Dormer Threading Tap, M8 Thread, 1.25mm Pitch - E471M8

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.

Features & Benefits

• 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

Applications

• 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)

What materials can I use the E471M8 tap for?

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

What is the recommended tapping depth for this tap?

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

Does the E471M8 tap work well for blind holes?
