Attentions on Safety
2. Cautions regarding mounting(1) Before use, check the outside appearance of the tool for scratches, cracks, etc. and that it is firmly mounted in the collet chuck, etc.(2) If abnormal chattering, etc. occurs during use, stop the machine immediately and remove the cause of the chattering.
4. Cautions regarding regrinding(1) If regrinding is not performed at the proper time, there is a risk of the tool breaking. Replace the tool with one in good condition, or perform regrinding.(2) Grinding dust will be created when regrinding a tool. When regrinding, be sure to attach a safety cover over the work area and wear safety clothes such as safety
goggles, etc.(3) This product contains the specified chemical substance cobalt and its inorganic compounds. When performing regrinding or similar processing, be sure to handle the
processing in accordance with thelocal laws and regulations regarding prevention of hazards due to specified chemical substances.
1. Cautions regarding handling(1) When removing the tool from its case (packaging), be careful that the tool does not pop out or is dropped. Be particularly careful regarding contact with the tool flutes. (2) When handling tools with sharp cutting flutes, be careful not to touch the cutting flutes directly with your bare hands.
3. Cautions during use(1) Before use, confirm the dimensions and direction of rotation of the tool and milling work material.(2) The numerical values in the standard cutting conditions table should be used as criteria when starting new work. The cutting conditions should be adjusted as
appropriate when the cutting depth is large, the rigidity of the machine being used is low, or according to the conditions of the work material.(3) Cutting tools are made of a hard material. During use, they may break and fly off. In addition, cutting chips may also fly off. Since there is a danger of injury to
workers, fire, or eye damage from such flying pieces, a safety cover should be attached when work is performed and safety equipment such as safety goggles should be worn to create a safe environment for work.
(4) There is a risk of fire or inflammation due to sparks, heat due to breakage, and cutting chips. Do not use where there is a risk of fire or explosion. Please caution of fire while using oil base coolant, fire prevention is necessary.
(5) Do not use the tool for any purpose other than that for which it is intended.

【Selection of cutting conditions】* These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. * Please select the cutting conditions with a feed rate of 1% of the tool diameter as a general criteria.* These cutting conditions are based on using water-soluble cutting lubricant (diluted 10 to 20 times).* When mounting a tool, use a collet without scratches or stains.* Adjust the conditions as necessary according to the workpiece storage conditions and machine conditions.* If the maximum revolution rate of the machine being used does not reach the rate stated in the standard cutting conditions, use the machine at its maximum revolution rate.

【Note】1. Use the appropriate coolant for the work material and machining shape.2. These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. 3. If the rpm of the machine is low, lower the feed rate also to put the rpm and feed rate in the same ratio.4. Please use slotting only. This is not recommended for side milling.

【Selection of cutting conditions】* These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. * Please select the cutting conditions with a feed rate of 1% of the tool diameter as a general criteria.* These cutting conditions are based on using water-soluble cutting lubricant (diluted 10 to 20 times).* When mounting a tool, use a collet without scratches or stains.* Adjust the conditions as necessary according to the workpiece storage conditions and machine conditions.* If the maximum revolution rate of the machine being used does not reach the rate stated in the standard cutting conditions, use the machine at its maximum revolution rate.

Epoch Deep Square Recommended cutting conditions EPDS EPDS-TH
1. Use the appropriate coolant for the work material and machining shape.2. These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. 3. If the rpm of the machine is low, lower the feed rate also to put the rpm and feed rate in the same ratio.
※Standard cutting depth is shown as the criteria for Group 2 workpieces. For other groups, adjust the cutting depth according to the cutting depth factors in the above table.

