We often encounter many problems when buying tools, such as how to choose the commonly used drill bits? Today specifically for you to identify tungsten steel drill bits and white steel drill bits in the end how to distinguish? Specifically, you can distinguish them through the following five points.


1. The difference in weight. It is simple and straightforward, because the tungsten steel drill bit is heavier than the white steel drill bit with the same specifications, so you can distinguish it by weighing it in your hand. This is. This is one of the easiest ways.


2. Distinguish from the colour, tungsten steel bits have a serious appearance of being bright and ebony, so they are also called tungsten steel. White steel drill bits are bright and white in appearance.


3. Distinguish from the coating, tungsten steel drill bits are coated with purple colour, while white steel drill bits are pure black and blackish or dull yellow.


The difference in price is that tungsten steel drill bits are expensive, while white steel drill bits are much less expensive, usually 1/3 of tungsten steel drill bits and 1/10 of Shenzhen.

5. The difference in use, tungsten steel drill bit cutting speed, long life, white steel drill bit easy to wear, low life.


Tungsten steel drill bit material, tungsten-containing alloy tungsten steel products contain about cobalt between 10%-18%, tungsten steel belongs to the hard alloy, also known as tungsten titanium alloy. With a hardness of HRA 90-93, it is second only to diamond. Because of this, tungsten steel products (commonly known as tungsten steel watches) are not easily worn out. It is commonly used in the manufacture of turning tools, various drills and milling cutters, glass and tile cutters, etc. It is hard and not afraid of annealing, but is relatively brittle. It belongs to the list of rare metals.


Tungsten steel drill bits and ordinary drill bits or white steel drill bits can also be identified by sparks, grinding on an ordinary grey grinding wheel, the sparks of tungsten steel drill bits are dark red, it is difficult to grind, high-speed steel drill bits or white steel drill bits sparks are brighter. The tungsten steel drill is brittle, and when it falls from the hand, the edge will crumble off a piece, while the white steel drill is tough and does not easily crumble. 


Tungsten steel drill bits have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500°C and still have a high hardness at 1000°C. Tungsten steel drills are tools used to drill through or blind holes in solid materials and to ream existing holes. The main types of tungsten steel drills we commonly use are twist drills, flat drills, centre drills, deep hole drills and nesting drills. Although reamers and countersinks cannot drill holes in solid materials, it is customary to classify them as drills.
