Description
Dormer's E621 metric machine taps can be used to create threads to suit helicoil inserts in many materials including stainless steels, steels and aluminium and are manufactured conforming to the International Standards Organisation (ISO). Made from High Speed Steel for longer tool life and superior performance, the taps have a bright finish which stops workpiece material from sticking to the cutting surfaces of the tool, ensuring a clean and accurate thread. E621 metric machine taps for helicoil inserts have a spiral flute for threading blind holes (holes which stop part way through the workpiece).

Key Features

Bright finish - prevents work piece material from sticking to the cutting edge

Premium HSS material - high speed steel provides superior performance and extend tool life

spiral flute - designed for efficient threading of through and blind holes

ISO Standard - manufactured conforming to the international standardisation organisation

Versatile product - first choice for tapping aluminium, also suitable for steel, stainless steels and cast iron
