Osg 2817601 Spiral Point Tap 6-32 Unc Plug Hss

Product Description

The OSG 2817601 is a spiral point plug tap designed for cutting 6-32 UNC right-hand internal threads in a wide range of 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 2 flutes, a plug chamfer for gradual thread engagement, and an H7 thread limit for controlled oversize tolerance. With an overall length of 2 inches and a thread length of 0.6875 inches, it is suited for standard machine tapping applications in production and maintenance environments. Licensed machinists, tool and die makers, and maintenance technicians are the typical users.

This tap is built for threading applications across a broad spectrum of ferrous and non-ferrous materials. It performs in aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and cast iron. The plug chamfer makes it appropriate for through-hole tapping where chip evacuation is assisted by the spiral point geometry pushing chips ahead of the tap. It fits standard tapping chucks and CNC rigid tapping setups that accept a 0.141-inch shank diameter. It is part of OSG Series 280 and is sold individually.

Key Features

• 6-32 UNC right-hand thread form with H7 oversize tolerance for consistent fit
• Vanadium high speed steel (HSS-E) construction for extended tool life in tough materials
• Steam oxide coating reduces friction and improves chip flow during cutting
• Spiral point geometry pushes chips forward, suited for through-hole applications
• Plug chamfer provides gradual thread engagement and reduced entry force
• Coolant-through: No — standard flood or manual lubrication applies

Compatibility

Designed as a direct-fit replacement or standard tooling option for any application requiring a 6-32 UNC plug tap with H7 thread limit in a 0.141-inch shank diameter, compatible with standard tapping chucks and CNC rigid tapping holders accepting that shank size.

Installation Notes

This tap is installed and operated by machinists, tool and die professionals, or maintenance technicians using standard drill presses, CNC machining centers, or tapping arms. Always ensure the pilot hole is drilled to the correct tap drill diameter for 6-32 UNC prior to tapping. Apply appropriate cutting fluid or tapping oil for the workpiece material to extend tap life and improve thread quality. Back the tap out periodically in manual applications to break and clear chips, particularly in deeper holes or tougher materials.
