Drill Bits Features and Considerations
Selecting the right drill bit for your projects is not an easy task. There are many options for materials, shanks, and tips to choose from. Here are the things you should look for when searching for the best drill bits for your project.
Drill Bit Materials
Different materials are used to manufacture drill bits depending on the application that is required. Hard materials like carbide stay sharper longer and are versatile. However, they are more brittle compared to steel. They are subject to breaking especially when the drill is not held at a constant angle to the material.
Here are some common materials:
Low-Carbon Steel Bits
These bits are affordable. They require frequent sharpening and do not hold edges well. They can only be used to drill softwoods. Working with hardwoods can shorten their lifespan.
High-Carbon Steel Bits
The bits are more durable compared to their low-carbon steel counterparts because of the properties conferred by tempering and hardening the material. If you overheat the bits by frictional heating when drilling, they will lose their temper and result in a soft cutting edge. You can use the drill bits on metal or wood.
High-Speed Steel (HSS)
HSS drill bits are sturdy and resistant to heat compared to high- carbon steel bits. You can use them to drill hardwood, metal, and other materials whose cutting speeds are greater than carbon-steel bits. These bits have replaced carbon steels largely.
Carbides can drill any material and are extremely hard. They can also hold an edge longer compared to other bits. The material is more brittle than steel and more expensive. They are used for drill-bit tips.
Cobalt Steel Alloys
These are variations of high-speed steel containing more cobalt and provide better heat resistance. They are used to drill hard materials including stainless steel and cast iron. They tend to hold their hardness at higher temperatures. These are extremely strong for tough projects. One major problem with cobalt steel is that they are more brittle than standard high-speed steel.
Drill Bit Coatings
Drill bits are equipped with sharp tips that require a coating to enhance their performance and versatility. The two most popular types of coatings include:
This is a hard ceramic material that can last six times longer compared to other bits. Titanium minimizes the friction on the drilling surface to offer cooler drilling. The coating is designed for the hardest and most demanding materials.
Titanium Nitride can be used with plastic, drywall, steel, and wood. It can also be used to coat high-speed steel bits especially twist bits to extend the cutting life.
This coating improves the lubrication and heat resistance of drill bits. It also provides corrosion resistance while increasing the shelf- life of high-speed steel drill bits. The inexpensive coating also offers protection from rust and water damage. It is best for drilling with plastic, wood, and certain metals.
Drill Bit Shapes and Angles
Majority of drill bits for domestic use have a straight shank while those for industrial drilling have a tapered shank. There are also other types of shank shape like the hex-shaped drill bits. Here are the most popular drill bits characteristics you will come across:
This angle provides the cutting edge support and helps create more aggressive cuts using less pressure than small lip angles. It’s important to note that the point angle is what is used to determine the right blip angle.
For instance, a flat drill bit is more prone to small changes within the lip angle due to the smaller surface area provided by the cutting edge.
This refers to the angle that the tip of the drill bit is equipped with. The correct point angle is determined by the material you intend to drill. For example, hard materials need a bigger point angle while a sharp point will be ideal for soft materials. Choosing the point angle of the drill bit is essential for creating the right shapes of holes.
This determines the twist rate while in drill bits. The twist rate is used to determine the size and rate of removing materials. A low spiral has a higher cutting speed and a high spiral removes bigger chips. The low spiral bits are used with materials that clog the drilled hole or materials like copper and aluminium.
Drill Bit Type
Various drill bit shapes make it difficult to know the correct type of drill bit. However, getting the right bit shape is easy when you know what you plan to drill and the material you intend to drill. Here are the most popular drill bits you will come across while shopping:
Twist Drill Bits
These are the most commonly manufactured drill bits nowadays. They are great for using on various materials including metal, plastic, and wood. The twist bits are also found in many variations and styles. They are also affordable and a staple in the bits market.
The twist shape is meant for cutting smaller holes instead of bigger ones. The only issue with these bits is that you will have to remove them while drilling. This is to prevent the material from clogging up the bit’s rotation.
Auger Drill Bit
These bits are usually the best choice for those people who want to drill larger or deeper holes in wood pieces. The shape is crafted to help remove bigger amounts of material when boring to ensure you drill consistently without clogging. However, this type of drill head cannot be used in hand-held power drills.
Countersink Drill Bits
These drill bits are commonly used with soft materials like softwoods and plastic. The bits are used to make counterbore or countersink holes to enable screw heads to fit in. Using them on metals is not recommended as they won’t function well.
Flat Wood Drill Bits
Also referred to as paddle or spade drill bits, you can use them to make flat surfaces at the bottom of holes. Their sharp pointed tips and flat blade shape make them easily recognizable and are perfect for use with wood.
The centred tip shape creates an accurate and continuous hole while drilling and helps you maintain your position. Splintering can occur while using these drill bits. However, you can avoid it by drilling from the other side of the initial hole has begun to splinter.
Masonry Drill Bits
These types of bits are perfect for breaking through tough materials like brick or concrete. They use flutes to remove excess materials and break the materials while rotating. Remember to remove any debris or dust between usages and allow them to cool down when drilling on tough surfaces.
Forstner Drill Bits
These bits are used in conjunction with a drill press to make flat bottom holes in pieces of wood. A drill press is meant to control the position and movement of the drill bit. The bit requires regular cleaning because it does not remove excess material as the twist bit does.
Spur Point Drill Bits
Also known as brad or dowel point tip, the bits drill straight due to the sharp central tip that is surrounded by elevated spurs. These bits are ideal for cutting accurate and clean holes through wood.
Hole Saw Drill Bits
If you want to create a big width hole, use these bits. The bit shapes are easy to recognize as they resemble a hollow cylinder that has jagged edges at the bottom of the edge. The hole saw drill bits are an excellent choice when you want to create wire holes or install doors.
Tile Drill Bit
These drill bit are great for installing tiles as they reduce cracking. They implement a spear shape to ensure you drill safely through brittle and hardened materials like tiles or ceramics.
Though these bits are a safer alternative, it’s advisable to use power drills at low speeds. Cracking can still occur. Use a good lubricant if you are using these bits to drill glass to prevent overheating.
Drill Bit Points
The shape of the bit’s point is another aspect worth considering because it will determine the materials it will be used with. Here are some types of point bits:
Speed Helix Bits: These bits offer long life and faster drilling and are the most aggressive bits available.
135 Degrees Point Bits: These types of bits are designed to be used with sturdy materials like stainless steel and metal.
118 Degrees Point Bits: The bits are crafted for use with wood, plastic and light metal.
Drill Bit Shanks
Drill bit shanks come in different shapes including:
Tri-Flat Shanks: These shanks ensure spinning does not take place under high torque loads.
SDS Shanks: The SSD shanks do not require to be tightened and are designed to be used with hammer drills.
Round Shanks: These shanks offer more accuracy by enabling you to centre the drill bit in the chuck.
Straight Shanks: If you are looking for shanks that are easy to center, the straight shanks are an ideal option.
Hex Shanks: The hex shanks have a hexagonal shape that ensures the tool grips the bit tightly for maximum torque.
Drill bits are a necessity at home and in the workshops of professional contractors. However, the most important thing you should check is the quality of the set and the intended use.
Some drill bits are for boring smaller holes. Others work best for bigger holes. Some are manufactured to drill holes into softer materials while others are used to drill into harder materials. So, inform yourself properly before choosing your drill bit.
