(Unit : mm)
Feature
- Application : Drilling for High Hardened Steels[Quenched Steels, Tempered Steels (Under HRc 70)
- Advantage : Special Design
- Minimum of cutting load through special thinning Good chip removal Powerful Drilling
DREAM DRILLS
for HIGH HARDENED STEELS
Low Helix
The low Helix angle maximizes tools’ rigidity and stability with less deflection
Special Thinning (R+U Thinning)
Unique drill point geometry with special thinning to minimize cutting workload, axial thrust loading and heat generation
Coating
TiAlN nano coating combines high hardness with high thermal stability against oxidation, allows machining the upper level of hardened steels HRc 50-70.
Polished Flutes
Polished flutes improve coating addition, with better chip control and evacuation.
