Introduction Precaution for using cutting tools Target products Precariousness Countermeasures 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 ordispersion 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 • Please use safety items, such as safety glasses and protective gloves. tool breakage and dispersion of broken pieces. • Early exchanging tools is prefereable. • Please use safety items, such as safety glasses and protective gloves. Dispersion of heated or prolonged chips may cause injury or burn. • For chips removal, please stop the machine beforehand and use safety items, such as safety glasses and protective gloves. General 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. • Please do not operate around Hazardous zone, in which there is some pos- Sparks, generation of heat or chips in high temperature during sibility of fire or explosion. operation may cause fire. • In case of using oil-coolant, please make sure there is sufficient fire-protection equipment. Lack of dynamic balance during high-speed revolutions leads tovibrations 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 thereis no vibration or unusual sound. Direct touch to burrs which were generated on the rough surface of theworkpiece may cause injury.Do not touch workpiece with bare hand. • Please clean up insert pockets or clamping parts before setting insert. If the inserts or other tool parts are not installed properly, they can fall down • Please set up inserts with supplied wrench only, and confirm that the or break which may cause injuries. 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 outof 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. Since milling cutters have sharp edges, direct contact with bare hands maycause injury.Please use safety items, such as safety glasses and protective gloves. Milling cutters and other milling tools If a cutter lacks balance, the tool can start to vibrate. The dispersion ofbroken pieces can cause injuries.• Please use in the range of our recommended cutting condition.• Accuracy and balance of machine spindle should be checked and adjustedregularly 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 thedrilling procedure that can fly out of the workpiece at a high speed. This isvery 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. • Please check that the cutting inserts are brazed firmly before use. Brazed tools Dispersion or falling down of broken inserts may cause injury. • 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 Please do not use tools that have been brazed several times. and can break easily during cutting. The quality of the tool deteriorates. Others The tools can only be used for the appropriate application. It may damage tools Please follow our recommended usage for the tools. and machines. 3
