Osg 1101500505 Spiral Point Tap 6-32 Unc Tin Hss

Product Description

The OSG 1101500505 is a spiral point plug tap designed for threading 6-32 UNC holes in a wide range of ferrous and non-ferrous materials. Manufactured from vanadium high speed steel and finished with a titanium nitride (TiN) coating, this tap provides increased surface hardness and lubricity for extended tool life under production conditions. The 3-flute spiral point geometry pushes chips forward ahead of the cutting zone, making it well suited for through-hole tapping applications. With an H5 thread limit and right-hand thread direction, it produces consistent, close-tolerance threads at the 6-32 UNC standard. Overall length is 2 inches with a thread length of 0.433 inches.

This tap is intended for use in machine tapping operations across general metalworking, maintenance, and production environments. The TiN coating and vanadium HSS construction make it appropriate for tapping 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 typically used by machinists, tool and die technicians, and maintenance trades requiring precise 6-32 UNC threaded holes. The plug chamfer style is the standard choice for through-hole threading where chip clearance is available ahead of the tap.

Key Features

• Spiral point geometry pushes chips forward, reducing clogging in through-hole applications
• TiN coating increases surface hardness and reduces friction for longer tool life
• Vanadium high speed steel construction handles a broad range of work materials
• H5 thread limit delivers close-tolerance 6-32 UNC threads
• Right-hand, plug chamfer style for standard through-hole tapping
• 3-flute design balances cutting load and chip evacuation

Compatibility

Designed as a machine tap for through-hole 6-32 UNC threading operations. Compatible work materials include aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, cast iron, high-nickel alloys, and titanium.

Installation Notes

This tap is intended for use by qualified machinists or maintenance technicians operating drill presses, CNC machining centers, or tapping machines. Before tapping, ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill size for 6-32 UNC. Use appropriate cutting fluid for the work material to reduce heat and extend tap life. Never force a tap against resistance - back off periodically to break and clear chips, especially in blind holes.
