Osg 2512401 Spiral Point Tap 6-32 Unc 2 Flute Hss

Product Description

The OSG 2512401 is a spiral point tap designed for threading 6-32 UNC holes in a wide range of metals. It features a plug chamfer, 2-flute geometry, and a steam oxide coating over vanadium high-speed steel construction. The spiral point design pushes chips forward ahead of the cut, making it well suited for through-hole tapping operations. With an H2 thread limit and a 2B class of fit, this tap produces threads within standard tolerance for general mechanical assembly. Overall length is 2.25 inches with a thread length of 0.37 inches. Licensed machinists and tool-and-die professionals are the primary installers.

This tap is used in machine shop, production, and maintenance environments where 6-32 UNC threads are required in through holes. It handles a broad range of workpiece materials including aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, stainless steel, die steel, and cast iron. The oxide finish provides light lubricity and corrosion resistance during storage and cutting. It is suited for CNC tapping, drill press, and hand-tapping applications where forward chip ejection is an advantage.

Key Features

• Spiral point geometry pushes chips forward, ideal for through-hole tapping
• Steam oxide coating provides light lubricity and surface protection
• Vanadium high-speed steel (HSS-E) construction for wear resistance across hard and abrasive materials
• H2 thread limit with 2B class of fit for standard-tolerance threaded assemblies
• Right-hand cut, 2-flute design for efficient material removal
• Compatible with a wide material range including stainless steel, cast iron, and alloy steel

Compatibility

Designed for through-hole tapping of 6-32 UNC threads in aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, stainless steel, die steel, and cast iron workpieces.

Installation Notes

Install in a tap holder, CNC spindle, or tapping head rated for the shank diameter of 0.141 inches. Power down and secure the workpiece before beginning any tapping operation. Use an appropriate cutting fluid or tapping compound for the workpiece material, particularly when tapping stainless steel or hardened alloy steel. Inspect the tap for chipping or wear before each use and replace at the first sign of thread-form degradation.
