Osg 1101500905 Spiral Point Tap 8-32 Unc Tin Hss

Product Description

The OSG 1101500905 is a spiral point plug tap designed for cutting 8-32 UNC threads in a wide range of materials. Built from vanadium high-speed steel and finished with a titanium nitride (TiN) coating, this tap delivers extended tool life and reduced friction compared to uncoated HSS alternatives. It features 3 flutes, a right-hand thread direction, and an H3 thread limit with a 2B class of fit, making it suitable for general-purpose tapping applications where precise thread tolerance is required. Machinists and maintenance technicians rely on this tap for production and repair work across ferrous and non-ferrous base materials.

This tap is suited for use in machine tapping applications in manufacturing, fabrication, and maintenance environments. The spiral point geometry pushes chips forward ahead of the tap, making it particularly effective in through-hole applications. Compatible materials include aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, hardened steel, cast iron, high-nickel alloys, and titanium. It is part of the OSG Series 11015 product line.

Key Features

• 8-32 UNC thread size with right-hand thread direction and 2B class of fit
• H3 thread limit for consistent tolerance control in production tapping
• TiN coating reduces friction and extends tool life over uncoated HSS
• Vanadium high-speed steel construction for strength and wear resistance
• Spiral point geometry pushes chips forward, ideal for through-hole tapping
• Rated for use in a broad range of materials including stainless steel, titanium, and high-nickel alloys

Compatibility

Designed for through-hole tapping of 8-32 UNC threads across materials including aluminum, carbon steels, alloy steel, die steel, stainless steel, hardened steel, cast iron, high-nickel alloys, and titanium.

Installation Notes

This tap should be installed in a machine tapping setup or hand tap wrench by a qualified machinist or maintenance technician. Ensure the workpiece is securely fixtured and the tap is properly aligned before engaging. Apply appropriate cutting fluid for the base material to reduce heat buildup and extend tap life. Inspect the tap for wear or chipping before each use and replace if thread quality degrades.
