SAFETY GUIDE OF CARBIDE PRODUCTS KORLOY Inc. is continuously trying to develop safer and higher quality products Please be aware of the safety guidelines below prior to using KORLOY Inc. products It is generally accepted that the proper handling of cemented carbide tools requires awareness of safety as noted above. For more information, please contact us. KORLOY does not accept any responsibility for any accident caused by inappropriate use, abuse of tools, or changes to the products. 1. PL (Product Liability) In accordance with the PL (Product Liability) law, we have attached a WARNING label on the case of KORLOY products. There is no warning on the surface of the tools. Please read this safety guidelines before using carbide tools and provide safety education to all users. 2. Basic characteristics of CEMENTED CARBIDE tools Cemented carbide tools are made of carbides, nitrides, carbonitrides, oxides of Tungsten(W), Titanium(Ti), Alluninyum(AI), Silicon(Si), Tantalum(Ta), Boron(B) etc and metal omponent like Cobalt(Co), Nickel(Ni), Chrom(Cr), Molybdenum(Mo) as binder. Cemented carbides tools have high hardness and specific gravity. Generally there's no smell but according to usage and treatment, appreance and color could be changed 3. Precaution for CEMENTED CARBIDE tools 1) Cemented carbides are extremely hard and brittle at the same time. Impact shock or excessive clamping power could cause fracture or breaking of the tool. 2) Cemented carbides have large sepcific gravity, thus they require special attention as a heavy material when you handle big sizes or large quantities. 3) Cemented carbides have different thermal expansion coefficient with steel and ferrous materials. Shrink fit or swell fit products may cause trouble if they are used at undesirable conditions like extremly high or low temperatures. 4) There are several cemented carbide products having sharp cutting edges. Be careful not to handle the tools with bare hands which may cause cuts or injury, especially when removing the tools from the case, do not touch the cutting edge and be careful not to drop it. 5) Storing carbide tools in a corrosive atmosphere may cause erosion which can reduce toughness. 6) Please refer to the catalouge safety guidance prior to handling the tools. 7) Do not absue tools under inappropriate conditions. 4. Precaution for machining (grinding, welding, EDM) of CEMENTED CARBIDE tools 1) Surface condition can affect the toughness of the tool, so it is recommended to use a diamond grinding wheel. 2) Grinding of cemented carbide creates mist and dust. It contains harmful compositions like Cobalt(Co), thus it is recommended to use a mask, mist collection, and other protective facilities. If the dust gets in your skin or eye, rinse immeditely with continously running water. 3) In case of grinding with coolant, coolant contains harmful metal components which cause environmental problems. Handle the coolant according to the manufacturer's recommendations. 4) Check for cracks after re-grinding carbide tool and reuse. 5) Marking with laser or electric pen may cause cracks on the carbide tool. The crack can shortened tool life. 6) EDM of carbide may cause residual cracks on the carbide tool, so if necessary remove the crack with a grinding process. 7) Brazing of carbide tools at extremly high or low temperatures compare with the melting point of brazing materials may cause loosening or breakage. 8) Overheating a oil base coolant may cause a fire or flames, thus be prepared for fire prevention.
