• The cutting parameters shown in the table are merely a starting guideline for general machining. Values should be varied depending on the power or rigidity of the machine to be used. Optimum conditions should be selected depending on the actual chip control or damage on edges.
• When using the smaller diameter tools in each range, set the feed “f” to the lower recommended values.
• The coolant supply is critical for the provision of stable machining conditions and enhanced tool life. A large coolant volume should be supplied, especially when drilling di! cult-to-cut materials.
• When drilling stainless steel with low machinability such as austenitic stainless steel with a depth deeper than L/D = 3, a pecking cycle or internal coolant supply is recommended.

• The cutting parameters shown in the table are merely a starting guideline for general machining. Values should be varied depending on the power or rigidity of the machine to be used. Optimum conditions should be selected depending on the actual chip control or damage on edges.
• When using the smaller diameter tools in each range, set the feed “f” to the lower recommended values.
• Oil holes that become blocked may cause drill breakages. A fi lter to prevent the circulation of chips must be used on the coolant supply system.

• When the drilling depth is deeper than L/D = 5, use drill pecking every 10 to 50% of the drill diameter.
• The above cutting conditions are applied to when a water soluble cutting fluid is used. For drilling a hole smaller than ø0. 3 mm, use of a starting drill is recommended.
• When setting the drill, the drill runout should be within 0.002 mm on the taper. (Especially for the drill diameter smaller than ø0.5 mm)
