MultiDrill Series MDM Type (Internal Coolant Supply)

Recommended Cutting Conditions

1. The recommended cutting conditions below are for cases where an internal supply of a water soluble coolant is used. 2. If using non-water soluble coolant, reduce the cutting speed by 20-30% and ensure that sufcient coolant is supplied. 3. When mounting the drill in the collet, make sure that runout around the cutting edge is no greater than 0.02mm . 4. Make sure the ute does not enter the collet. 5. If the part entering the workpiece is abnormally shaped ( tilted, interrupted etc.), reduce the feed rate to about half when inserting the drill in the workpiece.

*If stable machining is still not possible, pre-machining of the at surface with the MDF Flat MultiDrill is recommended. 6. When performing intermittent through drilling, reduce the feed rate to about half the feed rate used prior to this process.
