Accupro T2667364 Spiral Flute Tap M8 X 1.25 3 Flute

Product Description

The ACCUPRO T2667364 is a spiral flute tap designed for threading M8 x 1.25 holes in demanding materials including titanium. It is manufactured from 3% vanadium high speed steel and features a modified bottoming chamfer, making it well suited for threading to the bottom of blind holes where standard taps cannot reach. With 3 right-hand flutes in a slow helix configuration at 15 degrees, the tool efficiently evacuates chips upward during the tapping operation. Overall length is 2.13 inches. This tap is used by machinists, tool-and-die makers, and maintenance technicians in metal fabrication, aerospace, and general manufacturing environments.

The T2667364 is intended for use in materials that demand tougher tooling, with titanium listed as the primary material application. The modified bottoming chamfer allows threading closer to the base of a blind hole than a plug or taper chamfer would permit. The D4 thread limit provides a slightly oversized thread tolerance to account for material springback in tougher alloys. This tap is suited for use in CNC machining centers, manual mills, or drill press tapping setups where right-hand M8 x 1.25 threads are required.

Key Features

• M8 x 1.25 thread size for standard metric fastener applications
• Modified bottoming chamfer enables threading near the base of blind holes
• 3% vanadium high speed steel construction for increased wear resistance in difficult materials
• D4 thread limit accommodates material springback in harder alloys including titanium
• Slow 15-degree right-hand spiral flute promotes controlled chip evacuation
• Bright/uncoated finish suitable for use with cutting fluids and oils

Compatibility

Designed as an OEM-style replacement or direct-use spiral flute tap for M8 x 1.25 right-hand thread applications in metalworking operations, particularly where titanium or similarly demanding workpiece materials are involved.

Installation Notes

This tap is installed and operated by machinists or maintenance technicians familiar with threading procedures. Always secure the workpiece and use the appropriate tapping fluid or cutting oil, especially when threading titanium. Ensure the tap is properly aligned with the pilot hole before applying torque to avoid breakage or thread damage. Follow applicable shop safety standards and machinery guarding requirements during operation.
