Regal Cutting Tools 024278AS Spiral Point Tap M5x0.8

Product Description

The REGAL CUTTING TOOLS 024278AS is a spiral point tap designed for through-hole threading in metalworking and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap cuts M5x0.8 metric threads in right-hand orientation. The spiral point geometry pushes chips forward ahead of the cutting zone, making it well suited for through-hole work where chip evacuation is critical. It features a plug chamfer and D11 thread limit, with an overall length of 2.375 inches and a thread length of 0.875 inches. This is a general-purpose tool intended for machinists, tool-and-die shops, and maintenance professionals.

This tap is used in through-hole threading operations on ferrous and non-ferrous materials in general-purpose machining environments. The M5x0.8 metric thread size is common in automotive, industrial equipment, and fixture assembly work. With a 2-flute design and spiral point style, it is optimized for production and manual tapping in materials where chip flow management matters. The plug chamfer provides a moderate lead-in that works in most standard through-hole applications without the aggressive entry of a bottoming tap.

Key Features

• Spiral point geometry pushes chips forward for clean through-hole threading
• M5x0.8 metric thread size with 0.8 mm pitch and right-hand thread direction
• D11 thread limit class of fit for general-purpose metric threading tolerances
• High-speed steel construction for durability across general-purpose materials
• Bright, uncoated finish suitable for use with standard cutting fluids
• 2-flute design with plug chamfer for controlled lead-in and moderate starting ease

Compatibility

Designed as a general-purpose spiral point tap for through-hole M5x0.8 metric threading operations. Fits standard tap holders and tapping heads accepting a 0.194-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling professional. Secure the workpiece fully before tapping and ensure the tap is aligned perpendicular to the hole to prevent breakage. Use an appropriate cutting fluid for the material being tapped. Always back the tap out periodically to clear chips and reduce the risk of tap binding or fracture.
