Osg 1405003708 Thread Forming Tap 6-32 Unc Ticn Coated

Product Description

The OSG 1405003708 is a thread forming tap in the EXOTAP VP-NRT series, designed for cold-forming internal threads without cutting. It operates on a 6-32 UNC thread standard with a modified bottoming chamfer of 2 to 2.5 threads, making it suitable for blind hole threading applications where thread depth control is critical. The tap is manufactured from powdered metal high-speed steel and carries a TiCN coating, which improves surface hardness and wear resistance during high-cycle production runs. Overall length is 2 inches with a thread limit of H4. Installation is performed by machinists and maintenance technicians working with precision fastener assemblies.

This tap is intended for blind hole threading in a range of ferrous and non-ferrous materials. Rated material applications include alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. The EXOTAP VP-NRT series is engineered for cold-forming, meaning it displaces material rather than cutting chips, which reduces the risk of chip packing in blind holes. It is well suited to production environments where consistent thread quality and tap longevity are priorities.

Key Features

• Thread forming design eliminates chips, reducing risk of chip packing in blind holes
• Modified bottoming chamfer with 2 to 2.5 chamfered threads for close-to-bottom threading
• Powdered metal high-speed steel construction for improved wear resistance over standard HSS
• TiCN coating adds surface hardness and reduces friction during forming
• H4 thread limit for controlled tolerance in precision fastener applications
• Right-hand thread direction, 32 threads per inch, 6-32 UNC standard

Compatibility

Compatible material applications include alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel. Designed for blind hole threading operations on 6-32 UNC fastener patterns. Part of the OSG EXOTAP VP-NRT series 14050.

Installation Notes

This tap should be installed in a suitable tapping holder or CNC rigid tapping setup by a qualified machinist. Verify correct pilot hole diameter for thread forming before operation, as forming taps require a larger pilot hole than cutting taps of the same thread size. Ensure the workpiece is properly fixtured and that spindle speed and feed rate are set per OSG EXOTAP guidelines for the specific material being tapped. Coolant through is not available on this tap; use appropriate external cutting fluid for the workpiece material.
