RT16.01W-2.50GMPB YBG202 Threading Insert
Versatile 2.50mm Pitch External Threading Solution for Steel and Stainless Steel
Product Overview
"Seeking a reliable external insert that provides stable tool life and precision for 2.5mm pitch threads in both carbon steel and stainless alloys?"
The ZCC.CT RT16.01W-2.50GMPB YBG202 is a professional-grade external threading insert built for consistency. The "GM" designation identifies its Partial Profile geometry, which is reinforced to handle 2.50mm pitch threading with optimized cutting forces and high edge stability.
Equipped with the YBG202 Grade, this insert features a multi-layer nc-TiAlN PVD coating. This grade is renowned for its balance of hardness and toughness, making it the perfect choice for shops machining a variety of Steel (P) and Stainless Steel (M) components.
Key Features
- Balanced YBG202 PVD Grade: Provides the necessary toughness to handle interrupted cuts while maintaining a wear-resistant surface for longer tool life.
- Reinforced 2.50mm GM Profile: Geometry optimized to reduce vibration and deflection, ensuring precise thread forms on 2.5mm pitches.
- Universal Material Coverage: One insert for both steel and stainless steel applications, simplifying inventory for general machine shops.
- Smooth Thread Finish: Advanced PVD coating reduces friction and heat buildup, resulting in a superior external surface finish.
