Hertel K020169AS Straight Flute Tap M6x1.00 Metric Coarse Hss

Product Description

The HERTEL K020169AS is a straight flute tap designed for cutting M6x1.00 metric coarse internal threads in a variety of ferrous and non-ferrous materials. Built from high-speed steel with a bright, uncoated finish, this tap delivers reliable performance in general-purpose threading applications. The plug chamfer style provides a moderate lead-in, making it well-suited for through-holes and blind holes with adequate clearance. With 4 flutes and a right-hand thread direction, it generates clean, accurate threads when used at appropriate speeds and with proper cutting fluid. Overall length is 2.5 inches, thread length is 1 inch, and shank diameter is 0.255 inches.

This tap is used in machine shop, maintenance, and field-repair applications where M6x1.00 metric coarse threads are required. It is compatible with standard tap handles, T-handle wrenches, and CNC or manual tapping heads. Typical applications include tapping threaded holes in steel, aluminum, cast iron, and similar materials during equipment fabrication, repair, or assembly work. The straight flute geometry is best suited for short-chipping materials where chip evacuation through the flutes is manageable.

Key Features

• M6x1.00 metric coarse thread profile with right-hand thread direction
• 4 straight flutes for clean thread cutting in short-chipping materials
• Plug chamfer provides moderate lead-in, suitable for through-holes and deeper blind holes
• High-speed steel construction for durability across general-purpose threading tasks
• Bright, uncoated finish — no coating to interfere with tight tolerances
• D3 thread limit for standard-tolerance metric thread fits

Compatibility

Designed as a standard replacement or stocking tap for M6x1.00 metric coarse threading operations using conventional tap handles, tapping heads, or CNC tapping attachments with appropriate collets or tap holders.

Installation Notes

Tapping operations should be performed by a machinist or qualified technician familiar with cutting tool speeds, feeds, and lubrication requirements. Always use a suitable cutting fluid or tapping compound to extend tool life and improve thread quality. Secure the workpiece firmly before beginning and ensure the tap is properly aligned to avoid tap breakage. Follow applicable shop safety procedures when operating any rotating cutting tool.
