Super MultiDrillAK
- MAK Type
- BAK Type
- LAK Type / DAK Type
- General Features
- Performance
●Chip Removal Comparison
The SUPER MULTIDRILL AK type, a brazed carbidetip drill with Drilling depth L/D=5 using mist
through-tool oil holes, utilises a tough carbide substrate coupled
with the new ZX-coating. With double the conventional regrinding Serious damage due to chip blockage allowance provided, a lower running cost can be achieved. Drilling Depth
- Characteristics and Application
- Stable tool life of up to 1.5 times Tough substrate with new ZX-coating improves fracture resistance and tool life.
Double the regrinding possibilities MultiDrill LAK Type Comp. Drill
Longer carbide tip portion provides double the allowance for regrinding. Drill: ø18 Work Material: S50C (230HB) Using Mist
- vc=50m/min f=0.3mm/rev H=90mm (L/D=5)
Unique flute design for using mist
Both flute shape and flute surface quality is designed for drilling depths of L/D=5 using mist.
