DORMER has expanded its range of multi-material tools with the addition of numerous new thread cutting and thread forming taps.

Carrying the brand name Spectrum, the product introduc tions target a growing require ment for versatile cutting tools that offer high performance across a wide range of engineering materials.

The Spectrum thread cutting taps are manufactured from either premium quality vanadi um powder steel or HSCo for superior toughness and edge strength, with a choice of gold (bright flutes/thread) or steam tempered finishes to provide a smooth cutting action with less build-up on the cutting edge.

The tools, designed to promote a continuous production process, feature a three radii flute profile with a constant rake angle.

This is said to facilitate the cre ation 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 stable design is said to reduce the risk of tap breakage.
