Solid Carbide Drills for Stainless Steel and Exotic Alloys
MultiDrill Series MDM Type
■ General Features ● Newly developed oil hole shape with excellent cooling performance achieves longer tool life. ● Effective cooling of the cutting edge created through fluid analysis. Reduces adhesion breakage. ● Chip control and work hardening problems resolved, all in one. ● Outstanding stability in machining of stainless steel and exotic alloys.
J
■ Features and Applications ● Greater discharge of coolant for effective cooling of the cutting edge.
*Suitable for drill diameters of ø4.1 or larger
Newly developed bean-shaped oil hole supplies coolant on cutting edge for effective cooling of the cutting edge
MDM Type
Discharge 2 x or more
Conventional Tool
The secret is in the concave areas!
● New technology created through fluid analysis for effective cooling of the cutting edge

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 sufficient 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 flute 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 flat 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.
