Whether you are a professional engineer who prefers to go for cordless drilling or a student on vacation who is a DIY hobbyist, having the perfect drill bit is vital to your project.
Drill bits come in a variety of sizes and shapes and can be made of various materials including titanium, steel, cobalt, etc. Which type of coating to be used depends on the type of project you are working on. For example, a hard coating such as that of carbide stays sharper for longer but is more brittle and thus can be easily broken.

Types of Drill Bits:
High-speed steel is a commonly used material for bits which is an economical option and can be used for drilling into wood, plastic, and soft steel. It is more durable than low-steel carbon but once it gets heated it can lose its temper.
Cobalt-steel alloy drill bits have 5-8% cobalt. The 5% Cobalt alloy is known as M35 grade and the 8% alloy is called as M42 grade. They have a greater ability to withstand heat. They can easily be drilled into hard materials such as bronze, stainless steel, and more. However, they are more brittle than standard high-speed steel.
Tungsten Carbide drill bits are extremely hard and thus can easily drill into hard metals and other materials. However, these bits are expensive and more brittle than high-speed steel thus have a higher tendency of breaking.

Best Drill Bits Coatings
Different material is used for coating drill bits and it increases the durability.
Black Oxide coat is usually used on drill bits as it is inexpensive and provides corrosion resistance. It also aids in heat resistance and lubricity.
Gold Oxide is often used to coat bits that require more resistance to heat buildup. These bits are mostly designed for three-jaw drills.
Titanium Nitride coating lasts more than 6 times longer than high-speed steel. This coating increases friction thus making the edges stay sharper for longer.

Frequently Asked Questions:
1.Why do my drill bits keep on breaking?
Breakage is usually caused when you do not clear the chips, flex the bit, be too hard with them (as in applying too much pressure) or use low-quality drill bits.
2. Do I need special bits for the hammer drill?
The majority of the hammer drills have a three-jawed chuck that can work with the twisted drill bit as well. However, masonry drilling needs a specific type of bits.
Concluding Note:
Building something takes effort, time, and money. To make it last longer and stronger beware of the type of material you use. Drill bits are worth investing in as they would enhance the structure and increase the life of your project.
