Seco - Holemaking - Boring - Rough Boring Heads A750

The A750 rough boring heads are developed for highest possible boring performance:

High productivity

• Strong ‘twin cutters’ design for high metal removal: axial and radial insert holder locking by the unique central screw.
• Full insert performance is possible since the insert holder bending is limited by its face contact onto the head body’s front during machining.
• Large range of insert grades for all materials.
• Both 90° and 80° lead angle insert holders.
• Through coolant, directed towards the inserts.

Geometrical hole precision

• Achieving geometrical hole precision starting from cast, flame cut or drilled hole.
• Minimised unbalance thanks to a symmetrical design.

Easy setting

• Simultaneous or independent insert holders setting, by integrated coupling mechanism.
• Symmetrical or staggered settings possible.
• Easy assembly and interchange of the insert holders (only one clamping screw).
