Counterbores
BF-Cutter
The BF-Cutter was exclusively designed for back spot facing of capped bolt holes, sizes M6-M16, or 1/4"-5/8. It features the world’s smallest square indexable insert, (with 4 indexes), and is ideal for all steels, (including stainless), cast iron and aluminum.
The coolant-through capability helps cool down the back side cutting area, increasing tool life – a feature not available in most other models on the market. The BF-Cutter is available for minimum facing diameters. A unique, offset design allows for easy programming – simply offset the centers between the machine spindle and the hole when entering or exiting the hole with the cutter.

Centre drills
C-Centering Cutter
The C-Centering Cutter is a multifunction cutter capable of both spot drilling and chamfering. The coolant hole allows cooling of the cutting edge, which reaches high temperatures during spot drilling in particular, and enables immediate chip evacuation.
During spot drilling, the insert nose radius can be easily chipped with general cutters since the center has a peripheral speed of zero. At the nose radius on the C-Centering Cutter insert forms negative land, it has high chipping resistance and the tool life is significantly extended.

Tooling systems

Angle Head AGU30
Angle Head AGU30
Adjustable from 0° - 30°
BIG Kaiser Präzisionswerkzeuge AG
Angular heads
Angle Head AGU30
Universal AGU30 Type Angle Heads use a unique constant velocity joint to shed weight and allow for higher performance than other angle heads. The joint transmits enough torque to outperform traditional, spiral beveled gear 90° angle heads, while a low backlash design means better surface finishes with fine milling. The flange structure keeps rigidity at a constant despite the angle of the head, unlike a swing structure in which rigidity is dependent on the cutting direction. Also, because the mechanism is sealed, the AGU30 provides better coolant and chip proofing.

The spindle angle is adjustable from 0° - 30°, and is easily adjustable using the scale indication on the body. The cutter head is adjustable a full 360°.

Angle Head AGU90
AGU90 Type Angle Heads, with an adjustable spindle, (1° - 90°, 1° increments), 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. BIG-PLUS® is standard for all SK & BT versions, ensuring rigidity and accurate automatic tool changes.
