SUGGESTIONS ON HOW TO USE CUTTING TOOLS

Products	Hazard	Countermeasure
All Cutting Tools	Cutting tools have sharp cutting edges Handling them with bare hands may cause injuries.	*Take precautions such as wearing gloves especially when handling tools and during installation.
	Improper use of tools and application of inappropriate cutting conditions may cause the tool to break and be expelled from the machine providing risk of injury.	*Ensure safety guards and goggles are used. *Refer to handling explanatory notes and catalogues.  Use tools under recommended cutting conditions.
	Impact load and rapid increase of cutting resistance due to excessive wear may cause the tool to break and be expelled from the machine providing risk of injury.	*Ensure safety guards and goggles are used. *Exchange tools before excessive wear occurs.
	Cutting tools and workpieces become extremely hot during cutting. Touching them with bare hands may cause burns.	*Take precautions such as wearing gloves.
	Expelled hot chips produced in cutting produces risk of injuries and burns.	*Ensure safety guards and goggles are used. *During swarf removal and machine cleaning ensure the machine is stopped and wear gloves.
	In cutting, sparks, hot chips and heat generation caused by tool breakage provides a risk of igniting a fire.	*Avoid using cutting tools in places where there is a possibility of igniting a fire. *In case of using non-water soluble oil, make sure to have a fire prevention countermeasure.
	Using machines, chucks, and tools with poor balance at high revolutions may cause tools to break providing risk of injuries.	*Ensure safety guards and goggles are used. *Check the machine for vibration, chattering, and abnormal noise.
	Handling machined parts with burrs using bare hands may cause injuries.	*Wear gloves.
Indexable Inserts	If inserts and spare parts are not held securely, they may become loose and be expelled producing risk of injuries.	*Clean insert locating seat and spare parts before setting inserts. *Use the tool provided for setting inserts, and ensure the inserts and spare parts are clamped securely. *Do not use the tool provided for things other than prescribed inserts and spare parts.
	Clamping inserts and spare parts too tightly by using tools such as extension pipes may cause them to break and be expelled.	*Do not use extra tools for more leverage. Only use the tool provided.
	When applying high cutting speed, spare parts and inserts may be expelled due to centrifugal force.	*Refer to the handling explanatory notes and catalogues. Use tools under recommended cutting conditions.
Cutters and Other Rotating Tools	Milling cutters have sharp edges. Handling them with bare hands may cause injuries.	*Take precautions such as wearing gloves.
	Poor balance or off centre revolving of tools may cause vibration and chattering which could cause the tool to break and be expelled.	*Apply cutting speed within the range of recommended cutting conditions. *Adjust accuracy and balance of spindles and bearings periodically to prevent off centre revolving and chattering caused by wear on these parts.
Drills	Through cutting in cases when the workpiece revolves may produce a disk shaped peice with sharp edges when the cutting tool breaks through.	*Ensure safety guards and goggles are used.
	Drills with an extremely small diameter have a very sharp point which may puncture the skin if not handled carefully. If the drill breaks during cutting, the broken pieces may be expelled.	*Handle with care. Take precautions such as wearing gloves and goggles.
Brazed Tools	Weakening of the braze and breakage of inserts may cause injury.	*Before using them, ensure they are brazed securely. *Do not use them under conditions which produce very high temperature.
Others	Machine and tools may be damaged if they are used for purposes other than the prescribed application.	*Use them strictly for the prescribed application.
