TWIN CUTTER BORING HEADS: SERIES 319 SW & 315 TWN

Boring Range .787"-8.000" (20mm-203mm)

319 twin cutter boring head

The KAISER 319 SW series twin cutter boring heads are the newest design in our twin cutter boring program. As with the 315 series, 319 is designed for heavy duty rough boring and semifinishing operations.

This new twin cutter series has a unique design feature allowing different roughing methods without the need to change components or use mechanical systems to adjust insert height. Simply reverse the insert holders to switch between balanced and stepped cutting!

Ground serrations on the mating surfaces of both tool body and insert holder permit a rigid connection and an accurate tool length. A diameter scale on the insert holders allows diameter adjustment without a presetter. Tool body and insert holders are completely protected against corrosion by a high quality coating.

SERIES 319 "SW" ROUGH BORING HEADS DIAMETER .787"-8.000"



319 SW Series


  • KAB1-KAB7 diameter range of .787" (20mm) to 8.000" (203mm)

  • CKN6-CKN7 diameter range of 2.677" (68mm) to 8.000" (203mm)

  • A straight shank small diameter version is available for .630" (16mm) to .827" (21mm) click here to learn more

  • Different roughing methods without additional components and without length adjustment

  • Rotationally symmetrical roughing (RSS), for stock removal up to 10% of the final bore diameter with high feed rates. Double offset roughing (DVS), cutting edges displaced in diameter and height, for stock removal up to 20% of the final bore diameter with half the feed rate

  • Insert holders accept large, ISO standard positive geometry inserts (CC, SC & SP) for reduced cutting forces

  • Insert holders feature extra chip space for blind hole roughing and features coolant-through direct to cutting edge

  • Coated body and insert holders for complete protection against corrosion

  • Height accuracy due to ground serrations on both ends between tool body and insert holder

  • Presetting of diameter & height without presetter thanks to fixed tool height and a diameter scale


SERIES 319 "SW" ALUMINUM ROUGH BORING HEADS DIAMETER 2.677"-8.000"



319 SW Series

  • CKN6-CKN7 diameter range of 2.677" (68mm) to 8.000" (203mm)

  • High strength aluminum tool body for reduced tool weight

  • Ideal lightweight solution for rough boring on 30 and 40 taper size machines with limited tool weight for automatic tool change

  • All standard (steel) SW accessories and insert holders are possible including back boring, stepped cutting and chamfering

The set contains one insert holder and one blank piece.


314 and 315 twin cutter boring heads

KAISER 315 twin cutter boring heads are designed for heavy duty rough boring and semifinishing operations. Their compact, sturdy design and positive geometry allow almost chatter free operation even in interrupted cuts and high cutting speeds. Twin cutter boring heads can outperform single cutter finishing heads by a factor of up to 4 times. Large stock allowances and high feed rates permit high production while assuring optimum bore roundness and location, two important quality features for today's tighter control of part geometry. In many cases, these tools can eliminate the need for semi-finishing cuts due to the superb balance of cutting forces, even under the most severe casting core shift.

KAISER 315 series tools use ISO standard inserts with positive cutting geometry for reduced cutting forces. The top clamp free mounting of the inserts and wide open chip spaces between the insert holders allows perfect chip formation and evacuation. Different grades and geometry's of carbide and silicon nitride inserts are available to optimize all application criteria.
