Dormer E500 HSS Straight Flute Coarse Hand Tap

A range of high-speed steel (HSS) straight flute hand taps from Dormer which are used to produce metric coarse threads in a variety of materials including steel, cast iron, copper, brass, aluminium alloys and plastics.

Threading taps are used to create threads for bolts in materials like metals and plastics. Threading taps work like a drill but due to the unique shape of a tap, when they are screwed into a piece of material screw threads are created.

Features and Benefits:

M Machine Tap Straight Flute
Suitable for tapping repeatable tolerance threads in through or blind holes by hand or machine
7° cutting rake angle
Bright finish
Manufactured to ISO 529 standards
Metric thread type
Right handed thread direction – designed to tighten when a head or nut is rotated clockwise
Material HSS (high speed steel) - for high durability and resistance to corrosion

Typical Applications

Taps and dies are used to create screw threads (commonly known as threading). Taps make nuts and a die makes a bolt. Forming threads using a tap is known as tapping, but using a die calls the process threading. Threading taps are used in:
Engineering
Manufacturing

FAQs

What is HSS?

An acronym for High-speed steel, HSS is generally the go-to type of steel needed for tap and drill bits due to their excellent heat resistance at high speeds. As a standard drill can spin upwards of around 500 - 700rpm, the friction can cause a substantial build-up of heat. Something which would not be wanted when working with wood and plastic.

What are the different types of threading taps?
The four most popular ones are:
Straight Flute Taps: most commonly used type of tap and suitable for blind or though hole thread production in most materials, mainly steel and cast iron. These collect chips in the straight flutes of the tool.

Spiral Point Taps: suitable for threading through holes. They push chips through holes ahead of the tool.

Spiral Flute Taps: intended primarily for threading blind holes. They pull chips back from the tip of the tool and up and out of the hole.

Forming Taps: produce a thread by pressing the material rather than cutting and no chips are created.

These Dormer taps are Straight Flute Taps. Straight flute taps and be used by hand and they can also be used in a machine if needed.
