Osg 1721802 Spiral Point Tap 10-32 Unf Hss

Product Description

The OSG 1721802 is a spiral point tap designed for cutting 10-32 UNF threads in through-hole applications. It features a plug chamfer style with 2 flutes and is manufactured from high-speed steel with an elektraLUBE coating that reduces friction and extends tool life. The thread limit is H7, providing controlled tolerance for consistent fit. With a thread length of 0.875 inches, this tap suits standard machine tapping operations in a variety of ferrous and non-ferrous materials. It is used by machinists, maintenance technicians, and trade professionals in production and repair environments.

This tap is suited for tapping 10-32 UNF threads in materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. The right-hand thread direction and plug chamfer make it appropriate for through-hole production tapping on manual machines, CNC machining centers, and drill presses where chip pushing ahead of the tap is acceptable. The elektraLUBE coating supports dry or minimal-lubrication cutting, making it practical in shops where coolant-through tooling is not required.

Key Features

• 10-32 UNF thread form with H7 thread limit for controlled tolerance
• Plug chamfer style pushes chips forward, ideal for through-hole tapping
• 2-flute spiral point design for efficient chip evacuation in production cuts
• High-speed steel construction for durability across a wide range of materials
• elektraLUBE coating reduces friction and supports dry or low-lubrication operation
• Right-hand thread direction, no coolant-through requirement

Compatibility

Designed for tapping 10-32 UNF right-hand threads in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces.

Installation Notes

Tapping operations should be performed by qualified machinists following standard machine shop practices. Secure the workpiece and ensure the tap is properly aligned to the drilled pilot hole before engagement to avoid tap breakage. For manual tapping, use a calibrated tap wrench and apply cutting fluid appropriate to the workpiece material even when using an elektraLUBE-coated tool in demanding materials. Inspect the tap for wear or chipping between operations, especially when working in hardened steel.
