Advantages of SNMG120408-MA turning insert for machining steel parts
In the field of turning, choosing the right blade directly affects efficiency and cost.
SNMG120408-MA is a stable and reliable negative rake blade that performs very well in steel processing and is the preferred blade model for many processing plants in mass production.
So, what are the advantages of this blade? Why is it worth choosing? Let’s take a look.
1. What is SNMG120408-MA?
Let’s take a brief look at the model:
S: square blade with strong anti-collapse performance
N: 0° back angle, negative rake angle design
M: medium precision, strong adaptability
G: with center hole and fixed groove, double-sided
120408: side length 12mm, thickness 4.76mm, blade tip radius 0.8mm, suitable for medium-cut deep processing
MA groove type: Puwei’s special chip breaker groove developed for semi-finishing and finishing of steel
2. Two major advantages of SNMG120408-MA in processing steel parts
High blade strength and excellent anti-breakage performance
SNMG is a square design with strong edge strength, which is particularly suitable for processing steel with high hardness or intermittent cutting, such as:
45# steel, 40Cr, 20CrMnTi, bearing steel, etc.
Compared with triangular and diamond blades, it can withstand large feed and large cutting depth, is not easy to break, and has a longer life.
Double-sided use, high cost performance
SNMG is a double-sided 8-edge blade, each with 4 cutting edges × 2 sides = 8 available cutting edges, which greatly improves the cost performance.
Especially in large-scale steel processing, the replacement frequency is low and the unit cost is low, which is very suitable for large-scale production enterprises.

4. Different requirements for processing steel parts vs stainless steel
| Comparison Items | Steel parts (such as 45# steel, 40Cr) | Stainless steel (such as 304, 316) |
| Material hardness | Medium, moderate cutting resistance | High toughness, easy to stick to the knife, high cutting resistance |
| Thermal conductivity | Good, heat conduction is easy | Poor, heat concentrated on the cutting edge, easy to break |
| Processing Difficulties | Smooth chip removal, but wear resistance is required | Easy to stick to the knife, difficult to break chips, fast temperature rise |
| Workpiece surface roughness | Easy to obtain smooth surface | Easy to be scratched or scratched, and the finish is difficult to control |
Steel processing: pursue cutting efficiency and durability, can use higher feed and speed, suitable for large-scale production line operations
Stainless steel processing: pay more attention to finish and cutting stability, require low speed, light cutting + strong cooling, it is recommended to choose stainless steel special groove
