Definition of carbide burrs.   Cemented carbide rotary burrs are made of carbide (WC, TiC) micron powder with high hardness and refractory metal as the main component, cobalt (Co) or nickel (Ni) or molybdenum (Mo) as the binder, powder metallurgy products sintered in a vacuum or hydrogen recovery furnace. IV B, V B, VI B group of metal carbide, nitride, boride, etc., because the hardness and melting point are particularly high, collectively known as cemented carbide.   To teach you the principles of choice   Selection of section shape of cemented carbide rotary burrs The section shape of cemented carbide rotary burrs should be selected according to the shape of the part to be rasped so that the two shapes are suitable. When filing inside the arc surface, choose the half-round file or round file (small diameter workpiece). When filing inside the angled surface, choose the triangle file. When filing inside right angle surface, choose a flat-file or square file, etc. When using a flat file to cut the right-angle surface, care should be taken to make the narrow surface (smooth edge) without teeth near the right-angle surface, so as to avoid hitting the right-angle surface.        

Cemented carbide’s comprehensive properties   Cemented carbides are usually composed of ultrafine powders of WC and TiC with high hardness and refractory metal, using cobalt (Co) or nickel (Ni) or molybdenum (Mo) as binder, powder metallurgy products sintered in a vacuum or hydrogen reduction furnace. Cemented carbide is known as “industrial tooth”, mainly used in cutting tools, stamping tools, molds, mining and construction, road engineering machinery, and other fields. Cemented carbide production process   Classification of cemented carbides Cemented carbides are usually classified according to their field of application and tungsten carbide grain size. According to the application field, it can be divided into mining tool alloy, cutting tool alloy, and wear-resistant tool alloy. And according to the grain size, it can be divided into seven different categories, such as nano-crystal and ultra-fine crystal. Generally speaking, the smaller the grain size, the higher the hardness and the better the wear resistance, but at the same time, the toughness decreases and the impact resistance is poor. Therefore, nanocrystalline, ultra-fine-grain, and sub-fine grain cemented carbides are widely used in cutting tools because of their high hardness, wear-resistance, and sharp cutting edge. Fine and medium grain cemented carbides are mainly used in cutting

What is a Die Grinder? A die grinder is a tool that features a rotating spindle and a collet for holding the cutting bit. Die grinders could be a portable and handheld tool or a fixed-to-the-bench type. This power tool uses attachments such as drill/grinding bits, which rotate at a very high speed. They are useful for the removal of objects from the work-piece. They appear similar to rotary tools and are powered using either electricity or compressed air. When you use die grinders with the right attachment, they are capable of performing various tasks. Although die grinders are used on metals for tool and die making, they can be used on other materials such as plastic and wood. They come in a variety of sizes and can be either straight or angled. Types of Die Grinder Pneumatic Grinders The most common type of die grinders is powered by compressed air and is referred to as Pneumatic Grinders. They use a large amount of air; however, a small 20-gallon compressor can fuel them for a long period. The speed of a pneumatic grinder can be controlled using the throttle on the handle. Pneumatic grinders are reasonably priced and are very

Not all burrs are the same. The material composition of the burr can go a long way in the results they bring, what they are used to work on and their usage.  In this post, we will be talking about the differences between Ceramic burr and carbide burrs. So, what are the differences between carbide burrs and ceramic burrs? And what are the advantages/ disadvantages of using one over the other? Are there any? Let’s find out. What is a Ceramic Burr? Ceramic burrs like the name implies are burrs made from ceramic. They are durable like other ceramic tools that we have. Ceramic burrs are great for blends and espresso as they provide that “traditional espresso flavour profile.” What is a Carbide Burr? Carbide burs are made from tungsten carbide. They are used for cutting, grinding, and shaping material with which they work. They are also used in deburring materials, sharp edges, as well as remove weld beads. Carbide burrs are versatile with usage in jewellery work, welding, metalworking, woodworking and stone working. What do I Use Ceramic and Carbide Burrs for? Ceramic burrs are to remove dentin and cavity preparation. A Ceramic burr is a safe tool that
