Boring Head Adapter 2MT – 1-1/2″ x 18 TPI Spare Shank Arbor for 2″ / 50mm Boring Head | MT2 Milling & Drilling Arbor

This Boring Head Adapter 2MT (MT2) – 1-1/2″ x 18 TPI Spare Shank Arbor is a high-precision machining accessory designed for securely mounting 2″ / 50mm boring heads onto machines fitted with a Morse Taper 2 (MT2) spindle. Manufactured to professional workshop standards, this arbor ensures excellent concentricity, superior rigidity, and vibration-free performance, making it ideal for accurate internal boring, facing, and precision machining tasks. Designed as a direct replacement boring head shank or spare arbor, this MT2 boring head adapter is suitable for a wide range of milling machines, drilling machines, and compatible lathes. The standard 1-1/2″ x 18 TPI male thread ensures broad compatibility with commonly used 50mm boring heads, while the integrated 10mm drawbar provision guarantees positive spindle retention and safe operation under load. Engineered from high-quality hardened steel, this arbor delivers long service life, excellent wear resistance, and consistent accuracy even during demanding workshop use. It is fully compatible with Miford machines and other MT2-equipped setups, making it a reliable choice for toolrooms, engineering workshops, and precision manufacturing environments.
