• PVD TiAN coating combined with high damage resistance
of the hard alloy substrate, has excellent heat resistance
and crack resistance, to achieve stable processing under
different working conditions.
GS4130 Purple gray
• The latest nano TiAIN coating with high toughness micrograined carbide substrate, achieve good wear resistance
and toughness.
•Suitable for unstable steel conditions and difficult to
process materials.
GPD7115 Purple gray
• High strength and toughness of subfine crystalline
carbide substrate with a new nano composite multilayer
PVD coating, bringing excellent wear resistance and red
hardness. Special surface treatment can effectively inhibit
the formation of debris nodules.
• Suitable for medium and low speed processing of steel.

be used as inside
or outside insert
Double twisted
coolant channel
Fist shape cutting edge
Optimized Inner and outer
insert structure design
● Having better performance of
chip control and cutting stability
——Balanced inner and outer
cutting edge force, result in
better stability
● Perfect cooling performance
——Cooling and chip removal more
sufficient，Intensified outer insert seat
Cooling groove design
Internal coolant outlet directly
inject insert rake surface
● Having better anti-fracture
——Eliminating drill body surface
stress and environment protection
——Chip remove is more smoothly,better
rigidity.
Local wide cutting edge
and small rake angle
Advanced surface treatment
technology
Optimized flute design
● Convenient for tool
management
——Structure is more rational
and chip removal smoother
