Hertel K027741AS25 M6x1.00 Straight Flute Tap Tin Hss

Product Description

The HERTEL K027741AS25 is a straight flute tap designed to cut M6x1.00 metric coarse internal threads in a wide range of workpiece materials. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers improved surface hardness and wear resistance compared to uncoated taps. The plug chamfer style distributes cutting load across several leading threads, making it well suited for through-hole applications. With 4 flutes and a 6H class of fit, this tap produces threads that meet standard metric tolerance requirements. Overall length is 2.5 inches and the tool weighs 0.35 pounds.

This tap is used in machine shops, maintenance and repair operations, and production environments where metric coarse threads must be cut or reconditioned. The plug chamfer makes it a common choice for through-hole tapping on ferrous and non-ferrous metals. It is compatible with standard tap handles and CNC or manual tapping attachments. Right-hand thread direction is standard for conventional metric fastener applications.

Key Features

• M6x1.00 metric coarse thread form for standard metric fastener compatibility
• High-speed steel construction for durability across a broad range of materials
• Titanium nitride (TiN) coating improves wear resistance and tool life
• Plug chamfer distributes cutting load - suited for through-hole tapping
• 4-flute design with 6H class of fit and D5 thread limit for consistent tolerance
• Right-hand thread direction, 2.5 inches overall length

Compatibility

Designed as an OEM-style replacement or direct-use tap for standard M6x1.00 metric coarse through-hole tapping operations using conventional tap handles or tapping heads.

Installation Notes

This tap should be installed by a machinist or qualified tooling technician familiar with standard tapping procedures. Ensure the workpiece is securely fixtured and the tap is properly aligned before beginning the cut to prevent thread damage or tap breakage. Use an appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Always reverse the tap periodically to break chips when hand tapping in tough materials.
