Indexable Milling I Solid End Milling I Holemaking I Turning 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.   • T he 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.  — L ow carbon steel (typically P0 and P1). • Better general hole quality (surface and dimension) thanks to theimproved chip flow: — No drifting of the tool body causing deviation in the hole size.— S tainless steels, such as AISI304, AISI316, and similar materials.— Titanium alloys, like Grade 2 and Grade 5. • Bird-nesting on the tool body is an issue.   — No contact of the chips with the hole surface causing bad finishing.  • V ibrations 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. Top Cut 4 Inserts Expansion — Long Chip Materials. -V38 P M S Ideal for long chip materials. widia.com 123 widia.com
