High Speed Tools Steel is an important Tools materials,mainly for making cutting tools and cold-working mould. A、 Mainly used for making cutting tools It has following priority comparing to Solid Carbide materials Cutting tools,which is another main materials for Cutting tools： 1.It's manufacturing process simple and convenient to be manufactured by machine.Its very profitable for making complex cutters.The user could re-forge HSS materials and change its sizes and shape in necessory. 2.Convenient to grind the very sharp cutting edge without use of expensive super hard abrasive materials-CBN GRINDING WHEEL . 3.HSS with better Hardness and grandability after heat treatment.Its HRC ranging from 61-70 per different code.And it still can keep higher Heat Hardness in temperature not over 5600C. 4.After heat treatment,the HSS Tool steel's presure resistance and Impact Toughness far better than Solid Carbide Tools. And also cause of its better presure resistance,they are suitable for interrupted cuttings and impact load tools. 5.It also can be used for 30m/Min high speed cutting.The HSS Tools Steel gear cutter hob,the rolling speed could reach 100m/Min in suitable method. B、 For making Cold-working Die materials. It has following advantages comparing to general Cold-working mould steel. 6. Good and Better Grandability, prolong the mould usage life. 7.Higher Pressure Resistance which make it hard to change mould sizes in high pressure when working.

PLEASE REMEMBER1. When using electric tools, machines or equipment, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury.2. Keep work area clean. Cluttered areas invite injuries3. Consider work area conditions. Don’t use machines or power tools in damp, wet or poorly lit locations. Don’t expose equipment to rain, keep work area well lit. Don’t use tools in the presence of flammable gases or liquids.4. Keep children away, all children should be kept away from the work area.5. Guard against electric shock. Prevent bodily contact with grounded surfaces such as pipes, radiators, ranges, and refrigerator enclosures.6. Stay alert. Never operate if you are tired.7. Don’t operate the product if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgment or reaction might be impaired.8. Don’t wear loose clothing or jewelry as they can be caught in moving parts.9. Wear restrictive hair covering to contain long hair. Use eye and ear protection.10. Keep proper footing and balance at all times.11. Don’t reach over or across running machines. Before operating1. Be sure the switch is OFF when not in use and before plugging in.2. Don’t attempt to use inappropriate attachments in an attempt to exceed the tools capacity. Approved accessories are available from the dealer or machine maker.3. Check for damaged parts, before using any tool, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function.4. Check for alignment and binding of all moving parts, broken parts or mounting fixture and any other condition that may affect proper operation. Any part that is damaged should be entirely or replaced by a qualified technician.5. Do not use the tool if any switch does not turn off and on properly. MAIN APPLICATION AND CHARACTERISTICS1.

1. Main difference of end mills made of good tungsten carbide and common tungsten carbide (different material and the same manufacturing process)They have similar performance on hardness, toughness and the difference is on the wear resistance, which mostly decides the life of the end mill.End mills made of common tungsten carbide only apply for cast iron, carbon steel, low alloy steel, copper alloy. These materials have low tensile strength (under 1000Mpa) and low hardness (under 30HRC). For stainless steel, high alloy steel, prehardended steel, hardened steel (high hardness or high tensile strength), these end mills have inferior performance and even can't work on these materials. Usually the life of end mills made of tungsten carbide is about 30% shorter than that of end mills made of good tungsten carbide when milling low tensile strengh materials or low harden materials.2. Main difference of end mills made of CNC machine and common machine (the same tungsten carbide)They have the same performance on hardness, toughness and wear resistance and the difference is on the tolerance.Usually we have 3 types of tolerances on end mills, tolerance of shank and diameter, tolerance of flute and tolerance of cutting edge. They have the same tolerance of shank and cutting diameter. The main difference is on the tolerance of flute and the tolerance of cutting edge. For milling metals, the most importance is to make sure that the cutting edges of end mill can touch the work-piece at the same time, which need smaller tolerance of end mill. And, we can control the tolerance of cutting edge in 1S (0.01mm) by CNC machine. The common machine can control the tolerance of cutting edge in about 5S (0.05mm) if the workers are on good status. So, when milling metals, the end mills made by common machine shall have one edge or 2 edges touch the surface firstly and others touch the surface lately. As for end mills made by CNC, the four edges touch the surface at the same time, which can improve the life of end mill greatly. Usually the life of end mill made by CNC machine is 40% longer than that of end mill made by common machine. Anymore, the end mill made by common machine only apply for low speed cutting (under 30m/min).3. Usually, we use 3 brands of tungsten carbide to make solid carbide tools. They are K10, K20, K30 and sometimes, we also use other brands of tungsten carbide for special usage.
