When you need to drill into wood, you can make sure you get the right bit for the job. Different types of bits have different features. Hardness, shape, point angle, and price are just a few things to consider. Choosing the right tool will help you finish your job quickly and efficiently.
Hardness
The hardness of metal drill bits and wood drill bits is determined by the material they are made of. Metals, such as steel, are harder than woods and plastics, and therefore have higher resistance to drilling. On the other hand, soft materials, such as wood, are not as hard, and are thus easier to drill. The hardness of the bit is also related to the speed and force with which it is driven.
Choosing the right drill bit for your task is crucial. The hardness of the bit will determine whether it can penetrate through the material or not. Generally, a 118-degree bit will puncture through soft material, but it is dangerous to use on metal. Harder materials, such as steel, will require a 135-degree bit. The steeper the cutting angle, the more likely the bit is to wear out. However, this type of bit will help you drill repeatedly into tougher materials.
Shape
A wood drill bit looks similar to a metal drill bit, but there are important differences between the two. Wood drill bits are usually made of wood and do not have coatings, while metal bits are coated with titanium, cobalt, or black oxide. Metal drill bits can be identified by their color, which is usually black or dark gray. A wood bit has a silver or silvery sheen, and is suited for drilling through wood, masonry, and plastic.
Drill bits of either material are useful for drilling a variety of materials, though wood drill bits will probably be the most effective if you’re drilling metal. A metal drill bit will wear out quickly and may damage a wood object.
Point angle
A wood drill bit and a metal drill bit both have different point angles. The angle of the point of a drill bit dictates how the bit cuts the material. The angle is larger for soft materials, and shallower for harder materials. Choosing the proper angle can affect your hole shape, wear rate, and wandering.
The point angle is important because it determines the amount of support that the cutting edge gets. If the angle is too large, the bit will cut more aggressively, leading to bind and wear. The point angle also determines the amount of lip clearance. A wood drill bit with a shallow angle will have less lip clearance than a metal drill bit with a steep point angle.
Cost
When choosing a drill bit, it is important to know the difference between a metal and a wood bit. Metal bits are made of high carbon steel while wood drill bits are made from low carbon steel. Choosing the right drill bit for the job will make the job much easier and more accurate.
Wood drill bits are made specifically for drilling holes in wood. They feature spurs in the center to help keep the bit from wandering. Wood drill bits are great for drilling small holes in wooden objects and do not leave splinters or splits. However, the shape of the spur makes it difficult to sharpen them.
Metal drill bits are made from high-speed steel with a wide angled point. These are very versatile, but are also expensive. If you are going to drill soft aluminum or steel, you should get a high-speed steel drill bit. However, it is important to know that these are for industrial use only, and are not intended for home use.
Choosing a quality bit
Choosing a good wood drill bit is crucial to drilling holes in wood. You should carefully match the size and type of the bit to the material, depth, diameter and volume of the hole. This will increase the life of the bit and enhance productivity. You will use fewer drill bits to accomplish the same work.
A good wood drill bit should have high durability. Its high efficiency is another important factor to consider. A good wood drill bit will help you save a lot of time and effort. However, a poorly made drill or a wood surface with a hard surface can cause slow cutting.
