The SCM Minimax AD 21 Semi-Automatic Boring Machine is a single head multiple boring machine with 21 spindles ideal for craftsmen and professional workshops.

Advantages

Drilling Head
Drilling head made from single-piece aluminium casting, to guarantee absence of vibrations. The boring unit runs on two rectified cylindrical guides which guarantee stability and precision. The machine is equipped with a mechanical revolver with 5 different boring depth adjustments. The new dust extraction system is incredibly efficient, and leaves the machine surprisingly clean!

Precise positioning
The mechanical gauge guarantees fast and precise positioning of the lateral fences.

Increased versatility
The quick-change chucks can be fitted with various types of bits for different operations, like boring hinges locations.

Controls
All controls are ergonomically positioned on the front of the machine. This includes the switch which sets the boring head at a 45° angle, allowing for an immediate changeover between operations. For perfect boring of large panels, the machine has a long 3000 mm fence with a scale and retractable stops. The fence is quickly mounted and removed easily.
