Tungaloy SDMB26152 AH120 & GH330 Inserts
Professional Slotting & Side Milling | Heavy-Duty PVD Grades | Made in Japan
Which grade should I choose for heavy-duty steel milling?
The Tungaloy SDMB26152 series represents the pinnacle of heavy-duty square carbide milling technology. Engineered for deep slotting and aggressive side milling, these inserts are available in two world-class PVD grades: AH120 for maximum toughness and GH330 for superior wear resistance. Manufactured with high-precision standards in Japan, the SDMB26152 ensures structural integrity under high cutting forces, making it the primary choice for industrial-scale CNC machining of ISO P (Steel) and ISO K (Cast Iron).
Dual Grade Versatility
AH120: Best for interrupted cuts and general steel.
GH330: Optimized for high heat resistance and stable machining of hard steels/cast iron.
High Fracture Toughness
The square geometry and thick cross-section are designed to handle high material removal rates (MRR) without the risk of catastrophic edge failure.
PremiumTec Surface
Tungaloy’s post-coating treatment smoothens the surface, reducing friction and preventing chip welding, which is critical for deep slotting deep inside components.

Recommended Cutting Parameters (Heavy Milling)
-
Cutting Speed (Vc): 80 - 200 m/min (GH330 allows for higher speeds in stable cuts)
-
Feed per Tooth (fz): 0.20 - 0.45 mm/t (Aggressive feed range)
-
Strategy: Use air blow for steel slotting; GH330 excels in dry milling cast iron.
4. Product Applications
- Heavy slotting in industrial structural frames.
- Side milling of large engine blocks and machinery bases.
- High-feed material removal in tool and die factories.
- Deep pocket milling where rigidity is essential.
5. Tool Compatibility
Compatible with **Tungaloy Slotting Cutters** and **Side Milling Cutters** utilizing the SDMB 26-series pocket design. Fits standard CNC horizontal/vertical milling centers with high torque spindles.

Voice of Professionals
⭐⭐⭐⭐⭐ "Incredible Toughness" - David B., USA
"AH120 grade is a lifesaver for interrupted cuts. These SDMB inserts handle our deep slots without any chipping."
⭐⭐⭐⭐⭐ "GH330 for Speed" - K. Wagner, Germany
"Switched to GH330 for our cast iron bases. We've pushed the speeds up by 20% and the tool life is still better than the competition."
⭐⭐⭐⭐ "Predictable Wear" - M. Sato, Japan
"Consistent Japanese quality. Very easy to plan our tool changes because the wear is so predictable."
⭐⭐⭐⭐⭐ "Perfect Slotting" - Lim T., Singapore
"The finish inside the slots is surprisingly good for such a heavy-duty insert. Excellent stability in our CNC."
⭐⭐⭐⭐⭐ "Fast Delivery" - F. Silva, Brazil
"Genuine product, well packaged. Shipping was faster than expected. Great technical support from CNCHome-Beyond."
8. FAQ - Professional Milling Center
Q: Should I use AH120 or GH330 for cast iron?
A: For stable, high-speed milling in cast iron, GH330 is superior. If you are dealing with heavy vibrations or old machinery, AH120 is the safer choice.
Q: Is this suitable for stainless steel?
A: These are ISO P/K optimized. For stainless steel (ISO M), we recommend Tungaloy AH3135 or AH130 grades specifically.
Q: What is the benefit of the 2.0mm corner radius?
A: The 2.0mm radius provides extreme corner strength, preventing edge breakdown during aggressive high-feed milling operations.
Expert Comparison: AH120 vs GH330
The AH120 grade is your "Problem Solver" for tough setups and interrupted cuts. The GH330 grade is your "Production Racer" for high-speed efficiency in stable conditions. Both utilize premium PVD coating to ensure that the 26mm cutting edge remains sharp and precise. Trust Tungaloy for your heavy industrial slotting requirements.
