Osg 2917408 Spiral Flute Tap 6-32 Unc Ticn Vanadium Hss

Product Description

The OSG 2917408 is a spiral flute tap designed for cutting 6-32 UNC right-hand internal threads in a range of ferrous materials. Built from vanadium high-speed steel and finished with a TiCN coating, it delivers extended tool life in demanding production and repair applications. The modified bottoming chamfer allows threading close to the bottom of blind holes. With a 45-degree helix angle and 3 right-hand flutes, the tool actively evacuates chips up and out of the hole, reducing the risk of tap breakage and recutting in tough materials.

This tap is suited for threading operations in alloy steel, carbon steel, cast iron, stainless steel, die steel, and hardened steel. It is commonly used by machinists and maintenance technicians in production shops, toolrooms, and field repair settings where 6-32 fastener threads are required in ferrous workpieces. The modified bottoming style makes it a practical choice when thread depth must reach near the bottom of a blind hole. It fits standard tap holders and machine spindles accepting the 0.141-inch shank diameter.

Key Features

• Vanadium high-speed steel construction for hardness and wear resistance in ferrous materials
• TiCN coating reduces friction and extends tool life compared to uncoated HSS taps
• 45-degree right-hand spiral flutes pull chips out of blind holes during cutting
• Modified bottoming chamfer allows threading close to the bottom of blind holes
• H5 thread limit provides controlled oversize tolerance for consistent fit
• Right-hand thread direction compatible with standard tapping equipment

Compatibility

Designed as a replacement or production tap for 6-32 UNC threading applications in alloy steel, carbon steel, cast iron, stainless steel, die steel, and hardened steel workpieces. Compatible with standard tap holders accepting a 0.141-inch shank diameter.

Installation Notes

Installation is performed by machinists or maintenance technicians using a tapping machine, drill press, or hand tap wrench. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for 6-32 UNC before tapping. Apply appropriate cutting fluid for the workpiece material to improve finish and tool life. Power down or de-energize any machine spindle before changing or inspecting the tap.
