D-cut narzędzie
Cut any hole with helical machining!
Special cutting edge design enables helical machining
Special tools suitable for high-mix production
Various hole diameters handled by helical machining
20% less power consumption due to lower cutting resistance
Reduced spindle power achieves downsizing
Amazing facts!
── Introducing ideas and technologies ──
D-cut tool supports various hole diameters with a single tool by helical machining.
High-speed machining is realized with the most suitable cutting edge material. Low-resistance machining is achieved with multi-edge specifications and a unique edge runout adjustment mechanism.
Reduced spindle load enables spindle downsizing (in case of a conventional rough boring machine max diameter #50 to #40!).
This is the point!
Single tooling with helical machining
Excellent!

Good!
More than 50% cutting resistance reduction
Reduced power consumption
Good!
20% power consumption reduction
Development / product concept
“Current status and challenges”
- There is a growing need for multiple-product production in the manufacturing field.
- However, in order to accommodate the different diameters of each workpiece, tools that match each hole diameter are required, which increases new investment in equipment and tools.
“Development points”
- The “D-CUT TOOL” uses helical machining, enabling it to handle a wide variety of workpieces and reducing the number of tools.
- Furthermore, the unique cutting edge and run-out adjustment mechanism enables low-resistance machining, resulting in “cost reduction” and “equipment downsizing.
