Hertel K020153AS Straight Flute Tap M5x0.80 Metric Coarse

Product Description

The HERTEL K020153AS is a straight flute plug tap designed for cutting M5x0.80 metric coarse internal threads in through-holes and shallow blind holes. Manufactured from high-speed steel with a bright uncoated finish, it delivers reliable thread-cutting performance across a range of common workpiece materials. The plug chamfer — typically 3 to 5 threads of lead — provides a starting action suited to general-purpose tapping on manual machines, drill presses, and tapping arms. With 4 flutes and a right-hand thread direction, this tap produces clean, accurate threads at standard D2 tolerance. It weighs 0.2 pounds and has an overall length of 2.375 inches, making it easy to handle in tight setups.

This tap is suited for machine shops, maintenance and repair operations, and production environments where M5x0.80 metric coarse threads are required. The straight flute geometry works best in shorter-chipping materials such as cast iron, brass, aluminum, and free-machining steels. The plug style makes it appropriate as a general starter tap or as the only tap in a through-hole application. It is used by machinists, tool-and-die technicians, and maintenance mechanics across industrial, automotive, and general fabrication settings.

Key Features

• M5x0.80 metric coarse thread form for standard metric fastener compatibility
• Plug chamfer with 3 to 5 thread lead for general-purpose starting in through-holes
• 4 straight flutes optimized for shorter-chipping materials
• High-speed steel construction provides durability in moderate-speed hand and machine tapping
• D2 thread limit for standard tolerance class fits
• Bright uncoated finish — no coating buildup to affect thread tolerance

Compatibility

Designed as a standard straight flute plug tap for M5x0.80 metric coarse threads; fits standard tap holders, tapping heads, and manual tap wrenches accepting a 0.194-inch shank diameter.

Installation Notes

This tap is installed and operated by machinists and maintenance technicians using standard tap wrenches, tapping arms, or CNC/manual machine tool holders. Always ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole before starting. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Do not force the tap through a hole that is undersized — verify the correct M5x0.80 tap drill diameter before beginning.
