-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.
