Osg 1405006208 Thread Forming Tap 10-32 Unf Ticn Hss

Product Description

The OSG 1405006208 is a thread forming tap designed for cold-forming internal threads in ductile metals without cutting or producing chips. Built from powdered metal high-speed steel with a TiCN coating, this tap delivers high wear resistance and extended tool life in demanding production environments. It is configured with a modified bottoming chamfer of 2 to 2.5 threads, allowing thread forming close to the bottom of blind holes. The 10-32 UNF thread profile and H5 thread limit make it suitable for precision fastener applications where consistent thread class 2B fit is required. Licensed machinists and toolroom professionals are the primary users of this tap in CNC and manual tapping operations.

This tap is intended for blind hole threading in a range of ferrous and non-ferrous materials including alloy steel, carbon steel, die steel, hardened steel, stainless steel, and aluminum. The EXOTAP VP-NRT series is engineered for thread forming rather than thread cutting, making it well suited for applications where chip evacuation is problematic or where stronger thread form is desired. Right-hand thread direction is standard. No coolant-through capability is included, so external coolant or tapping fluid application is standard practice for this tool.

Key Features

• Thread forming design produces no chips, reducing blind hole clogging risk
• TiCN coating increases surface hardness and reduces friction for longer tool life
• Powdered metal high-speed steel substrate provides superior toughness over conventional HSS
• Modified bottoming chamfer (2 to 2.5P) enables threading close to blind hole bottom
• H5 thread limit ensures consistent class 2B fit on 10-32 UNF threads
• Right-hand thread direction with 0.492-inch thread length and 0.866-inch tapping depth

Compatibility

Designed for use on alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel workpieces. Suitable for blind hole threading applications requiring a 10-32 UNF class 2B thread form. Part of OSG EXOTAP VP-NRT series 14050.

Installation Notes

This tap should be installed in a tap holder or CNC machine spindle rated for the shank diameter of 0.194 inches. Power down or lock out any machine before loading or removing the tap from the holder. Apply appropriate tapping fluid or cutting oil to the workpiece when operating without coolant-through capability. Follow the machine manufacturer and tool manufacturer feed and speed recommendations for the specific workpiece material to avoid tap breakage or thread damage.
