1. The Jndlcated speeds and feeds are for drilling wlth water-soluble oll. When uslng non-water soluble oll, set the drUUng speed, reduce the dnlNng speed by 20-30%.

2.The most sultable cuttlng fluld is water-soluble oll (10-30 times dilution).

3.Refer to the "Coolant Application Key Points" for instructions on how to apply the coolant.

4.If chip evacuation becomes difficult during non-step drilling due to the type of work material or its annealed condition, perform step-feed drilling. In this case, we recommend the peck feed method in which the drill is retracted at a rate of approximately 100 times the feed rate (mm/rev).

5.If the number of nozzles on a horizontal machine center is too few

insufficient, perform step-feed drilling. In this case, we recommend a

or the discharge flow rate is step-feed method in which the

drill is retracted to the entrance of the hole. 6.Be sure to center the hole before using this drill. To center the hole, use an OSG leading drill (NC-LDS,

VP-LDS, etc.) or a stub drill of the same diameter to make a pilot hole.

The point angle of a leading drill may be 90° 120° or 130° 7. Use the step-feed method for drilling in quenched and tempered steels.
