Osg 1651501108 Spiral Point Tap 10-24 Unc Ticn Plug

Product Description

The OSG 1651501108 is a spiral point tap designed for threading 10-24 UNC holes in a wide range of ferrous and non-ferrous metals. It features a plug chamfer, 3 flutes, and a TiCN coating over a powdered metal substrate rated at material grade PMT15. The spiral point geometry pushes chips forward ahead of the tap, making it well suited for through-hole tapping operations where chip evacuation is a priority. The H3 thread limit and 2B class of fit deliver consistent thread tolerance for standard fastener engagement. Licensed machinists, tooling technicians, and production machinists are the primary users.

This tap is built for use in manual tapping operations and CNC machining centers alike. Its material application range covers low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, hardened steel, die steel, cast iron, aluminum, and cast aluminum. The right-hand thread direction and standard 10-24 UNC sizing make it a common choice for general industrial thread repair, production tapping, and fixture work across job shops and manufacturing environments.

Key Features

• Spiral point geometry pushes chips forward, optimizing performance in through-hole applications
• TiCN coating improves wear resistance and extends tool life across abrasive materials
• Powdered metal construction (grade PMT15) provides enhanced toughness compared to standard HSS
• H3 thread limit holds 2B class of fit tolerances for reliable fastener compatibility
• No coolant-through design simplifies setup in standard machine tool spindles
• Right-hand thread direction, non-interrupted thread profile for clean engagement

Compatibility

Designed for tapping 10-24 UNC right-hand threads in alloy steel, aluminum, cast aluminum, cast iron, hardened steel, high-carbon steel, low-carbon steel, medium-carbon steel, stainless steel, and die steel. Fits standard straight-shank tap holders sized for a 0.194-inch shank diameter.

Installation Notes

Installation and use should follow standard machine shop safety practices. Ensure the workpiece is securely fixtured and the spindle is properly aligned before engaging the tap. Use appropriate cutting fluid for the workpiece material to reduce friction and extend tool life. Inspect the tap for wear or chipping before each use, as a damaged tap can seize in the hole or produce out-of-tolerance threads.
