buying a drilling machine suitable for your use, look for additional features as hammering mode or screw-driver mode. A hammering mode is useful to crack some surfaces while a screw-driver mode is ideal for tightening the screws more effectively. It completely depends on what purpose you will be using it.
8. Drill or Kit:
The whole drilling kit comprises a bunch of tools for all kind of repairing works. It is much expensive, whereas a single drilling machine costs less as it comes with only some bits, key, chunks and sufficient for household requirements. First, decide which one you really need and save yourself from splurging over non-required things.
Most of the drills with basic features cost around 200, some with added features for expert use can cost you 2500 or above. If you are not a professional, these may not work for you; consider buying the basic ones instead. If you need to buy the full kit along with hammer, pliers and wrench it will cost not less than 5000 and sometimes more.
10. Brand & Warranty
A good brand comes with the superior build quality, reliability and top-notch performance. A reputable brand will always offer a decent warranty period. While purchasing drilling machines try to go for the ones which provide at least 6 months of warranty.
Frequently Asked Questions
As it is a power tool, there are simple ways to maintain your drill. The basic step is to keep your drill clean and free from any type of leftover dust and debris. It may not be an easy task as drills are used in so many different scenarios and applications. You can use a blow gun to blow away any debris and fragments. Alternatively, always check the carbon brushes inside the tool from time to time. Carbon brushes are a part of any power tool which depletes with age and use. You can use a slotted screwdriver to check if it is fine
This is a very common thing among drilling machines. If you get a burning smell while using the drilling machines, it basically suggests that the motor is being overly stressed or overheating. This is applicable not only in drills but also in any power tools. This can also be an indication that the drill is being used on something that it isn’t meant for or used incorrectly. This occurs when the motor’s fans are not able to cool the motor windings fast enough leading to overheating and melting of varnish coating. It is not an alarming situation though. If you get the smell again, just withdraw it from whatever you are working on and leave the machine running. This will give time to the motors to cool down the windings and you can start working again as usual.
To prevent any type of overloading on your drill, you must ensure that you reduce the cutting load. It can be done in the following ways:
i) Use one or more pilot drills.
ii) You can use lubricants for cutting and cooling.
iii) Maintain quality standards and use sharp drills and accessories.
iv) Slow down speed or change gears.
v) Don’t force the drill; let the drill do its work on its own.
vi) Regular cleaning and maintenance
This is a very common issue among users who are new to drilling. Most drills have a reverse option. If you are stuck on a wooden or a concrete surface, it is advised to use the reverse option in drills. What it does is that, it simply reverses back you to the initial position. So, you don’t have to pull anything out, the drill will pull itself out smoothly and you will never get stuck. Almost all drilling machines have this option, but you must check it on your user manual.
If your drill isn’t working right, you must enquire if your tool is still under warranty. If it is indeed under warranty, go to the place of purchase immediately and they will do the required things. If it isn’t under warranty, unfortunately, it is better you go to any agent for repairing or buy a new drill altogether. Most people choose the latter!
A basic 450-500 watts drilling machine is perfectly suitable for any type of household work like drilling through wood, driving screws and simple repairs. Keep in mind; go for something that is ergonomic and easily portable or else it will be very messy and cumbersome to do any work. Fortunately, most of the machines these days are designed well and comes with a lot of useful features.
