Dormer Threading Tap, M10 Thread, Metric Standard, Machine Tap

Dormer E200 Straight Flute Metric Machine Tap Bits

A range of cobalt metric pitch machine tap bits that meet stringent high-production machining demands due to significant resistance to wear and high temperatures. These tap bits have a short entry of 2-3 threads and the tap bit tolerance class is 6H. The taps cutting angle is 10° and the tap flutes are straight. These taps also feature a reinforced shank and a shiny surface treatment.
These excellent quality tap bits are ideal for tapping in blind or through-holes to depths up to two times their diameter.
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.

Features and Benefits:

• Material is HSS-E (High Speed Cobalt)- for toughness, increased performance and tool life
• M Machine Tap Straight Flute
• Metric thread type
• Right handed thread direction – designed to tighten when a head or nut is rotated clockwise
• Available in various sizes

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:
• Engineering
• Manufacturing

Standard: DIN 371

• 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.
• 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.
• What are the different material types available?
• HSS: High Speed Steel
• HSS-E: High Speed Cobalt
• HSS HM: High Speed Steel/Carbide
• HSS-E PM: HSS-E Powder Metallurgy Steel

Rolled Flute Taps

• Bright finish fluteless taps; for use on copper, aluminium, magnesium, brass, zinc etc.
• Flash chrome finish fluteless taps; for use on steel up to 850N/mm² tensile strength, free matching and austenitic stainless steel
• Made to ISO529 standard for tapping blind and through holes in a wide range of ductile materials
• Smooth non-cutting action produces greater thread formed strength, higher life expectancy and increased tapping speeds especially where excessive tension occurs
