AG90 Series Angle Heads

Vertical and Horizontal Operations Combined

AG90 Angle Heads, with a fixed 90° spindle angle, combine vertical and horizontal operations on one machine. They increase productivity by easily changing the angle of the cutter while utilizing the original workpiece setup. This improves overall accuracy and eliminates the potential for error created by multiple setups. The compact design minimizes overhang adding rigidity and strength, as does the standard BIG-PLUS® shank for CAT & BT versions. Three AG90 types available: NBS Type, HMC Type and Build-Up Type.

NBS Extra Long Type
BCV/BBT 50 & HSK-A100
Max 6,000 RPM

Available with 4" (100mm), 8"(200mm) and 12" (300mm) extensions. Any 50 taper or HSK-A100 size NBS head can be extended for drilling or milling on workpieces with long reach requirements.

Cutter Head Adjustable 360°

Reference faces are provided on both sides of all heads for easy setting of cutter directions.  


Superior Quality Components

All Angle Heads are equipped with hardened and ground chrome-nickel steel spiral bevel gears, super precision hardened and ground spindles, and high precision angular contact ball bearings.  


Innovative Sealing Method

The advanced non-contact sealing method prevents coolant and particle contamination better than any other sealing method.  


Unique Coolant Jacket  

Jacket allows coolant coming through the stop block to be efficiently directed to the tool cutting edge while simultaneously cooling the Angle Head.
