Advantages of WNMG080404-HK turning insert for machining cast iron
Cast iron is a common but not “easy” processing material.
It is hard, brittle, and has a high carbon content. It is also prone to chipping, edge loss, and rapid blade wear during cutting. Facing these challenges, choosing the right blade is very important.
Among the many turning blades, WNMG080404-HK is a “powerful” representative when processing cast iron.
In this article today, we will take you to see what this blade is so strong about.
What is WNMG080404-HK?
This is a typical indexable carbide turning insert with a symmetrical hexagonal design and can be used on both sides.
W: Hexagonal insert with a tip angle of 80°
N: 0° back angle design, more rigid
M: Medium tolerance grade
G: indicates center hole, double-sided grinding
080404: indicates insert side length 8mm, thickness 4.76mm, corner radius 0.4mm
HK: represents cast iron (H) material, K is the chip breaker model
In short, this insert is designed for high-efficiency machining of cast iron and is suitable for roughing and semi-finishing.
TNMG vs WNMG: Which one should I choose?
Although TNMG inserts can also be used for turning cast iron, there are still differences between the two in structure and application scenarios:
| Type | Insert shape | rigidity | Number of available cutting edges | Processing adaptability |
| TNMG | triangle | generally | 6 | Suitable for finishing, soft materials or light cutting |
| WNMG | Hexagon | higer | 6 | More suitable for heavy load, intermittent and cast iron rough machining |
Therefore, if you need improved stability and blade life on rough surfaces or in mass production, WNMG080404-HK is more suitable for you.
