• Drill depth should be under 0.5D. (D: Drilling Dia.)
 Use compressed air during drilling.

• PR660 is recommended for heavy drilling.

• Drilling conditions should be calculated as one ute line. Step feed (0.5-0.1mm) is recommended.                          : 1st Recommendation
• Coolant is recommended when drilling stainless steel / cast iron.
• PR660 is recommended for heavy drilling.
