A range of machine metric thread spiral flute HSS-XS1 taps from Dormer with a tap bit tolerance class of 6H. Specially formulated high helix of 45º allows adequate room for chip formation and rapid and smooth chip evacuation at high cutting speeds for threading blind holes of up to 2.5 x diameter of the tap used. The 3 radii flute profile gives a constant rake angle all along the flute length, while the short thread length means low torque and better chip evacuation.

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. Taps can be used in machines like drill presses or with hand tools such as a tap wrench.

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:

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 Spiral Flute Taps.

What is chamfer?
Chamfer is a term that refers to the size of the threads on a tap that taper, allowing for the cutting thread to be gradually enlarged.

This threading tap by Dormer is a high-quality machine tap designed for M6 threads. With the use of HSS-XS1 material, this tap offers precision and reliability in tapping operations. The spiral flute design ensures efficient threading with a right-hand thread direction. The overall length of 66mm and a shank diameter of 6.3mm make it suitable for a wide range of industrial applications.
