Standard cutting conditions Cautionary points in use
• When drilling steel, a water soluble cutting fluid should be used.
Work materials Cutting speed: Vc (m/min) Feed: f (mm/rev)
Carbon steels • Fluid pressure of 1 MPa or higher and fluid quantity of 10R /min or more are essential.
60-65-70 0.07-0.12-0.17 • For tool-rotating applications, use a commercially available rotary coolant supply holder.
Alloy steels (However, TDP60-65 and TDP65-70 must be used only for work rotating applications
Cast irons 70-80-100 0.1-0.15-0.2 because their shank diameters are as large as ø50 mm.)
Note: For drills with diameter less than 37 mm, reduce the feed • Drilling into stacked plates tends to damage the tool and is not recommended.
to less than 0.13 mm/rev (0.15 mm/rev for cast irons). • Not suitable for low carbon steels (SS400) and stainless steels (SUS304).
• No. of revolutions (min -1 ) = Cutting speed10003.14Tool diameter  : Stocked items.
• Table feed (mm/min) = No. of revolutionsFeed per revolution  : Stocked in Japan
