Hertel K027741AS M6x1.00 Straight Flute Tap 4 Flutes 6H Hss

Product Description

The HERTEL K027741AS is a straight flute tap designed for cutting M6x1.00 metric coarse internal threads. Made from high-speed steel with a bright, uncoated finish, this plug chamfer tap is suited for through-hole and blind-hole tapping applications where chip evacuation is managed manually or with cutting fluid. The 6H class of fit and D5 thread limit deliver consistent, tolerance-controlled threads for general machining work. Overall length is 2.5 inches and the tap weighs 0.35 pounds. Machinists and tool and die professionals reach for this tap when accuracy and repeatability in metric threading are required.

This tap is used in manual and CNC tapping operations on ferrous and non-ferrous materials. The straight flute design works best in through holes or short blind holes where chips can be cleared without helical flute geometry. Typical applications include machine shops, maintenance and repair operations, and production environments where M6 metric coarse threads are a standard requirement. The plug chamfer style provides a gradual lead-in, making it suitable for general-purpose threading rather than starting in a blind bottom condition.

Key Features

• M6x1.00 metric coarse thread form for standard metric fastener applications
• High-speed steel construction provides durability across a range of workpiece materials
• Plug chamfer with 4 flutes for stable cutting action and general-purpose use
• 6H class of fit with D5 thread limit for precise, repeatable thread tolerances
• Bright, uncoated finish suitable for use with cutting oil or tapping fluid
• 2.5 inch overall length compatible with standard tap holders and tapping heads

Compatibility

Designed as a direct-fit replacement for standard M6x1.00 metric coarse straight flute plug taps used in manual tap handles, tapping attachments, and CNC rigid tapping setups accepting straight shank tooling.

Installation Notes

This tap should be installed by a qualified machinist or tooling technician familiar with tapping operations. Ensure the workpiece is securely fixtured and the tap is properly aligned with the pilot hole before engagement to prevent tap breakage. Always apply appropriate cutting fluid or tapping compound to extend tool life and improve thread finish. Follow applicable shop safety procedures and machine tool manufacturer guidelines when setting spindle speed and feed for tapping cycles.
