Osg 1101501905 Spiral Point Tap 10-32 Unf 3 Flutes Tin

Product Description

The OSG 1101501905 is a spiral point plug tap designed for cutting internal 10-32 UNF threads in a wide range of ferrous and non-ferrous materials. Built from vanadium high speed steel and finished with a titanium nitride (TiN) coating, this tap delivers extended tool life and reduced cutting friction compared to uncoated alternatives. The three-flute spiral point geometry pushes chips forward ahead of the cutting edge, making it well suited for through-hole tapping operations. With an H7 thread limit, it holds tight tolerance control for precision threaded assemblies. At 2.374 inches overall length and a 0.194-inch shank diameter, the tap fits standard tap holders and chuck-style tap drivers.

This tap is used in machining, maintenance, and fabrication environments wherever 10-32 UNF through-hole threads are required. Typical applications include work on aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, hardened steel, cast iron, high-nickel alloy, and titanium workpieces. It is appropriate for both CNC tapping centers and manual drill press setups. Machinists, tool-and-die makers, and maintenance technicians commonly specify this tap for production and repair threading tasks. Coolant-through capability is not included in this configuration.

Key Features

• Spiral point geometry pushes chips forward for clean through-hole tapping
• TiN coating reduces friction and extends cutting life
• Vanadium high speed steel construction handles a broad range of workpiece materials
• H7 thread limit provides consistent, close-tolerance thread fit
• Right-hand thread direction for standard tapping operations
• 3-flute design for balanced cutting load

Compatibility

Designed for cutting 10-32 UNF internal threads in through-hole applications across aluminum, steel alloys, stainless steel, cast iron, high-nickel alloy, and titanium workpieces. OSG Series 11015.

Installation Notes

Install in a tap holder or chuck driver sized for a 0.194-inch shank before use. Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole to prevent tap breakage. Apply appropriate cutting fluid for the workpiece material, particularly when working with stainless steel or high-nickel alloys. Follow standard shop safety procedures when operating tapping equipment.
