Indexable Drills Top Cut 4™

-V38 Chipbreaker

Productivity

  • Eliminates the formation of bird-nesting on the tool in long chip materials drilling.
  • Improves the chip formation dramatically to guarantee a smooth chip flow.
  • No machine stops due to bad chip evacuation on low carbon steels, stainless steels, and titanium — high process reliability.

Performance -V38 Chipbreaker Application Areas

  • Larger feed rate window compared to the -V36 geometry when The new -V38 geometry is the first choice when: applied to low carbon steels and stainless steel. The drilling application with Top Cut 4™ platform
  • -V38 geometry is available on the inboard insert, as well as on the bodies and inserts is applied to: outboard insert. — Low carbon steel (typically P0 and P1).

— Stainless steels, such as AISI304, AISI316, and similar materials.

  • Better general hole quality (surface and dimension) thanks to the

— Titanium alloys, like Grade 2 and Grade 5. improved chip flow:

  • Bird-nesting on the tool body is an issue.

— No drifting of the tool body causing deviation in the hole size.

— No contact of the chips with the hole surface causing bad finishing.• Vibrations are generated due to a bad chip flow. Chip can’t evacuate
from the hole and generates big noise during machining.
Technical Details• Bad surface quality caused by the chip in contact with the hole.
  • Bigger hole size. Bad chip flow can generate tool drifting.
  • PSTS inserts.
  • Lower power consumption and less torque are needed.
  • Special edge geometry for more effective chipbreaking action.
  • First choice for low carbon steel, stainless steel, and super alloys.
  • Periphery insert with wiper land.

Disconnected edge with balanced cursive and straight edges.

Donut-shaped, dimple design chipbreaker. 2° rake angle with sharp edge.
