Osg 1207400 Spiral Point Tap 6-32 Unc Hss Bright

Product Description

The OSG 1207400 is a spiral point tap designed for cutting internal threads in a wide range of ferrous and non-ferrous materials. Built from high-speed steel with a bright finish, this plug-chamfer tap drives chips forward ahead of the cutting zone, making it well suited for through-hole tapping operations. It produces a 6-32 UNC thread form to a 3B class of fit with an H2 thread limit, giving machinists and maintenance technicians the dimensional control needed for standard fastener applications. At 2 inches overall length with an 11/16-inch thread length, it fits standard tap holders and machine spindles used in production and repair environments.

This tap is appropriate for through-hole tapping in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. It is a right-hand tap intended for use in CNC machining centers, drill presses, and hand-tapping setups where the 6-32 UNC thread form is required. The 2-flute configuration provides chip clearance suited to general-purpose through-hole work across both production and maintenance applications.

Key Features

• 6-32 UNC thread form with 3B class of fit and H2 thread limit for standard fastener accuracy
• Spiral point geometry pushes chips forward, keeping the flutes clear during through-hole tapping
• High-speed steel construction supports use in a broad range of workpiece materials including hardened steel
• Bright finish with no coating, providing a cost-effective option for general-purpose tapping
• Right-hand cut, 2-flute design compatible with standard tap holders and machine spindles
• Compact 2-inch overall length suits confined fixture setups and standard tapping chucks

Compatibility

Designed for through-hole tapping applications requiring a 6-32 UNC internal thread in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces.

Installation Notes

This tap should be installed in a proper tap holder or floating tap chuck to allow axial float and reduce the risk of breakage. Always apply appropriate cutting fluid for the workpiece material before and during tapping. Ensure the spindle and workpiece are properly aligned before engaging the tap. Replace worn taps promptly, as a dull cutting edge significantly increases the risk of tap breakage in small-diameter threads.
