Sandvik Coromant 6967151 Spiral Point Tap M8x1.25 3 Flute

Product Description

The SANDVIK COROMANT 6967151 is a spiral point tap in the CoroTap 200 series, designed for cutting internal metric threads in production and maintenance environments. It produces M8x1.25 threads with a plug chamfer and a 6H class of fit, making it suitable for standard tolerance threading applications. Built from high-speed steel with a bright uncoated finish, it operates with right-hand thread direction and features 3 flutes for efficient chip evacuation forward through the hole. With an overall length of 92.89 mm and a thread length of 18.90 mm, this tap is used by machinists and maintenance technicians working in metal fabrication, production shops, and industrial maintenance settings.

This tap is rated for use in cast iron, high-temperature alloys, non-ferrous metals, and steel, covering a broad range of common workpiece materials. The plug chamfer style makes it well suited for through-hole threading applications where a gradual thread lead-in is acceptable. It is a single-piece unit sold individually, appropriate for use in both CNC tapping and hand-tapping operations where controlled feed and speed can be maintained. The CoroTap 200 series is engineered for consistent performance in medium to high production volume scenarios.

Key Features

• M8x1.25 metric thread size with 6H class of fit for standard tolerance applications
• Plug chamfer for gradual thread engagement, optimized for through-hole tapping
• 3-flute spiral point design pushes chips forward to clear the cutting zone
• High-speed steel construction provides durability across steel, cast iron, non-ferrous metal, and high-temperature alloy workpieces
• Bright uncoated finish; no coolant-through feature, suitable for flooded or external coolant delivery
• Right-hand thread direction; 8.08 mm shank diameter for standard toolholder compatibility

Compatibility

Designed for use in standard toolholders accepting an 8.08 mm shank diameter. Rated for threading cast iron, high-temperature alloys, non-ferrous metals, and steel workpieces. Part of the SANDVIK COROMANT CoroTap 200 series.

Installation Notes

This tap should be installed by a qualified machinist familiar with tapping feeds, speeds, and torque requirements for the target workpiece material. Always ensure the machine spindle is fully stopped and locked out before changing tooling. Use appropriate cutting fluid or coolant applied externally when tapping steel and cast iron to extend tool life and maintain thread quality. Verify shank seating and toolholder clamping before initiating the tapping cycle.
