Regal Cutting Tools 027711AS74 Spiral Point Tap M2x.4

Product Description

The REGAL CUTTING TOOLS 027711AS74 is a spiral point tap designed for cutting metric internal threads in through-hole applications. Built from high speed steel (HSS) with a chrome finish, this tap features a plug chamfer and a D3 thread limit, making it well suited for general-purpose tapping in a range of metalworking and machining operations. The M2x.4 thread size and 6H class of fit meet standard metric tolerance requirements. With an overall length of 1.75 inches and a thread length of 0.4375 inches, this tap is sized for compact work envelopes where precision thread formation is critical.

This tap is intended for use in production machining, toolroom work, and maintenance repair operations where metric threaded holes are required. The two-flute spiral point design pushes chips ahead of the cutting action, making it effective in through-hole tapping on ferrous and non-ferrous materials. Right-hand thread direction is standard for conventional metric fastener applications. Licensed machinists, tool and die makers, and maintenance technicians are the typical users.

Key Features

• M2x.4 metric thread size with 6H class of fit for standard metric tolerance applications
• Spiral point geometry pushes chips forward, reducing chip packing in through-hole work
• Plug chamfer provides gradual thread engagement for reliable starting in pre-drilled holes
• High speed steel construction offers durability across common workpiece materials
• Chrome finish helps resist corrosion and reduces friction during the cutting process
• D3 thread limit supports consistent fit with mating metric fasteners

Compatibility

Designed as an OEM-style replacement or direct-use spiral point tap for through-hole metric tapping applications requiring an M2x.4 thread profile and 6H class of fit.

Installation Notes

This tap is installed by machinists and toolroom professionals using a tap wrench, tapping head, or CNC machine spindle. Always ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct diameter for an M2x.4 thread before tapping. Use appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. Inspect the tap for wear or damage before each use and replace if chipping or dullness is observed.
