Dormer Machine Tap, M8 Thread Size, Spiral Point, Metric Standard, Right Hand Thread, 90mm Length, HSS Material E471M8

Dormer E471M8 machine tap is designed for industrial and mechanical applications requiring accurate threading of M8 size metric threads. Made of high-speed steel (HSS) using premium powder metallurgy processes, this tap offers excellent durability and edge strength to ensure long tool life and precision results.

This spiral point machine tap features a right hand thread with a 1.25 mm pitch and an overall length of 90 mm. It is particularly effective for threading non-ferrous materials such as brass and bronze, making it well suited for manufacturing, automotive, and tooling industries.

The tap's specialized flute geometry significantly reduces axial forces and torque, enhancing thread quality while minimizing machine wear and reducing the possibility of tool breakage. The flute design also prevents swarf nesting, avoiding re-cutting of chips during reversal, which extends tool life and improves operational efficiency.

This product meets DIN 338 and ISO 529 standards, ensuring compatibility with industry requirements for machine taps. The recommended tapping depth is 2.5 times the diameter (approx. 35 mm), suitable for both blind and through holes, providing versatile use in precision machining.
