Hertel K027722AS M3x0.50 Straight Flute Tap Bottoming Hss

Product Description

The HERTEL K027722AS is a straight flute bottoming tap designed for threading M3x0.50 metric coarse internal threads in a wide range of metalworking and machining applications. Manufactured from high-speed steel with a bright, uncoated finish, this tap features 3 straight flutes and a bottoming chamfer that allows threading to the bottom of blind holes. The 6H class of fit and D3 thread limit deliver consistent tolerance control suited for precision fastener applications. Overall length is 1-15/16 inches. Right-hand thread direction is standard. Machinists and tool-and-die professionals rely on this tap for accurate metric thread production in production and repair environments.

This tap is intended for use in manual tapping operations or low-speed machine tapping on ferrous and non-ferrous materials. The bottoming chamfer style makes it the correct choice when threads must extend fully to the bottom of a blind hole, a common requirement in fixture work, equipment repair, and precision component manufacturing. Its compact M3 size is frequently used in electronics, instrumentation, and light mechanical assemblies where small-diameter metric fasteners are standard.

Key Features

• Bottoming chamfer allows threading to the full depth of blind holes
• M3x0.50 metric coarse thread form with right-hand direction
• 6H class of fit with D3 thread limit for consistent tolerance control
• 3 straight flutes for straightforward chip management in through and blind hole applications
• High-speed steel construction provides durability across ferrous and non-ferrous workpieces
• Bright, uncoated finish suitable for general-purpose tapping applications

Compatibility

Designed as a general-purpose M3x0.50 metric coarse bottoming tap compatible with standard tap holders, T-handle wrenches, and machine tapping chucks sized for small-diameter taps.

Installation Notes

This tap is installed and operated by qualified machinists using appropriate tapping fluids, T-handle tap wrenches, or low-speed tapping machines. Always secure the workpiece before tapping and ensure the hole is drilled to the correct tap drill diameter for an M3x0.50 thread before starting. Back off periodically during manual tapping to break chips and prevent tap breakage. Inspect the tap for wear or damage before each use, as broken small-diameter taps can be difficult to extract from a workpiece.
