Cle-line C62179 M5x0.80 Spiral Point Tap 2 Flute Plug Hss

Product Description

The CLE-LINE C62179 is a spiral point plug tap designed for through-hole threading in metric coarse applications. Built from high-speed steel with a bright uncoated finish, it cuts an M5x0.80 thread profile with a 2-flute, right-hand configuration. The spiral point geometry pushes chips forward through the hole, making it well suited for production tapping in through-hole setups where chip evacuation is a priority. Overall length is 2.375 inches with a thread length of 0.875 inches and a shank diameter of 0.1941 inches. The D4 thread limit designation ensures the tap holds tolerance for standard metric fastener fits.

This tap is intended for through-hole threading operations in materials including cast iron, non-ferrous aluminum, and steel. It is commonly used in machine tapping and hand tapping setups where consistent metric coarse threads are required. The plug chamfer provides a gradual cutting lead that suits general-purpose through-hole work across a range of production and maintenance applications. Machinists, tool and die technicians, and maintenance mechanics will find this tap appropriate for both CNC and manual tapping operations.

Key Features

• High-speed steel construction for durability across cast iron, aluminum, and steel
• Plug chamfer for gradual cutting entry in through-hole applications
• D4 thread limit for consistent tolerance control on metric fits
• Bright uncoated finish suitable for use with standard cutting fluids

Compatibility

Designed for through-hole threading in cast iron, non-ferrous aluminum, and steel workpieces requiring an M5x0.80 metric coarse thread. Part of the CLE-LINE Series 0411M spiral point tap line.

Installation Notes

Installation is performed by machinists or maintenance technicians using a tap wrench, tapping head, or CNC tapping attachment. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Secure the workpiece firmly before tapping and ensure the tap enters the hole straight to avoid thread damage or tap breakage. Replace the tap if cutting resistance increases significantly or thread quality degrades.
