Hertel K020233AS Straight Flute Tap M8x1.00 Metric Fine Hss

Product Description

The HERTEL K020233AS is a straight flute tap designed for cutting M8x1.00 metric fine internal threads in a range of materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable performance in threading operations where a plug chamfer is appropriate for through-hole and semi-blind applications. The plug chamfer style provides a balanced lead-in, making it suitable for most standard threading tasks. With a D3 thread limit, the tap is ground to produce threads toward the high end of tolerance class, helping ensure consistent fit with mating fasteners. Machinists, tool and die workers, and maintenance technicians install this tap in manual or CNC tapping operations.

This tap is suited for metric fine threading work in ferrous and non-ferrous metals, plastics, and similar machinable materials encountered in manufacturing, maintenance, and repair environments. The straight flute geometry works best in shorter-chipping materials where chip evacuation can be managed without helical flute assistance. The M8x1.00 pitch is a common metric fine thread specification used in precision assemblies, automotive components, and machine tooling where a finer thread engagement is required compared to the standard M8x1.25 coarse pitch.

Key Features

• M8x1.00 metric fine thread for precision thread-cutting applications
• Plug chamfer with 4 straight flutes for balanced lead-in in through-hole and semi-blind holes
• High-speed steel construction for durability across a range of machinable materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• D3 thread limit ground for consistent high-tolerance thread fit
• Right-hand thread direction, standard for the vast majority of threading applications

Compatibility

Designed as a standard replacement or stock tap for M8x1.00 metric fine thread applications. Compatible with standard tap holders, tapping heads, and tap wrenches sized for a 0.3180-inch shank diameter.

Installation Notes

This tap should be installed by a qualified machinist or maintenance technician familiar with threading operations. Always ensure the workpiece is properly secured and the correct tap drill size for M8x1.00 metric fine threads is used before tapping. Apply an appropriate cutting fluid for the material being tapped to reduce heat and extend tap life. Reverse the tap periodically during manual operations to break chips and prevent binding or breakage.
