Super MultiDrill AK Type ● 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 Cutting Force ● 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 ● Unique flute design for using mist vc=50m/min f=0.3mm/rev H=90mm (L/D=5) Both flute shape and flute surface quality is designed for drilling depths of L/D=5 using mist. ■ Application Examples ●Automotive Components SCM440 (250HB) ■ Series Great improvement in tool life! Series Cat No. Diameter Range Drilling Depth Characteristics AK Type (mm) (L/D) Standard Type (MAK) ø13.6 to ø40.5 Up to 3 Up to 3 times more total tool life Competitor’s Long Type (LAK) ø13.6 to ø40.5 Up to 5 expectancy resulting from 1.5 times better tool life and 2 times more Deep Hole Type (DAK) ø13.0 to ø40.5 Up to 7 regrinding possibility. 0 100 200 300 (Hole) Standard Type (BAK) ø13.6 to ø30.5 Up to 3 Designed for drilling stacked sheets.
