Indexable Insert Drills

Series 336/337


Indexable Insert Drills Series 336/337 generation of the BIG KAISER insert drills have straight flutes. This design guarantees a short distance for chip evacuation and high radial and torsional rigidity. Series 336 with through the tool coolant, directed on both sides at the cutting edges will guarantee optimum cooling and chip evacuation. The 337 drills are suitable for drilling under extreme conditions such as inclined surfaces, semi-circle bores and transverse bores. Made of case hardened steel construction for maximum rigidity and toughness.

Please note: We have decided to change our tool connection description of KA/KAB to CK/CKB to be consistent with how the product is referred to globally. There is absolutely zero geometric difference between a tool marked KA/KAB and CK/CKB, it was simply a way to differentiate North American inch tools from metric tools sold throughout the rest of the world.

High Strength and Excellent Chip Evacuation Space

High Strength and Excellent Chip Evacuation Space

  • Large, reinforced helical flutes or straight flutes design

  • Through tool coolant


  • Modular CKB connection allows for use on our standard shanks, coolant inducers and adjustable drill holders




Two Types of Indexable Insert Drills


Product Image

Series 336


Insert Drill Features:


  • 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 run-out.
  • Minimum gauge lengths.
  • Versatile CKB6 connection for all diameters 3/4" - 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




Product Image

Series 337


Insert Drill Features:

  • Straight flute design guarantees a short distance for chip evacuation, high radial and torsional rigidity, and very high cutting performance
  • Clockwise cutting, with 4-edge inserts, also suitable to enlarge pre-drilled holes
