At CNC Tools Depot, we supply a wide range of SNMG Carbide Inserts built for high-strength machining applications. With their square shape and negative rake design, SNMG inserts offer multiple cutting edges per insert—delivering maximum cost-efficiency, durability, and long tool life.

Machinists rely on SNMG inserts for medium to heavy turning operations, particularly on steels, stainless steels, cast iron, and superalloys.

🔹 What are SNMG Carbide Inserts?

The designation SNMG provides information about the insert’s geometry and tolerance:

• S = Square shape (90° cutting edge).

• N = 0° clearance angle (negative rake).

• M = Medium tolerance (general purpose).

• G = Single/double-sided insert with specific hole & chipbreaker style.

SNMG inserts are typically double-sided, offering 8 usable cutting edges, making them one of the most economical options for high-volume machining.

🔹 Applications of SNMG Inserts

SNMG carbide inserts are widely used in:

• Heavy-duty CNC turning on steels and stainless steels.

• High metal removal rate machining (MRR).

• Roughing operations on large components.

• Cast iron machining with enhanced wear resistance.

• General turning and facing in automotive, aerospace, and heavy equipment manufacturing.

• Interrupted cuts where insert toughness is crucial.

🔹 Types of SNMG Carbide Inserts

At CNC Tools Depot, we stock a variety of SNMG insert types for different materials and operations:

1. Uncoated SNMG Inserts

   • Best for non-ferrous metals and short-run jobs.

2. CVD-Coated SNMG Inserts

   • Ideal for steel and cast iron, with excellent wear resistance.

3. PVD-Coated SNMG Inserts

   • Designed for stainless steel and superalloys.

4. SNMG with Chipbreaker Geometry

   • For effective chip evacuation in roughing/finishing operations.

5. SNMG Steel-Specific Grades

   • Higher toughness to resist chipping in heavy-duty applications.

6. SNMG Universal Grades

   • One insert covering a wide range of materials for versatility.

🔹 Advantages of SNMG Inserts

• Economical – 8 cutting edges per insert (double-sided square insert).
