Micro Drill Short Flute Length & Long Flute Length

Introduction
Micro Drill(ADR) was sold in 1996, and added long-flute length(ADRL) and short-flute length (ADRS), the new type semi long flute length(ADRSL) was added after in 2015.
The smallest diameter of regular flute is from φ0.05 to φ0.02.(2015∼2016)
Deep hole processing is increased in small outer diameter
The sheet processing is increased in small outer diameter
Available for SOLID CARBIDE MICRO DRILL

　NC Pointing Drill ADP Series

Introduction
Special Guide -hole drills for use in drilling small holes.
Because the demands for the central drill with small holes and special guide-hole is
increase, this series type was added.
φ D: φ0.03mm∼φ3.0mm

Feature

• Best bright finish of hole position, hole tolerance
• Preventing the bending of hole position
• Preventing running the drill, the leading end is broken .

　Super precision Micro Drill ADR-SP

Introduction

• Best bright finish - Micro Drill
• Middle size of drill diameter 0.01mm increment series is standardized.
• This super precision drill provides under 2μtolerance of run-out accuracy and 
  lip height difference.
