M24 x 3.0 Metric Coarse Machine Tap, 6H, HSS-E, DIN 376, Straight Flute, Through Hole

Cutting clean, accurate M24 threads in through holes can be a challenge without the right tool. This M24 x 3.0 metric coarse machine tap with 6H tolerance class is engineered to produce precise internal threads in a single pass, reducing rework and scrap. Made from HSS-E high-speed steel with cobalt, it offers enhanced wear resistance and heat hardness, making it suitable for general-purpose steels and non-ferrous materials.

Who is it for

This tap is ideal for machinists, maintenance technicians, and metalworking professionals who need reliable thread cutting in production or repair environments. It works with machine tapping equipment or manual tapping setups where a straight flute design is preferred for through holes.

Main features

• Metric coarse thread M24 x 3.0 mm, tolerance class 6H for standard fit
• HSS-E (cobalt high-speed steel) for improved durability and heat resistance
• Straight flute geometry optimized for through holes, allowing chips to flow forward
• Form C lead (2-3 threads) for easy starting and reduced cutting torque
• DIN 376 standard dimensions: 140 mm overall length, 40 mm thread length
• Uncoated bright finish for general-purpose applications
• External coolant supply compatible

Tips

Use appropriate cutting fluid and ensure proper alignment to maximize tap life and thread quality. For through holes, the straight flute design allows chips to be pushed forward, reducing the risk of clogging.
