How we can get long life in tools?

People always likes to get the tools with prolong life. Cutting tool's life can be based on the economical, tool geometry, performance. The economical conditions based on the cutting speed, feed and depth measures. The tool geometry is means to obtaining the optimum geometry by the tools. The performance of the tools is based on the tool material, cutting fluid, work material and machine tool.
Based on the tools type the life can be varied such ad drill and milling tools life is different from one another. Excessive feed pressure, poor cutting with sharp drills or drill breakages can indicate that the drill tip has an insufficient lip relief angle. Drilling machines with continuous speed change is better than stepped or periodical speed change. In milling tools, the shallow depth with high feed gives higher metal removal rate and increased life.
Here are some ideas for getting tools in long life,

Using lubrication
While using tools for larger diameter steel area, it produces the heat and damages the tools. For avoiding that use oil for, this lubricates the metal and tools as it spins. The oil also acts as a heat sink absorbing much of the heat. Simply squirt oil on the metal before you start to tools and add more oil as you operate.

Use coating
To increase the life of high-speed steel, tools are sometimes coated. One such coating is TiN (titanium nitride). Most coatings generally increase a tool's hardness and/or lubricity. A coating allows the cutting edge of a tool to cleanly pass through the material without having the material stick to it. The coating also helps to decrease the temperature associated with the cutting process and increase the life of the tool.

Using air circulation
Tools with the turning heads and turning type tools using the coolant bearings for avoiding the heat also gives long tool life. Usually the machine tools are having sealed bearing in the head but it will not help during overheat, while it also cause the problem. For avoiding this problem the bearing with air circulations can help to cool the tools and it increases the tools life.

Benefits of choosing tungsten carbide Drills


A drill is a type of cutting tools; commonly it is used for boring holes in the material in which the material is hard. Drills are used various applications such as woodworking, metalworking and construction other than it is used some personal work.
The tungsten carbide is the stuff that gives hardness to the drill tools compared to the other material; it gives less cost and more usability. Basic drill types in tungsten carbide are solid carbide drills, carbide indexable insert drills, carbide drill bits and welded crown replaceable tungsten carbide drill.

Solid carbide drills
The Solid carbide drills are different from other drills and it is practiced in the small spacing applications. With the help of solid carbide drill, can drill holes in a lot of surfaces such as stone and masonry. The carbide masonry drill bit can be 39 inches long and can dig through concrete to help install wiring and plumbing. Using the solid carbide drills gives superior strength, precise in cut and prolonged usage.

Carbide indexable insert drills
Insert drill is small tool and it provides cutting operations because they not brazed or welded to the instrument body. The main advantage of insert drills is less cost because the small part only made up of the carbide. The ability to employ replaceable inserts in a variety of grades and geometries also provides flexibility advantages.

Carbide drill bits
This carbide drill bits are moved over the benefit while drilling into heavy steel and other textiles such as rock. This also makes the precision in cutting and this comes in different in varieties such as hole saws and standard twist bits. Carbide drill bits can enhance performance when utilizing the drill, and make it easier to finish a building job or house repair task. Carbide drill bits are also commonly used in machine shops across the country and also it gives long durable life.

Welded crown replaceable tungsten carbide drill
This is the new generation of drilling tools and this is composed of steel and replaceable solid carbide drill body crown. It machining operation is precision compared to other drill due to the crown can be substituted. This drill adopts self-centering blade geometry, cutting force is small, for the majority of work piece material all can achieve good chip control, good surface finish, processing the hole size precision and positioning precision is very high, no longer for subsequent finishing. This support internal cooling method so it can be used in machining center, CNC lathe or other high speed machine tools.

When choosing carbide drill machining accuracy, first of all need to look at the size of the drilling machining accuracy requirement. In general, by processing the bore is smaller, the smaller tolerance also.
