Dormer Threading Tap HSS 1-Piece 1.25mm Pitch Metric Standard Machine Tap M8 Thread

This is a high-performance machine tap designed for threading both blind and through holes in specific materials. It is manufactured from a special powder metallurgy tool steel, ensuring unbeatable toughness, edge strength, and wear resistance. With its unique features, this tap provides problem-free threading and improved accuracy.

• Constructed from premium-grade powdered metal cobalt high-speed steel (M35), the E471M8 tap offers exceptional toughness and wear resistance
• The tap design significantly reduces axial forces, enhancing thread accuracy
• By minimizing torque, this tap reduces machine wear and the risk of chipping or breakage
• The special flute geometry prevents swarf nesting, reducing the risk of re-cutting swarf during reversal
• The Yellow, Red, and Blue Shark spiral flute taps feature an edge treatment that increases strength and minimises micro-chipping on the cutting edges, improving overall performance and tool life

• Ideal for threading non-ferrous materials such as brass and bronze
• Suitable for continuous holes with a depth of 2.5 times the diametre (2.5xD)

The E471M8 tap is excellent for threading non-ferrous materials, including brass and bronze.

The recommended tapping depth is 35 mm (2.5 times the diametre).

Yes, it is specifically designed for threading both blind and through holes.
