Value Collection MSC-04997490 M8x1.25 Spiral Point Tap

Product Description

The VALUE COLLECTION MSC-04997490 is a spiral point tap designed for cutting M8x1.25 metric coarse threads in through-hole applications. Made from high speed steel with a bright uncoated finish, it features a plug chamfer and a 2-flute spiral point geometry that pushes chips forward ahead of the cutting zone, reducing clogging and supporting cleaner thread formation at production speeds. The 6H class of fit delivers standard tolerance threading suitable for the majority of general-purpose metric fastener applications. Thread length is 1.125 inches. This tap is a common choice for machine tapping operations across a wide range of metalworking trades.

This tap is suited for through-hole threading in metals including mild steel, aluminum, and similar machinable materials where chip evacuation is the primary concern. The plug chamfer provides a moderate lead-in and works well in both CNC machining centers and manual tapping setups. Right-hand thread direction is standard. It is appropriate for job shops, maintenance and repair operations, and production environments where M8x1.25 threads are frequently cut.

Key Features

• M8x1.25 metric coarse thread form, right-hand direction
• Spiral point geometry pushes chips forward, ideal for through-hole tapping
• 2-flute design suited for moderate chip load and general-purpose use
• Plug chamfer provides gradual lead-in for machine or hand tapping
• 6H class of fit for standard metric fastener tolerance
• High speed steel construction with bright uncoated finish

Compatibility

Designed as a general-purpose metric spiral point tap for through-hole M8x1.25 applications; fits standard tap holders and collets sized for M8 taps used in machining centers, drill presses, and tapping arms.

Installation Notes

Spiral point taps are installed by machinists and toolroom professionals using rigid or floating tap holders in CNC machines, tapping arms, or drill presses. Ensure the workpiece is clamped securely and the tap is aligned axially with the pre-drilled pilot hole before engaging the spindle. Use appropriate tapping fluid or cutting oil for the workpiece material to extend tool life and improve thread quality. Do not reverse the tap under power without confirming the machine spindle is programmed for a controlled reverse cycle.
