High-precision small-diameter solid drill
KDA Mini
Features
New concept "Triple & Double Margin*" realizes high precision and stable machining
The margin geometry at the end and middle of the drill is optimized to achieve high-precision, stable drilling.
End portion has triple margins. Three sets of margins guide the cutting at the entry point, improving cutting accuracy.
The middle section has a double margin, ensuring ample space for chip evacuation and reducing chip problems.
* Type C (with coolant hole) only
New coating MEGACOAT NANO EX for long tool life
The newly developed proprietary coating MEGACOAT NANO EX achieves long tool life. "Double lamination technology" that laminates two types of special nano-layers in multiple layers achieves high levels of wear, welding and chipping resistance.
Case Study
Machine parts SUS316L
While competitor products frequently fractured due to chip entanglement resulting in unstable tool life, KDA Mini achieves stable machining with smooth chip control

(Customer evaluation)
Machine parts SUS304
By switching from a competitor's product (without coolant holes) to the KDA Mini Type C (with coolant holes), machining was significantly improved, achieving 2.8 times Machining efficiency and 2.4 times Tool life.
