3. Four margins and a self-centering drill geometry enables high hole precision and quality

Drill bodies & Grades

Standard cutting conditions

ISO	Workpiece material	Brinell hardness (HB)	Cutting speed Vc (m/min)	Feed: f (mm/rev)
				ø6 – ø9.9	ø10 – ø16
	Grey cast irons FC300, etc. 250, etc.	– 200	60 – 120	0.2 – 0.8	0.3 -1.0
	Ductile cast irons FCD450, etc. 450-10S, etc.	– 300	60 – 120	0.2 – 0.8	0.3 -1.0

• The cutting parameters shown in the table are a starting guideline.
  Values should be varied depending on the power or rigidity of the machine.
  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 values.
• When drilling with a depth deeper than L/D = 3, a pecking cycle or dwell operation should be considered depending on the actual chip control.
