Osg 2819108 Spiral Point Tap 10-32 Unf Ticn 3 Flute

Product Description

The OSG 2819108 is a spiral point tap designed for through-hole threading in demanding metalworking applications. Built from HSS-E Vanadium high-speed steel with a TiCN coating, this tap delivers extended tool life when cutting through steel, stainless steel, cast iron, and other hard materials. The plug chamfer configuration aids thread entry and chip control, while the three-flute spiral point geometry pushes chips forward through the hole rather than packing them in the flute. With an overall length of 2.37 inches and a thread length of 0.492 inches, this tap is suited for precision threading work in both production and maintenance environments.

The OSG 2819108 cuts a 10-32 UNF right-hand thread and is intended for through-hole applications. It is well suited for machine shops, tool rooms, maintenance facilities, and manufacturing lines working with ferrous and hard materials. The H11 thread limit provides a standard tolerance class appropriate for general-purpose UNF threading. This tap is run on drill presses, CNC machining centers, and tapping machines where controlled feed rates are practical. The Series 280 classification places it within a recognized OSG product family for spiral point tooling.

Key Features

• TiCN coating improves hardness and lubricity for longer tool life in hard and abrasive materials
• HSS-E Vanadium substrate provides added toughness compared to standard M2 high-speed steel
• Spiral point geometry pushes chips forward, reducing chip clogging in through-hole operations
• Plug chamfer allows progressive thread engagement and easier tap entry
• H11 thread limit suits standard tolerance through-hole threading in UNF applications
• Three-flute design balances chip clearance and cutting stability

Compatibility

Designed for through-hole threading of 10-32 UNF right-hand threads in steel, stainless steel, cast iron, and hard materials using standard tapping equipment.

Installation Notes

This tap should be installed and operated by a qualified machinist or tooling technician. Ensure the workpiece is securely fixtured and the tapping machine spindle is properly aligned before beginning the thread cutting cycle. Use an appropriate cutting fluid for the material being tapped to prevent premature tool wear. Do not force the tap if resistance is encountered; back off to clear chips before continuing.
