Indexable insert drills series 336/337

Indexable Insert Drills Series 336/337 generation of the 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.



A product of:


High strength and excellent chip evacuation space

  • Large, reinforced helical flutes or straight flutes design

  • Through tool coolant

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


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

KAB6 and KAB7 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 KAB6 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

  • KAB6 connection ø3/4" to ø2-1/2" and ø31mm to ø61mm
  • KAB7 connection ø2-5/8" to ø2-7/8"

Insert Drill Lengths

  • 2xD and 3xD for all sizes



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
  • Through tool coolant supply to the cutting edge
  • Suitable for use as rotating or stationary
  • With adjustable drill holder for hole diameters with fractional sizes such as core bores or rough bores before finishing (adjustment range according to table)

KAB6 Connection Provides:

  • Very high clamping force, a short gauge length and a large seating diameter
  • Suitable for drilling under extreme conditions such as inclined surfaces, semi-circle bores and transverse bores

Carbide Inserts

  • Same insert type for inner and outer insert
  • Indexable inserts for all kinds of workpiece materials, with 4 true cutting edges

Insert Drill Sizes

  • KAB6 connection, ø16mm to ø30mm

Insert Drill Lengths
