Osg 1727101 Spiral Point Tap 6-32 Unc Plug H4 Hss

Product Description

The OSG 1727101 is a spiral point plug tap designed for cutting internal 6-32 UNC threads in a range of ferrous materials. Manufactured from vanadium high-speed steel (HSS-E) and finished with a steam oxide coating, this tap offers improved lubricity and corrosion resistance during threading operations. It features a plug chamfer, H4 thread limit, and a right-hand thread direction. With an overall length of 2 inches and a thread length of 0.375 inches, the 1727101 is built to the tolerances required for 2B class of fit applications. Licensed HVAC technicians, machinists, and maintenance tradespeople commonly use this tap for production and repair threading work.

This tap is suited for threading operations in low-carbon steel, medium-carbon steel, hardened steel, and stainless steel. The spiral point design pushes chips forward ahead of the cutting edge, making it effective in through-hole applications where chip evacuation is critical. It is a practical choice for production environments and field repair situations where consistent thread quality in the 6-32 UNC size is required.

Key Features

• 6-32 UNC thread size with 2B class of fit tolerance
• H4 thread limit for controlled thread sizing
• Vanadium high-speed steel (HSS-E) construction for durability in ferrous materials
• Steam oxide coating improves lubricity and reduces friction during cutting
• Plug chamfer for standard through-hole and blind-hole entry
• Right-hand thread direction, no coolant-through requirement
• Spiral point geometry pushes chips forward for efficient chip evacuation

Compatibility

Designed for threading 6-32 UNC through-holes in low-carbon steel, medium-carbon steel, hardened steel, and stainless steel workpieces. Compatible with standard tap handles and machine tap holders accepting a 0.141-inch shank diameter.

Installation Notes

This tap should be installed by qualified machinists or maintenance tradespeople familiar with threading operations and cutting tool safety. Always ensure the workpiece is securely fixtured and the spindle or tap driver is properly aligned before beginning the threading operation. Use an appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Inspect the tap for wear or chipping before each use and replace if damage is observed.
