Precaution for using cutting tools

Target productsPrecariousnessCountermeasures
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.
GeneralDispersion 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 toolsTools 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 toolsIf 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 andSince 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 toolsIf 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.
DrillingWhen 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 toolsDispersion 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.
OthersThe tools can only be used for the appropriate application. It may damage tools and machines.Please follow our recommended usage for the tools.
