Optimal design chip pocket.
Wide and deep chip pocket minimize the friction during operation.
Curvilinear edge.
Since curvilinear edge decrease cutting force by dispersing cutting load, excellent wear resistance and shock resistance acquired.
Ultra micro grain substrate and New TiAlN coating.
0.6 of tungsten carbide has been used for carbide substrate.
New TiAlN coating film guarantees excellent shock resistance & wear resistance.
Standard aspect ratio 3D, 5D, 7D
For example, diameter 10mm, and depth of drill 30mm, no through coolant drill, take MSD100-3P!
Solid drill (MSD) & Solid drill with coolant hole (MSDH)
Alternative choice for both type.
Low cutting resistance type edge
Low cutting resistance type edges guarantees better surface finish and chip breaking.
Since it has self centering function, pre-centering cut is not necessary.
Rigid neck of drill
Rigid neck design prevent breakage of neck.
En-larged chip pocket
Optimal chip pocket
Chip pocket
Conventional drill Mach drill
Wide chip pocket area.
125% wider chip pocket than VSD, Better chip evacuation.
Chip pocket
Torsion rigidity increased
Special design has been employed to enhance rigidity of flute part where could be weakened by en-larged chip pocket area.
Better lubrication
The new TiAlN s excellent lubrication property provides good chipping resistance on cutting edge and reduced friction during
chip evacuation.
Post treatment for better chip evacuation
Since special design of cutting edge provides good chip evacuation, drilling without step-process is possible.
