Dormer thread cutting and forming tools

Dormer Tools has launched a new programme of thread cutting and thread forming taps to meet a growing requirement for versatile tooling.

Named 'Spectrum', the cutting tools offer high performance across a wide range of engineering materials.

Spectrum thread cutting taps are manufactured from premium quality vanadium powder steel or HSCo for superior toughness and edge strength.

Dormer provide the tools with a choice of gold (bright flutes/thread) or steam tempered finish to provide a smooth cutting action with less build-up on the cutting edge.

Designed to promote a continuous production process, all spiral flute Spectrum taps feature a three radii flute profile with a constant rake angle that promotes the creation and subsequent evacuation of narrow, regular chips, resulting in negligible chip congestion.

Spectrum forming taps offer a chip-free operation with a stronger thread for hole depths up to 3.5xD.

The thread profile generates low torque for longer tool life and excellent surface finish, while the highly stable design reduces the risk of tap breakage. The same tap can be used for threading both through and blind holes, increasing its versatility.
