There’s an old sales ad saying “When individuals purchase a drill bit, what they’re truly purchasing is a hole”.
Common questions when choosing an appropriate drill bit:
In other words, while picking the correct drill tool for the job, it is critical to consider the hole you wish to make. What surface do you have to infiltrate? How deep do you have to penetrate? How many holes do you want? Utilizing the correct drill bit will give you the outcome you want.
There are numerous sorts of drill bits that can be used on various materials. For instance, when boring cement, a masonry drill bit is required which must be harder than it is sharp. When you drill softwood, strength is less significant than sharpness. Truth be told, when you drill wood with a masonry drill, the duller cutting edges which separate stone and solid surfaces so well will create a great deal of friction and tearing on the wood. Therefore, you should always get the right bit for the appropriate surface to create the desired hole.
Drill bits that are designed to infiltrate metal are an alternate sort of bit,. Like a wood drill bit, the need for cutting sharpness for metal is as crucial yet the drill bit itself should be made of a much harder material than a wood bit. Both are precision things yet at the same time have different attributes.
Know how to differentiate drill Bits?
Wood and metal drill bits tend to look alike. Wood drill bits are usually made from carbon steel or high-speed steel (for hardwoods). Metal bits tend to be HSS and can contain cobalt or titanium. Most drill bits are grayish/silver in color. Titanium drill bits are gold in color while Cobalt drill bits are a deep gray color, it’s very hard to tell the difference between wood and metal drill bits so it is imperative to refer to the manufacturers or the product provider. Likewise, in contrast to masonry and metal bits, the best wood bits are brad-point bits which have a center point and sharp outside cutting edges. Using a brad-point drill bit will allow you to make cleaner holes than can be accomplished by using a round or cylindrical style of bit. So take care to look at all the options available before proceeding. This way, you will consistently have the correct bit for the correct surface and can make a hole that is right for you.
Conclusion:
The best drill bit for wood is a brad-point drill bit made from carbon steel or high-speed steel (HSS). It has a center-point and sharp outside cutting edges. The best drill bit for metal is a regular-point (v-point) drill bit made of high-speed steel or cobalt steel. The v-point is ideal for metal because the tip of a brad-point drill bit would dull quickly. Masonry drill bits generally have carbide or hardened steel v-point which isn’t very sharp and is used to grind or tear the cement-type material.
