DRILLS
SERIES 336 INSERT DRILL • Large, helical flutes reinforced at the edges provide highest strength and chip space • Through the tool coolant, directed on both sides at the cutting edges to guarantee optimum cooling and chip evacuation • Case hardened steel construction for maximum rigidity and toughness CKB6 AND CKB7 CONNECTION PROVIDES: • Highest stability by clamping the drill to the shank both axially and radially at the largest seating diameter • Lowest amount of drill runout • Minimum gage lengths • Versatile CKB6 connection for all diameters 3/4" to 2-1/2" allows more flexibility on smaller machines • Widest range of shanks and coolant inducers
CARBIDE INSERTS: • ISO standard WCMX inserts for both inside and outside cutting edges provide 3 indexes • Positive cutting geometry for reduced cutting forces • Different grades optimize cutting conditions
INSERT DRILL SIZES: • CKB6 connection, Ø3/4" to Ø2-1/2" and Ø31mm to Ø61mm • CKB7 connection, Ø2-5/8" to Ø2-7/8"
INSERT DRILL LENGTHS: • 2xD and 3xD for all sizes
