B-KIDS závitník M30 DIN-376C R40 (6H) HSSE 800 strojný závitník

Creating precise M30 threads in through holes can be a challenge, especially when working with tough materials like alloyed steels. A tap that dulls quickly or produces inconsistent threads leads to rework and wasted time. This machine tap solves that problem with its cobalt-enriched HSSE steel and spiral point design, delivering clean, accurate threads and long tool life.

Who is it for

This tap is intended for machinists, metalworking professionals, and manufacturing facilities that need to produce metric coarse threads in through holes. It is suitable for use on CNC machines, machining centers, and manual tapping operations where high performance and reliability are required.

Main features

• Nominal thread diameter M30 with a 3.5 mm pitch, conforming to metric coarse thread standards.
• Thread tolerance class 6H ensures a standard fit for general-purpose fasteners.
• Manufactured from HSSE (high-speed steel with cobalt) for enhanced heat resistance and durability.
• Spiral point (gun nose) flute geometry pushes chips forward, ideal for through-hole tapping.
• Chamfer form C with 2-3 threads for easier starting and reduced torque.
• Conforms to DIN 376 standard for machine taps with reinforced shank.
• Bright finish reduces friction and improves chip flow.
• Right-hand cutting direction for standard clockwise tapping.

Tips

Use a suitable tapping fluid to extend tool life and improve thread quality. Ensure the tap is properly aligned with the hole to avoid breakage. For best results, use a tapping cycle with controlled feed and speed appropriate for the material being tapped.
