Product Details

Dormer Set of Two E105 Fine Metric Thread HSS Hand Tap Bits

A range of manual fine metric thread HSS taps offered in a 2-part set (roughing and finishing).
Each set consists of a roughing tap bit which has a five-thread entry and the finisher has two. The tap bit tolerance class is 6H, the cutting angle is 10° and the tap flutes are straight.

These high-quality tap bits from Dormer are ideal for tapping in blind or through-holes.

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:

Material HSS (high speed steel) - for high durability and resistance to corrosion
M Hand Tap Straight Flute
Metric thread type
Right handed thread direction – designed to tighten when a head or nut is rotated clockwise

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 applications such as:

Standard: DIN 2181


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.
