Frequently Asked Questions
What materials are MGMN/ZT*D insert grades suitable for?
MGMN/ZT*D insert grades are suitable for a wide range of materials including P Steel, M Stainless Steel, K Cast Iron, N Non-ferrous Metals, S Heat-resistant Alloys, and H High-hardness Materials. The specific grade selected determines the optimal material compatibility.
What is the difference between GP5125, DP5125, DP5220, and NA20 insert grades?
Each grade is engineered for different cutting conditions. GP5125 and DP5125 are well-suited for steel and cast iron machining, DP5220 offers enhanced performance on stainless steel and cast iron, while NA20 is specifically designed for non-ferrous metal applications such as aluminum and copper alloys.
What do the symbols ●, ○, and ▲ mean in the insert grade table?
The symbols indicate availability and suitability: ▲ (Excellent – In Stock) represents the highest recommended grade available immediately; ● (Good – In Stock) indicates a good-performing grade that is also in stock; ○ (On Request) means the item is available by special order and not held as standard stock.
What width range do MGMN boring inserts cover?
MGMN boring inserts cover a width (b) range from 1.5 mm to 6 mm, accommodating various grooving and boring requirements. The MGMN-G type starts at 1.5 mm, while the MGMN-M and ZTED-MG types extend up to 6 mm width.
What is the difference between the MGMN-G and MGMN-M chipbreaker types?
The MGMN-G chipbreaker is designed for light to medium cutting with smaller widths (1.5–2.5 mm), providing a sharp edge suitable for finishing operations. The MGMN-M chipbreaker covers a broader width range (2–6 mm) and is optimized for medium to heavy grooving and parting operations.
Are ZTED-MG inserts compatible with both continuous and interrupted cutting?
Yes, ZTED-MG inserts are designed to handle both continuous and interrupted cutting conditions. The chipbreaker geometry and carbide grade selection ensure stable performance under varying cutting environments, making them versatile for boring and grooving applications.
