  INSERT GUNDRILL : IDH SERIES
DONGSAN TOOL IDH SERIES GUNDRILL consists of a cutting insert and two guide pads, and is a tool that can be used for deep hole drilling like conventional brazing gun drills. By applying a 4-segment chip breaker to the insert, deep hole drilling is possible at twice the drilling speed compared to conventional brazing gun drills.

  - Cutting insert has two cutting edges & two polished guide wipers for high hole surface quality
  - Longer guide pad provides better straightness & hole size accuracy compared with other companies
  - Chip breaker makes improved drilling performance & smooth surface roughness by splitting long chip
    into 4 small chips
  - Hole Dia. accuracy : -0.03 ~ +0.02mm
 
     
 
 
     
 
Advantage
1. Drilling speed improved by chip breakers and PVD coating
2. Hole surface quality improved by chip breakers and PVD coating
3. Tool life improved by chip breakers and PVD coating
4. Hole size accuracy improved by polished body, insert and pads
