Frequently Asked Questions
The LF9018 grade and CQ chipbreaker are optimized for steel machining, especially in turns that demand strong wear resistance and good chip control.
Yes — while it’s ideal for finishing to medium turning, the CQ chip-breaker handles a range of depths and feeds, making it versatile for different turning operations.
LF9018 is a high-performance coated carbide that resists abrasion and edge chipping. Its combination of toughness and hardness allows longer cutting times and reduced frequency of insert changes.
The CQ geometry helps to produce stable, well-formed chips that evacuate cleanly, minimizing issues like built-up edge and improving surface finish consistency.
-
It’s widely used in automotive, aerospace, die & mold, and general engineering — anywhere high-precision, high-volume steel turning is required.
