Regal Cutting Tools 024276AS Spiral Point Tap M4x0.7 Hss

Product Description

The REGAL CUTTING TOOLS 024276AS is a spiral point tap designed for through-hole threading in metric applications. It cuts an M4x0.7 thread profile using a 2-flute, plug chamfer geometry that pushes chips forward ahead of the cutting zone, keeping the flutes clear during machine tapping operations. The tap is manufactured from high-speed steel (HSS) with a bright, uncoated finish and carries a D11 thread limit for standard general-purpose tolerances. Overall length is 2.125 inches with a thread length of 0.75 inches. Licensed machinists, tool and die makers, and maintenance technicians install this tap in production and maintenance settings.

This tap is suited for through-hole threading operations in ferrous and non-ferrous metals where chip evacuation is a priority. The spiral point style is well matched to CNC and manual machine tapping in general-purpose manufacturing, fabrication shops, and maintenance-repair-overhaul environments. Right-hand thread direction and a plug chamfer entry make it compatible with standard tapping heads and floating tap holders. The M4x0.7 metric thread size is common in light-duty fastener applications across automotive, electronics, and general mechanical assemblies.

Key Features

• Spiral point geometry pushes chips forward during through-hole tapping, reducing chip clogging
• M4x0.7 metric thread profile with plug chamfer for guided thread entry
• High-speed steel construction provides good wear resistance in general-purpose materials
• D11 thread limit delivers consistent tolerance control for standard metric fits
• Right-hand thread direction compatible with standard tapping equipment
• Bright, uncoated finish suitable for use with cutting fluids in general-purpose applications

Compatibility

Designed for general-purpose through-hole threading in applications requiring an M4x0.7 metric right-hand thread. Intended for use with standard tapping heads, floating holders, and rigid tapping setups in CNC or manual machine tools that accept a 0.168-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or technician familiar with tapping operations and cutting tool safety. Ensure the workpiece is securely fixtured and the machine spindle is properly aligned before starting the tap. Use an appropriate cutting fluid or tapping compound to extend tool life and improve thread quality. Do not reverse the tap under power without confirming the machine is set for proper back-out to avoid tap breakage.
