What to Look for in a Drill Bit Set:
You need to use different bit sizes for different applications. Here are some key factors that you have to check out while shopping for the drill bit set. Take a look at them to know what are those factors….
1. Material:
There are different materials used to construct the drill bits. Based on your work application, you have to select the type of material to use. Have a look at some common materials used to build the drill bit set. High-Carbon Steel (HCS) Bits – With its properties conferred by tempering and hardening the material, it is considered durable compared to low carbon steel bits. These are used widely on metal or wood. If gets overheated (due to frictional heating when drilling), then they lost its temper and thereby results in a soft cutting edge. So, prevent it from overheating or allow it to cool down for a couple of minutes. Soft Low Carbon Steel (LCS) Bits – They are used widely to drill wood and are cheap & affordable. But unable to grip an edge properly and need to sharpen them quite often. It is suitable to work with softwoods, and in case, if done working with hardwoods, it can lessen their lifespan. So, never attempt to use this bits on hardwoods. High-Speed Steel (HSS) Drill Bits – It is a form of tool steel, which is hard and has more resistance to heat compared to HCS. It is used to drill fiberglass, soft metals, and wood at superior cutting speeds compared to carbon steel bits. This makes to replace the carbon steels in large quantities. Cobalt Drill Bits – They are made by combining cobalt with steel alloy to create a super-strong drill bit. They can easily grip their hardness even at higher temperatures. It is used widely to drill hard materials like stainless-steel. Yet the cobalt steels are more fragile (not durable) compared to standard HSS. Tungsten Carbide – These are extremely hard and can virtually drill all materials when holding an edge longer than other bits. Though it is expensive, yet more brittle than steels that makes it to use for drill-bit tips. Thus, they are used exclusively for drilling through masonry and ceramic tile, as the bits brittle nature make them more susceptible to breaking.
2. Drill Bit Coatings:
After knowing about the construction material of drill bits, you should know about its coating. Here are some commonly used drill bit coatings, which enhance the lifespan and the working condition of these drill bits. Black Oxide – It is a cheap black coating, which offers heat resistance, lubricity, and corrosion resistance. This coating will increase the life of high-speed steel bits. It is an ideal option to use in wet or humid conditions and can be suitable to use with most surfaces like thin metal (copper sheeting), wood, and fiberglass. Titanium Nitride (TiN) – This hard ceramic material is used to coat a high-speed steel bit (a twist bit) that extends the cutting life by 3 or more times (sharpens the tool). After sharpening, this leading-edge coating will provide improved cutting. So, the titanium-coated HSS tool is used on fiberglass, hard plastic, wood, and soft metals like aluminium, and lead.
3. Size:
The shank and the point are two common sizes to be considered when shopping for drill bits. Check out the difference between these two sizes and which one suits best for your requirement. Shank – It is a part of the bit that fits into the drill’s chuck. All you need is to select the bits with shanks that is equal to or smaller than the drill chuck. Standard chuck sizes will be 1/2-inch on heavy-duty drills, 3/8-inch for standard drills, and 1/4-inch on light duty drills. Point – Drill bit sets come with a wide range of point sizes and this pointed end of the bit is a business end. Most DIYers noticed that 1/16-inch to 1/4-inch drill bits are quite enough to perform various household tasks. While dealing with tougher drilling conditions like carpentry, construction or any major household repairs, then you have to add some larger bit sizes to the tool. The size range will include 3/8-inch, 5/16-inch, 7/16-inch and 1/2-inch.
4. Drill Bit Type:
There are various types of drill bits that you can differentiate by their intended use. Have a look at a few common types. Twist Drill Bit – It is a standard bit with a pointed cutting tip that features fluted sides to eliminate waste while drilling the hole. So, this twist drill bit is an all-purpose bit used widely for household purpose and used on plastic, wood, and thin metal. Brad Point Drill Bit – It is a fluted bit designed to use mostly on wood. This features a spiral grooves/ flutes on its sides and a sharp spur on its tip. Here the flutes used to grip wood chips to remove from the hole to drill, and the sharp tip will help to position the bit in the correct spot. Thus, it results in a spotless hole. This type of bit will speed-up your work, especially in jobs requiring a high level of accuracy. Forstner Drill Bit – Alike a brad drill bit, it features the sharp tip spur used to drill mostly on wood precisely. Yet the bit’s body is designed for flat-bottomed hole drilling, which won’t let the drill bit go all the way through the wood. These bits are generally used to make holes to grip dowels (not screws). They are found frequently in the construction of cabinetry and premium furniture. Countersink Drill Bit – This specialty bit designed to form a broader opening of a trial/test hole at the screw head’s top (countersinking). It is mostly used on wood rather than other materials, as this drill bit will let your enclosure the closure deep enough, which makes the head not to protrude overhead the material’s surface. Auger Drill Bit – It is long, twisted ribbon-shaped bits with a screw-shaped tip, used to pull the rest of the bit into the wood. Its unique design will allow the user to aid for a much cleaner cut by removing the material. Spade Drill Bit – This spade bit (or Paddle Bit) has a flat blade design meant for cutting large holes (of 1.5″) and a tip spur for precise drilling. Generally, we use this bit for drilling holes over wood studs for running wires and lines for proper water supply. Step Drill Bit – With its pyramid-shape, this step bit used mainly to enlarge the present holes, and also used on thin materials like sheet metal or sheet plastic. One can find on the bit labelled by the manufacturer along with its conforming size of hole drilling. You can replace the countersink bit with this type of drill bit, simply by wide-spread on the top of a hole to break the clasp head. Hole Saw Drill Bit – It is used widely to make a large hold in ceramic tile, thin plastic, wood, and supplementary sheet goods. This bit comes in two parts – a mandrel (shaft) for attaching to bit, and the bit (a cylinder having a sharp, saw-like teeth). Thereby get fits perfectly in the drill. Masonry Drill Bit – It delivers a quick hammering action and durable construction, which makes it use frequently for materials like concrete, and bricks and thus considered a staple for most masonry work. It is coated with tungsten carbide and bonded to a spiral shaft made of steel.
5. Number of Drill Bits:
Generally, the numbers of bits in a set will matter most, why because a set with a higher number of pieces will allow you to handle different types of drilling with the drill power tool. So, make sure to compare various models along with their options. Finally, select the model having a different and higher number of sets. In case, if not knowing what numbers of the set will suit best for you to purchase, then ensure that the package you purchase should offer at least 14 – 21 drill bits. Also, most experts recommend you choosing the highest number of drill bits, as they offer a lot of options, better precision, and flexibility to you while drilling and polishing things.
6. Accessories:
You can find some accessories included with some drill bit sets out there. They include things like carrying cases that are quite handy for easy carrying and storing your drill bits. On the other hand, you can end up losing some of the drill bits if you are not using a case to store them properly. While most of these drill bit cases are made out of plastic, some of them may use aluminum to construct, which makes the carry case sturdier and more durable.
7. Durability and Warranty:
Since we use drill bits to drill holes into all kinds of objects, thus it makes sure that they are quite durable and sturdier. As a result, a lot of drill bits use tungsten carbide and titanium coating for their construction. This makes them highly durable and easy to last longer without any issues. Mostly these drill bits are considered as accessories or replacement parts, in which most of them won’t come with a warranty. But you can find a few drill bit set options out there that comes with a 1-year warranty. Since these drill bits can last for a longer period, you can easily pick them to have worry-free usage. Also, check out the reviews, and ratings, along with the customer service provided by the manufacturer of a particular product before making its purchase.
