Split Sleeves are used together with Mandrels to permit a one-sided Cold Expansion operation whilst protecting the hole from damage.  They can only be use once are available in -S, … Read More

Mandrels are made from tool steel which has been heat treated to endure the severe tensile and compressive stresses to which they are subjected. Extra hard Mandrels may be ordered … Read More

Start Drills are used to produce new holes where considerable amounts of material removal is required.

Start Reamers are used to make start holes where only a limited amount of stock removal is needed and make optimal holes for the subsequent Cold Expansion process.

Finish Reamers are used to leave holes to  final size  holes prior to installing applicable fasteners.

The Combination Gauge ensures that the start hole is within specified tolerance with the  go/no-go gauge  and that the final holes lies within tolerance with the  go gauge.

The Mandrel Gauge  ensures that the mandrel has not been worn under tolerance.

The Puller Gun, powered by a hydraulic power supply,  pulls the mandrel through the sleeve and work piece.

Angleheads allows for right angled operations in areas with limited access. They attach to the Puller Gun and are available in different dimensions.

The Power Packs are heavy duty power units for capable of generation 700 bars of hydraulic pressure. The Pak Standard is used for generating high speed and maximum power whilst … Read More
