Hertel K027752AS M8x1.00 Metric Fine Straight Flute Tap

Product Description

The HERTEL K027752AS is a straight flute tap designed for cutting M8x1.00 metric fine internal threads in a variety of workpiece materials. Built from high-speed steel with a bright uncoated finish, this tap delivers reliable thread cutting performance in production and maintenance applications. It features a taper chamfer for gradual thread engagement and a right-hand thread direction with a D5 thread limit for controlled fit tolerances. Overall length measures 2-23/32 inches. Straight flute geometry makes it well suited for through-hole threading and materials that produce short, brittle chips.

This tap is used in machining, tool-and-die, and maintenance repair operations where metric fine threads are required. The M8x1.00 thread specification is common in precision assemblies, automotive components, and instrumentation work where a finer thread pitch provides greater clamping strength and finer adjustment than standard M8 pitch. It is installed by machinists, toolmakers, and maintenance technicians working with drill presses, CNC machining centers, or hand tap handles.

Key Features

• M8x1.00 metric fine thread specification for precision threading applications
• 4 straight flutes suited for through-hole tapping in brittle or short-chipping materials
• Taper chamfer allows gradual thread engagement and easier starting
• High-speed steel construction provides durability across a range of workpiece materials
• Bright uncoated finish for general-purpose use
• D5 thread limit ensures consistent fit class tolerances

Compatibility

Designed as a standard-shank straight flute tap compatible with tap handles, tapping heads, and machine spindles that accept the corresponding shank size for M8 taps.

Installation Notes

Secure the workpiece and ensure the tapped hole is properly drilled to the correct tap drill diameter before threading. Use appropriate cutting fluid or tapping compound to extend tap life and improve thread finish. Apply steady, even pressure and back off periodically to break chips when hand tapping. Always follow shop safety practices and manufacturer recommendations for speeds and feeds when machine tapping.
