General Cutting Tools
◎ As the tools have sharp cutting edges, you may cut your hands if they come into direct contact with the edges. ◎ Incorrect use or inappropriate application conditions could result in injuries caused by tool breakage or projectiles. ◎ If there is a sharp increase in cutting force due to high impact loads or excessive wear, injuries may result from tool breakage or projectiles. ◎ High temperature chips or lengthy chips being discharged may cause injuries or burns. ◎ Both the tool and work material will heat up during machining. Burns may occur if touched with bare hands immediately after machining operations. ◎ Chips may ignite or catch fire from sparks during machining or from heat produced from breakage. ◎ At high rotational speeds, injuries may result from tool breakage if the cutter (including the machine tool jig) is not balanced or if there is runout vibration. ◎ Burrs formed on workpieces are sharp and may cause injuries. ◎ If inserts or holder parts are not clamped properly, they may drop off or be flung out during machining. ◎ Using pipes to aid tightening may cause insert or tool breakage as a result of over tightening. ◎ The use of tools at high speeds is dangerous, as inserts may be flung out due to centrifugal force. Take extra care when handling very small drills. ◎ As the cutters have sharp cutting edges, you may cut your hands if they come into direct contact with the edges. ◎ Injuries may result from tool breakage or projectiles if there is rotational imbalance in the cutter, which causes wobbling or vibrations. ◎ When using rotary tools to perform through hole drilling, disc-shaped chips may be flung out at high speeds. Be careful, as the disc has extremely sharp edges. ◎ Drills with very small diameters have sharp tips and will prick the fingers. Surgery will be required if the drills break inside the finger. Drills may also scatter when fractured. Drills may also scatter shards when fractured. ◎ Injuries may result from a dislodged insert or from tool breakage. ◎ Tools that have been repeatedly brazed run a risk of breaking easily while in use. ◎ There is a danger of breakages and even injuries if machines and tools are used for applications other than their intended uses.
* Please use gloves and other protective gear, especially when removing a product from its case or mounting it onto a machine. * Use safety covers, safety glasses and other protection measures. * Always operate within recommended conditions. Please refer to the instruction manuals or catalogues. * Use safety covers, safety glasses and other protection measures. * Replace the tools before the indicated product lifetimes expire. * Use safety covers, safety glasses and other protection measures. * When clearing chips, please wear safety gloves and use an appropriate tool. * Use gloves and other protective measures, especially when removing products from their cases. * Please do not use this product in places where there are highly flammable or highly explosive materials. * If non-water-soluble coolant is used, precautions against fire must be taken beforehand. * Use safety covers, safety glasses and other protection measures. * Please perform a dry run to ensure that there is no vibration or abnormal noises.
* Do not handle with bare hands.
General Indexable Insert Tools
* Remove any foreign particles and clean all contact and clamping parts before mounting the inserts. * Check that inserts and parts have been properly clamped for mounting. Use wrenches provided for securing. Do not use inserts or parts not specified by the manufacturer. * Do not use tightening aids such as pipes, etc. Use the included wrench. * Always operate within recommended conditions. Please refer to the instruction manuals or catalogues. * Please use gloves and other protective measures, especially when removing products from their cases. * Rotational speeds should be kept within recommended conditions. * Regular maintenance should be performed to maintain the rotational balance and accuracy of the machine's spindle bearings. Worn bearings will lead to rotational imbalance and runout. * Use safety covers, safety glasses and other protection measures. A cover must also be mounted on the chuck. * Take extra care when handling very small drills. Use gloves and other protective gear such as safety glasses. * Please ensure that tools have been properly brazed before use. * Please do not use the product under high-temperature conditions. * Do not use tools that have been brazed repeatedly, as their strength will be lowered. * Always conform to the regulations specified for intended use.
