Accupro T2680506 Spiral Point Tap M12x1.75 3 Flute Plug

Product Description

The ACCUPRO T2680506 is a spiral point tap designed for cutting M12x1.75 metric threads in through-hole applications. Built from vanadium high-speed steel, the tap delivers reliable hardness and wear resistance across a range of production environments. It features a plug chamfer for standard starting conditions and a right-hand thread direction. With a D6 thread limit and a 6H class of fit, it holds tight tolerances suitable for general-purpose metric threading. The bright, uncoated finish makes it well suited for use with cutting fluids. Licensed machinists and toolroom mechanics install this tap in both manual and CNC tapping operations.

This tap is engineered for threading aluminum workpieces, where its three-flute spiral point geometry pushes chips forward and out of through-holes to prevent clogging and tap breakage. It is appropriate for residential shop, light industrial, and production machining environments. The M12x1.75 thread form is common in automotive, mechanical assembly, and general fabrication work where metric fastener patterns are specified. Its 9.32 mm shank diameter fits standard tap holders and quick-change tapping chucks used in vertical machining centers and drill presses.

Key Features

• M12x1.75 metric thread form with 6H class of fit for standard tolerance applications
• Vanadium high-speed steel construction for improved wear resistance over standard HSS
• Three-flute spiral point geometry pushes chips forward in through-hole tapping
• Plug chamfer provides a standard lead-in for most production tapping setups
• D6 thread limit maintains consistent fit across production runs
• Bright uncoated finish compatible with water-soluble and oil-based cutting fluids

Compatibility

Designed as an OEM-style replacement tap for M12x1.75 metric through-hole applications using standard tap holders and quick-change tapping chuck systems.

Installation Notes

This tap is installed by machinists and toolroom professionals using a properly sized tap holder or quick-change chuck. Always ensure the workpiece is securely clamped and the spindle is aligned with the hole axis before starting. Apply an appropriate cutting fluid for aluminum to reduce heat and extend tool life. Do not force the tap if resistance increases unexpectedly — back off to clear chips before continuing.
