| Direct touch to a sharp cutting edge may cause injury. | When you set up tools to the machine or take tools out of the case, please wear protective gloves. |
| Misuse or inappropriate working conditions may cause tool breakage or dispersion of broken pieces. | • Please use safety items, such as safety glasses and protective gloves. • Please use in the range of our recommended cutting condition. See our catalog or instruction manuals. |
| Excessive impact or heavy wear will increase cutting force and may cause tool breakage and dispersion of broken pieces. | • Please use safety items, such as safety glasses and protective gloves. • Early exchanging tools is prefereable. |
| General | Dispersion of heated or prolonged chips may cause injury or burn. | • Please use safety items, such as safety glasses and protective gloves. • For chips removal, please stop the machine beforehand and use safety items, such as safety glasses and protective gloves. |
| cutting tools | Tools and materials reach high temperatures during cutting operation. Direct touch to the tools and materials shortly after cutting may cause burn. | Please prepare safety items, such as safety glasses and protective gloves. |
| Sparks, generation of heat or chips in high temperature during operation may cause fire. | • Please do not operate around Hazardous zone, in which there is some pos- sibility of fire or explosion. • In case of using oil-coolant, please make sure there is sufficient fire-protection equipment. |
| Lack of dynamic balance during high-speed revolutions leads to vibrations which can make the tool break. | • Please use safety items, such as safety glasses and protective gloves. • Please conduct test-operation before cutting, and confirm that there is no vibration or unusual sound. |
| Direct touch to burrs which were generated on the rough surface of the workpiece may cause injury. | Do not touch workpiece with bare hand. |
| If the inserts or other tool parts are not installed properly, they can fall down or break which may cause injuries. | • Please clean up insert pockets or clamping parts before setting insert. • Please set up inserts with supplied wrench only, and confirm that the inserts or parts are clamped completely. Never use inserts or parts other than those prescribed. |
| Indexable cutting tools | If inserts are clamped too tightly by supplementary tools like pipe etc, inserts or body may brake. | Do not use aids such as pipes. Please set up using supplied wrench only. |
| When tools are used in high-speed revolution, inserts or parts may burst out of the body due to centrifugal force. When handling, please pay special at- tention to safety. | Please use in the range of our recommended cutting conditions. See our catalog or instruction manuals. |
| Milling cutters and | Since milling cutters have sharp edges, direct contact with bare hands may cause injury. | Please use safety items, such as safety glasses and protective gloves. |
| other milling tools | If a cutter lacks balance, the tool can start to vibrate. The dispersion of broken pieces can cause injuries. | • Please use in the range of our recommended cutting condition. • Accuracy and balance of machine spindle should be checked and adjusted regularly to prevent wear of the bearings due to eccentric rotation. |
| Drilling | When drilling a through-bore, it is possible that a disc is created during the drilling procedure that can fly out of the workpiece at a high speed. This is very dangerous since the disc has sharp edges. | Please use safety items, such as safety glasses and protective gloves. Also attach a cover on a chuck part. |
| Brazed tools | Dispersion or falling down of broken inserts may cause injury. | • Please check that the cutting inserts are brazed firmly before use. • Please do not use brazed tools in the condition that requires high cutting temperature. |
| If brazing is carried out many times, the strength of carbide insert is deteriorated and can break easily during cutting. | Please do not use tools that have been brazed several times. The quality of the tool deteriorates. |
| Others | The tools can only be used for the appropriate application. It may damage tools and machines. | Please follow our recommended usage for the tools. |
