Basic Concepts of Drill Bit And Tungsten Carbide Drill bit

Drill bits are cutting tools used to create cylindrical holes, almost always of circular cross-section. Drill bits come in many sizes and have many uses. Bits are usually connected to a mechanism, often simply referred to as a drill, which rotates them and provides torque and axial force to create the hole.

The shank is the part of the drill bit grasped by the chuck of a drill. The cutting edges of the drill bit are at one end, and the shank is at the other.

Drill bits come in standard sizes, described in the drill bit sizes article. A comprehensive drill bit and tap size chartlists metric and imperial sized drill bits alongside the required screw tap sizes.

Exceptionally, specially-shaped bits can cut holes of non-circular cross-section.

The term drill may refer to either a drilling machine or a drill bit for use in a drilling machine. In this article, for clarity, drill bit or bit is used throughout to refer to a bit for use in a drilling machine, and drill refers always to a drilling machine.

Many different materials are used for or on drill bits, depending on the required application. Many hard materials, such as carbides, are much more brittle than steel, and are far more subject to breaking, particularly if the drill is not held at a very constant angle to the workpiece; e.g., when hand-held.

Tungsten carbide and other carbides are extremely hard, and can drill virtually all materials while holding an edge longer than other bits. The material is expensive and much more brittle than steels; consequently they are mainly used for drill bit tips, small pieces of hard material fixed or brazed onto the tip of a bit made of less hard metal. However, it is becoming common in job shops to use solid carbide bits. In very small sizes it is difficult to fit carbide tips; in some industries, most notably PCB manufacturing, requiring many holes with diameters less than 1 mm, solid carbide bits are used.

Ferro Tungsten (FeW) Powder Description:

1) Ferro Tungsten is an alloy, which is formed by combining iron and tungsten with a tungsten content range in two grades (A and B) and the content ranges are 75%-82% and 70%-75% respectively.

2) Ferro Tungsten is a remarkably robust alloy because of its high melting point, tungsten has the second highest melting point after carbon. By combining iron with tungsten, the tendencies towards brittleness are overcome from the raw state of tungsten, and Ferro Tungsten is often a major component of popular super alloys.

Ferrotungsten Warming Time is Approaching

Today, domestic ferrotungsten mainstream market quotation is stable, mainly concentrated in the 123000-126000 Yuan/ ton; some contract prices are 120000 Yuan / ton. Shanghai is still high, with 128,000 Yuan / ton.

Recently, Tungsten market frequently burst the news of price increasing. And the upstream and downstream market prices try to increases, and received a good market response. Ferrotungsten manufactures feel calm of the depressed market. However, from the factory reflect the situation today, ferrotungsten market has gradually looking up.

Tips to Use Carbide Drill Bits

Carbide drill bits are typically made of tungsten carbide that is nickel based with a carbon coating. This type of drill bit has many applications, such as drilling into stone, metal and removing screws that will not come out of metal. Standard drill bits are not that strong and are made of a lesser quality material that can bend or break when drilling into hard materials. You can use a carbide drill bit by first finding a drill bit to use with your current drill.

Instructions
 
1.    Choose the type of carbide drill bit that is needed for the project or application. Carbide drill bits come in many varieties, such as a standard twist bit or a hole saw.
 
2.    Open the drill chuck by turning it counter-clockwise. The chuck is the hard rubber end at the tip of the drill.
 
3.    Insert the drill bit into the chuck.
 
4.    Tighten the chuck by turning it clockwise. Once the chuck has been hand-tightened, hold on to the chuck with one hand and then press the trigger once to activate the drill. This will ensure that the chuck is tightened properly to secure the drill bit.
 
5.    Place the drill with the carbide drill bit against the surface that you need to drill. Hold the drill at a 90 degree angle or perpendicular to the work surface.
 
6.    Press the trigger on the drill and lightly apply pressure to allow the bit to dig into the material.
 
7.    Spray water on the drill to dissipate the heat that is created from the drill bit drilling through the metal or stone.
 
Tips & Warnings
 
•     Carbide drill bits stay sharp longer than other types of drill bits.
 
•     Improper drilling can damage or break the carbide drill bit.

Europe Ferro Tungsten Market

Europe ferro tungsten market remains weak, Rotterdam warehouse transaction price falls.

By July, Europe ferro tungsten market still remains weak, spot market is disordered, Rotterdam warehouse transaction price is between 41.5 and 43 usd/kg-w, 41.5 usd/kg-w is clearing shipments price. The European steel mills implement reduction of output and overhaul in summer, market ferro tungsten purchase is reducing, bidding is also reducing, traders compete fiercely, MB oversea ferro tungsten quotation lasts by July, newest quotation is Rotterdam 41.5-42 usd/kg-w, however China ferro tungsten export price keeps stable, Basic maintenance in Rotterdam 41 usd/kg-w. Along with the market remains weak, less deals, parts of Europe traders are cutting price to promote transaction, related market participants think European ferro tungsten price still has a falling risk.

Although Russian Few70 market requirment remains weak,transactions are less. Limited by production costs, manufacturer is lack of adjusting price power, Few70's tax included price is steady at 1100-1250 rouble/kg(44.7-50.8 usd/kg-w), without obvious change. At present most of plants produce ferro tungsten depending on market requirment, as receiving few order in recent two month , some plants consider to stop manufacturing, most of plants compress production scale, some reduce 50%, plants quotation is stable, traders wait and see the future market.

Ferro-Tungsten & Melting Base

Ferro-Tungsten 

Ferro-tungsten is a master alloy for the production of tungsten-containing steels.  The raw materials for ferro-tungsten production are rich ore or ore concentrates of wolframite or scheelite.  Also artificial scheelite or soft scrap can be used.  The tungsten trioxide in these compounds can be reduced either carbothermically in electric arc furnaces or metallothermically by silicon and/or aluminum.  Also a mixed carbothermic-silicothermic production is in use.

Commercial ferro-tungsten contains between 75 and 85% W.  It has a steel grey appearance and a fine-grained structure consisting of FeW and Fe2W.  It is supplied in 80–100 mm lumps.

Melting Base

Melting Base is another master alloy in tungsten steel production. It can have various compositions according to the tungsten scrap material in use. The tungsten content varies depending on type between 10 and 38% besides iron and sometimes 5.5% Mo and also 5 to 10% Co.

Different types of scrap materials are mixed to meet the required composition. Reductive melting is done in electric arc furnaces and the melt is finally granulated by casting on a rotating disc and quenching in water (size <10 mm).

Tungsten Carbide Nozzle Microwave Sintering Technology

Tungsten carbide nozzle microwave sintering technology is a new sintering process, which has high heating speed, high energy efficiency, high heating efficiency and low pollution and other characteristics. It takes advantage of the special band of microwave and the material a basic fine structure to coupling for creating the heat so that the loss of dielectric material is heated to the sintering temperature of the material as a whole achieved good density of the material.

In the late 1980s, microwave sintering technology has been introduced in the field of materials science, and gradually developed into a new type of powder metallurgy rapid sintering technology. Its basic principle is different from conventional thermal heating process, which to the heating element reaches a certain temperature by convection, conduction or radiation. For traditional sintering, the material accepts the heat from outside so that it needs a long time for sintering and the grains will be growing up.
