Osg 2885200 Spiral Point Tap 6-32 Unc 2 Flute Hss

Product Description

The OSG 2885200 is a spiral point tap designed for threading 6-32 UNC holes in metalworking applications. Also known as a gun tap, this tool pushes chips ahead of the cut rather than backing them out, making it well suited for through-hole tapping operations. It features a plug chamfer, 2 flutes, High Speed Steel (HSS) construction, and a bright finish with no coating. The H3 thread limit provides consistent tolerance control for 2B class of fit threads. Overall length is 2 inches, with a thread length of 0.39 inches (11/16 inches nominal) and a shank diameter of 0.141 inches. Right-hand thread direction. Machinists, tool and die makers, and maintenance technicians install this tap in both manual and CNC tapping operations.

The OSG 2885200 is intended for through-hole tapping in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel. The spiral point geometry drives chips forward into the hole, reducing the risk of chip packing in production or high-volume repair environments. It is appropriate for use in drill presses, CNC machining centers, and hand tapping setups where a 6-32 UNC thread is required. The plug chamfer style is the standard choice when tapping through holes where the tap can pass fully through the workpiece material.

Key Features

• 6-32 UNC thread form with H3 thread limit for 2B class of fit tolerance
• Spiral point (gun tap) geometry pushes chips forward, suited for through-hole tapping
• High Speed Steel construction provides durability across a range of common workpiece materials
• Plug chamfer style for standard through-hole applications
• Bright finish with no coating, suitable for use with cutting fluids
• Right-hand thread direction, 2 flutes

Compatibility

Designed for tapping 6-32 UNC through holes in aluminum, cast aluminum, low-carbon steel, and medium-carbon steel workpieces using standard tap holders accepting a 0.141-inch shank diameter.

Installation Notes

This tap is installed by machinists and maintenance technicians using a standard tap wrench, tapping head, or CNC rigid tapping cycle. Ensure the workpiece is securely fixtured and that the tap is properly aligned to the drilled pilot hole before beginning the threading operation. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Do not force the tap if resistance increases unexpectedly, as breakage can occur and recovery from a broken tap in a small-diameter hole is difficult.