※For details about the CS series, refer to work groups 1 - 4. For details about the TH series, refer to work groups 4 - 6.
※(1) Standard cutting depth is shown as the criteria for Group 2 workpieces. For other groups, adjust the cutting depth according to the cutting depth factors in the above table.※(2) When performing cutting where cutting chips may cause clogging, such as for rib processing, blind grooves, etc., cutting depth setting should be set by multiplying a cutting depth factor to calculate the cutting depth amount, and this amount should then be reduced to 80% of the calculated value.
Cutting depth setting example: When cutting rib groove contours in quenched steel (50HRC) using an EPDB2006-1-TH tool:Cutting depth = 0.05 (standard cutting depth) × 0.65 (cutting depth factor for Group 4 quenched steel) × 0.8 (for closed-area cutting) = 0.026mm

Epoch Deep Ball Recommended cutting conditions EPDB EPDB-TH
① Use the appropriate coolant for the work material and machining shape.② These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. ③ If the rpm of the machine is low, lower the feed rate also to put the rpm and feed rate in the same ratio.

※For details about the CS series, refer to work groups 1 - 4. For details about the TH series, refer to work groups 4 - 6.
※(1) Standard cutting depth is shown as the criteria for Group 2 workpieces. For other groups, adjust the cutting depth according to the cutting depth factors in the above table.※(2) When performing cutting where cutting chips may cause clogging, such as for rib processing, blind grooves, etc., cutting depth setting should be set by multiplying a cutting depth factor to calculate the cutting depth amount, and this amount should then be reduced to 80% of the calculated value.
Cutting depth setting example: When cutting rib groove contours in quenched steel (50HRC) using an EPDB2006-1-TH tool:Cutting depth = 0.05 (standard cutting depth) × 0.65 (cutting depth factor for Group 4 quenched steel) × 0.8 (for closed-area cutting) = 0.026mm

Cutting depth setting example: When cutting rib groove contours in quenched steel (50HRC) using an EPDBP2006-2-04-TH tool:Cutting depth = 0.055 (standard cutting depth) × 0.65 (cutting depth factor for Group 4 quenched steel) × 0.8 (for closed-area cutting) = 0.028mm

① Use the appropriate coolant for the work material and machining shape.② These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type. ③ If the rpm of the machine is low, lower the feed rate also to put the rpm and feed rate in the same ratio.

Attentions on Safety
2. Cautions regarding mounting(1) Before use, check the outside appearance of the tool for scratches, cracks, etc. and that it is firmly mounted in the collet chuck, etc.(2) If abnormal chattering, etc. occurs during use, stop the machine immediately and remove the cause of the chattering.
4. Cautions regarding regrinding(1) If regrinding is not performed at the proper time, there is a risk of the tool breaking. Replace the tool with one in good condition, or perform regrinding.(2) Grinding dust will be created when regrinding a tool. When regrinding, be sure to attach a safety cover over the work area and wear safety clothes such as safety
goggles, etc.(3) This product contains the specified chemical substance cobalt and its inorganic compounds. When performing regrinding or similar processing, be sure to handle the
processing in accordance with thelocal laws and regulations regarding prevention of hazards due to specified chemical substances.
1. Cautions regarding handling(1) When removing the tool from its case (packaging), be careful that the tool does not pop out or is dropped. Be particularly careful regarding contact with the tool flutes. (2) When handling tools with sharp cutting flutes, be careful not to touch the cutting flutes directly with your bare hands.
3. Cautions during use(1) Before use, confirm the dimensions and direction of rotation of the tool and milling work material.(2) The numerical values in the standard cutting conditions table should be used as criteria when starting new work. The cutting conditions should be adjusted as
appropriate when the cutting depth is large, the rigidity of the machine being used is low, or according to the conditions of the work material.(3) Cutting tools are made of a hard material. During use, they may break and fly off. In addition, cutting chips may also fly off. Since there is a danger of injury to
workers, fire, or eye damage from such flying pieces, a safety cover should be attached when work is performed and safety equipment such as safety goggles should be worn to create a safe environment for work.
(4) There is a risk of fire or inflammation due to sparks, heat due to breakage, and cutting chips. Do not use where there is a risk of fire or explosion. Please caution of fire while using oil base coolant, fire prevention is necessary.
(5) Do not use the tool for any purpose other than that for which it is intended.
