HSMT12-12F11 & HSMT16-16K16 Thread Milling Set: 1/2" & 5/8" Internal Thread Mill Boring Bars with 20pcs Carbide Inserts (10x 11IR & 10x 16IR AG60) for Steel & Stainless Steel

HSMT12-12F11 & HSMT16-16K16 Thread Milling Set: 1/2" & 5/8" Internal Thread Mill Boring Bars with 20pcs Carbide Inserts (10x 11IR & 10x 16IR AG60) for Steel & Stainless Steel

• This professional set includes both the HSMT12-12F11 (1/2" shank) and HSMT16-16K16 (5/8" shank) internal thread milling bars. They cover a combined pitch range of 0.5mm to 3.0mm, providing a complete toolkit for machining internal threads in various hole sizes.
• The set includes 20 high-quality AG60 carbide inserts: 10x 11IR and 10x 16IR. The inserts come in specialized coatings (Gold for steel, Purple/Black for stainless steel), offering superior wear resistance, heat resistance, and anti-built-up-edge properties for optimal finish and tool life.
• Both boring bars are manufactured from 42CrMo steel and undergo high-temperature quenching and hardening. This process ensures high hardness, superior vibration damping, and resistance to deformation, enabling powerful and stable cutting even in demanding conditions like cast iron machining.
• The combination of rigid, shock-resistant tool holders and precision-ground carbide inserts allows for high-speed machining with excellent accuracy. This setup is designed to deliver high-precision threads, long service life, and reliable performance in both clean and harsh workshop environments.
• Get started immediately. The package includes: 1x HSMT12-12F11 Boring Bar, 1x HSMT16-16K16 Boring Bar, 10x 11IR AG60 Inserts, 10x 16IR AG60 Inserts (a mix of coatings for different materials), and the necessary mounting screws (M2.5x6 and M3.5x10).
