Square CNMG1606 CVD Coated Tungsten Carbide Inserts For Cast Iron Machining
Square CNMG1606 CVD Coated Tungsten Carbide Inserts For Cast Iron Machining
Why choose tungsten carbide inserts?
CVD-coated carbide is suitable for low- to high-speed machining, from finishing to roughing. High toughness and crack resistance result in stable machining.
The various combinations with 3D chipbreakers solve problematic chip evacuation and enable high-speed machining at high feed.

Features of our carbide inserts?
1. Effective chip control & perfect turning surface
Provides perfect turning surface of the workpiece. Excellent and reasonable Chipbreaker design, removing the chips smoothly and taking away the heat of the rubs of the workpiece.
2. Higher production, long tool life
Long tool life means you need less time changing the inserts while machining. A reliable and safe performance every time.
3. CVD coating ensures the high wear resistance
The layer of the CVD coating with the thickness around 8um-20um which guaranteed the high wear resistance.
4. Less tool breakage, cost down of each component
Saving costs and reducing the cost of each component to increase the profits. The high wear resistance makes the long service life of the carbide inserts, which means you could saving more budget on purchasing the inserts.
Factors that influences chip breaking
- Insert geometry: Based on the width of chip room and the design of micro- and macro geometry, the chip will be open or more compressed
- Nose radius: Smaller nose radius controls the chip more than a bigger nose radius
- Entering (lead) angle: Depending on angle, the chip is directed in different ways; towards shoulder or out from shoulder
- Cutting depth: Depending on the workpiece material, a larger cutting depth will influence the chip breaking, leading to bigger forces to break and remove the chip
- Feed: A higher feed will in general create stronger chips. Can in some cases help chip breaking and chip control
- Cutting speed: Change of cutting speed can influence the chip breaking performance
- Material: A short chipping material (for example cast iron) is in general easy to machine. For materials with excellent mechanical strength and resistance to creep
(the tendency for solids to slowly move or deform under stress, for example, Inconel), the chip breaking is of greater concern
