Accupro T2690565 Spiral Point Tap 1/2-13 4 Flute Hss

Product Description

The ACCUPRO T2690565 is a spiral point tap designed for threading 1/2-13 UNC holes in production and job-shop environments. Built from 3% Vanadium High Speed Steel with a bright finish, it delivers solid wear resistance and edge retention when threading steels, cast iron, and titanium. The plug chamfer distributes cutting forces across the lead threads for smooth entry in through-hole applications. With a 4-flute spiral point geometry, chips are pushed forward ahead of the tap rather than packed into the flutes, reducing the risk of tap breakage during high-volume threading operations. Overall length is 3.38 inches and thread length is 29 millimeters.

This tap is suited for through-hole threading in machining centers, drill presses, and tapping machines in both production and maintenance settings. The H5 thread limit and 2B class of fit make it appropriate for standard unified fastener applications where close tolerances are required. Right-hand thread direction is standard for conventional 1/2-13 UNC fastener assemblies. Machinists, tool-and-die makers, and maintenance technicians working with titanium, steel, or similar materials will find this tap a dependable choice for consistent thread quality.

Key Features

• Spiral point geometry pushes chips forward, ideal for through-hole threading
• 3% Vanadium High Speed Steel construction for improved wear resistance and edge retention
• H5 thread limit with 2B class of fit for standard unified fastener tolerances
• Plug chamfer provides gradual cutting action and smooth thread entry
• Bright finish suitable for general-purpose threading without additional coating
• Rated for titanium material application, suitable for challenging workpiece materials

Compatibility

Designed as a standard replacement or production tap for 1/2-13 UNC through-hole threading applications requiring H5 thread limit and 2B class of fit.

Installation Notes

This tap should be installed in a proper tap holder or floating tap collet to allow axial float and prevent thread distortion. Apply appropriate cutting fluid or tapping oil before use, particularly when threading titanium or high-strength steels. Ensure the spindle speed and feed rate are matched to the workpiece material per standard machining practice. Inspect the tap for chipping or wear before each use and replace when thread quality degrades.
