About Alberti

Alberti Angle Heads, made in Italy, are high quality, long life and rigid with exceptional slim design. Both standard and custom sizes and angles are available.

Key Competitive Advantages:

• Body is cast iron which improves thermal stability, rigidity and provides dampening properties
• Monolithic hardened steel spindle input & arbor increases resistance to bending stress by upto 25%. Especially important for extra length angle heads. It also improves balance and makes it possible to reach higher RPM without vibrations.
• Better angle head life from less vibrations and structural integrity.
• Monolithic construction.
• Slim design increases ability to access restricted areas
• Ability for long reach with slim body
• Improved accuracy and concentricity

Index Head

About the Index Head

Alberti Index Head PDF (2021)

The INDEX head is made of an INDEX module and a selected range of angle head to be combined together. The mechanism inside of the INDEX module is activated by 6 bar air pressure through the reference pin and block and allows the positioning of the output spindle to vary infinitely around 360°. The INDEX head is fully ATC and can reach 10,000 RPM with 10mm max collet.
