A balanced design combining sharpness and cutting edge strength, to achieve a high efficiency feed rate off = 1.6mm/rev!

• High Accuracy Reaming

Excellent cutting edge quality free of microchipping realizes good hole surface quality

• Long and Stable Tool Life – Dedicated Coating for Reamers

High quality, high hardness, high strength and excellent wear resistance and thermal resistance.

• Coolant Mechanism by Application

• Applicable Hole Shapes

Achieving high precision machining in ultra-high efficiency machining
Maximum feedrate of 7,500mm/min

Modular extension arbor combined with a shank with run-out adjustment mechanism provides a higher degree of freedom for tool overhang.

2 face tapered contact (HSK standard) is used for positioning with a random insert repeatability accuracy of less than 4μm

Achieving high efficiency with high speed, high feedrates

• Compatible with a wide range of cutting conditions allowing cutting conditions and coolant control to be less strict.
• Minimum cutting length design eliminates biting or tearing etc. for improved quality and reliability.
• Improved reliability in quality and tool life with indexable inserts system, as well as eliminating problems associated with inconsistent tool life of using regrind tools.
• ø12.0~30.0mm sized inserts are stocked while ø11.9~140.6mm sized inserts are made-to-order.

Can be used as a self-guide tool by attaching guide pads to the holder

Nano-Polycrystalline Diamond Tool “SUMIDIA Binderless”

• SUMIDIA Binderless is a polycrystalline diamond that directly binds nanometer-sized diamond particles with high strength without using binders. SUMIDIA Binderless is harder than single-crystal diamond and has no cleavability. Therefore, it enables machining of hard brittle materials such as carbides and enables new machining methods.
• SUMIDIA Binderless is a pure diamond, but, unlike single-crystal diamonds, has no anisotropy. Therefore, it displays excellent wear resistance with less uneven wear.
• Thanks to its polycrystalline structure, SUMIDIA Binderless has no cleavability peculiar to single-crystal diamonds and displays excellent fracture resistance.

Comparison of Structures and Hardness

Mold Finish Master SUMIDIA BINDERLESS Ball-nose Endmills “NPD series”

The NPD series achieves direct mirror finishing of carbides, which is impossible for existing single-crystal or polycrystalline diamonds, by utilizing a harder nano-polycrystalline diamond cutting edge.

Ideal for Finishing of Hard, Brittle Materials Including Carbide

• Provides excellent machined surface quality thanks to the sharp cutting edge and optimized edge treatment.

Enables High-Precision Machining and Achieves Long Tool Life

• Maintains excellent dimensional accuracy for a long time thanks to the high contour accuracy of the cutting edge and the excellent wear resistance of diamonds.
