Osg 1702701 Spiral Point Tap M10x1.25 Metric Fine Plug

Product Description

The OSG 1702701 is a spiral point plug tap designed for threading M10x1.25 metric fine holes in demanding materials. Manufactured from powdered metal and finished with a steam oxide coating, it delivers consistent performance in applications where standard high-speed steel falls short. The spiral point geometry pushes chips forward through the hole, keeping the flutes clear during through-hole tapping operations. With 3 flutes and a D5 thread limit, this tap is suited for production environments where tight tolerances and repeatable thread quality are required. Overall length is 74.6 mm and thread length is 1.25 inches.

This tap is intended for through-hole tapping in hard-to-machine materials including hardened steel, stainless steel, high-nickel alloy, titanium, alloy steel, and die steel. The plug chamfer provides a gradual lead-in, making it a practical choice for both CNC machining centers and manual tapping operations in job shop and production settings. Machinists and toolroom technicians working on aerospace, die, and precision manufacturing applications will find this OSG Series 344 tap well-suited to their requirements.

Key Features

• Spiral point geometry pushes chips forward for clean through-hole tapping
• Powdered metal construction for improved wear resistance in tough alloys
• Steam oxide coating reduces friction and provides corrosion resistance
• Plug chamfer for gradual thread engagement and reduced torque on entry
• D5 thread limit ensures controlled tolerance fit for metric fine threads
• Right-hand thread direction, non-coolant-through design

Compatibility

Designed for tapping M10x1.25 metric fine through-holes in hardened steel, stainless steel, high-nickel alloy, titanium, alloy steel, and die steel workpieces.

Installation Notes

This tap should be installed and operated by qualified machinists familiar with threading operations. Always ensure the workpiece and machine spindle are properly secured before tapping. Use an appropriate cutting fluid or tapping compound recommended for the workpiece material to extend tool life and maintain thread quality. Inspect the tap for wear or chipping before each use and replace if the cutting edges show damage.
